Therav?da (Pali, literally "school of the elder monks") is a branch of Buddhism that uses the Buddha's teaching preserved in the P?li Canon as its doctrinal core. The Pali canon is the only complete Buddhist canon which survives in a classical Indic Language, Pali, which serves as the sacred language and lingua franca of Theravada Buddhism. Another feature of Theravada is that it tends to be very conservative about matters of doctrine and monastic discipline. As a distinct sect, Theravada Buddhism developed in Sri Lanka and spread to the rest of Southeast Asia.
Theravada also includes a rich diversity of traditions and practices that have developed over its long history of interactions with varying cultures and religious communities. It is the dominant form of religion in Cambodia, Laos, Myanmar, Sri Lanka, and Thailand, and is practiced by minority groups in India, Bangladesh, China, Nepal, and Vietnam. In addition, the diaspora of all of these groups as well as converts around the world practice Therav?da Buddhism. Contemporary expressions include Buddhist modernism, the Vipassana movement and the Thai Forest Tradition.
Therav?da Buddhism is followed by countries and people around the globe, and is:
Today, Therav?da Buddhists, otherwise known as Theravadins, number over 150 million worldwide, and during the past few decades Therav?da Buddhism has begun to take root in the West[a] and in the Buddhist revival in India.[web 2]
The name Therav?da comes[b] from the ancestral Sth?vir?ya, one of the early Buddhist schools, from which the Theravadins claim descent. After unsuccessfully trying to modify the Vinaya, a small group of "elderly members", i.e. sthaviras, broke away from the majority Mah?s??ghika during the Second Buddhist council, giving rise to the Sthavira sect. According to its own accounts, the Therav?da school is fundamentally derived from the Vibhajjav?da "doctrine of analysis" grouping, which was a division of the Sth?vir?ya.
Buddhists from the Indian mainland appear originally to have regarded the Buddhists of La?k? as simply the 'La?k? school', thus Vasubandhu writing in the fourth century cites the notion of the bhav??ga-vijñ?na of the T?mrapar??ya-nik?ya as a forerunner of the ?laya-vijñ?na. But beginning with Yijing's account of his travels in India (671-695 ce ) and Vin?tadeva's eighth-century summary of the divisions of the Buddhist schools (Samaya-bhedoparacana- cakra-nik?ya-bhedopadar?ana-cakra), we find north Indian sources describing the Buddhist Sa?gha as comprising four nik?yas: (1) the Mah?s??ghikas, (2) the Sth?viras, (3) the Sarv?stiv?dins, and (4) the Sa?mat?yas. Significantly, the Sth?viras in turn comprise three sub-nik?yas: the Jetavan?yas, the Abhayagiriv?sins, and the Mah?vih?rav?sins. The Buddhists of La?k? are thus no longer regarded as the 'La?k? school', they are the Sth?viras, despite the fact that both the Sarv?stiv?dins and the Sa?mat?yas were also understood as tracing their lineage to the Sth?vira side of the original split with the Mah?s??ghikas. The reason for referring to the three Buddhist nik?yas of La?k? as the Sth?viras is probably not so much a recognition of an exclusive claim to be the authentic therav?da, as a reflection of the simple fact that the La?k? schools alone of the various Sth?vira schools continued to refer to themselves as theriya or therav?da in certain contexts.
According to Damien Keown, there is no historical evidence that the Therav?da school arose until around two centuries after the Great Schism which occurred at the Third Council. Theravadin accounts of its own origins mention that it received the teachings that were agreed upon during the putative Third Buddhist council under the patronage of the Indian Emperor Ashoka around 250 BCE. These teachings were known as the Vibhajjavada. Emperor Ashoka is supposed to have assisted in purifying the sangha by expelling monks who failed to agree to the terms of Third Council. The elder monk Moggaliputta-Tissa was at the head of the Third council and compiled the Kathavatthu ("Points of Controversy"), a refutation of various opposing views which is an important work in the Theravada Abhidhamma.
The Therav?da is said to be descended from the T?mrapar??ya sect, which means "the Sri Lankan lineage". Missionaries sent abroad from India are said to have included Ashoka's son Mahinda (who studied under Moggaliputta-Tissa) and his daughter Sanghamitta, and they were the mythical founders of Buddhism in Sri Lanka, a story which scholars suggest helps to legitimize Therav?da's claims of being the oldest and most authentic school. According to the Mahavamsa chronicle their arrival in Sri Lanka is said to have been during the reign of Devanampiya Tissa of Anuradhapura (307 BCE to 267 BCE) who converted to Buddhism and helped build the first Buddhist stupas. According to S.D. Bandaranayake:
"The rapid spread of Buddhism and the emergence of an extensive organization of the sangha are closely linked with the secular authority of the central state...There are no known artistic or architectural remains from this epoch except for the cave dwellings of the monks, reflecting the growth and spread of the new religion. The most distinctive features of this phase and virtually the only contemporary historical material, are the numerous Brahmi inscriptions associated with these caves. They record gifts to the sangha, significantly by householders and chiefs rather than by kings. The Buddhist religion itself does not seem to have established undisputed authority until the reigns of Dutthagamani and Vattagamani (ca mid-2nd century BCE to mid-1st century BCE)..."
The first records of Buddha images come from the reign of king Vasabha (65-109 BCE), and after the 3rd century AD the historical record shows a growth of the worship of Buddha images as well as Bodhisattvas.
In the 7th century, the Chinese pilgrim monks Xuanzang and Yijing refer to the Buddhist schools in Sri Lanka as Shàngzuòbù (Chinese: ???), corresponding to the Sanskrit Sthavira nik?ya and Pali Thera Nik?ya.Yijing writes, "In Sri Lanka the Sthavira school alone flourishes; the Mahasanghikas are expelled".
The school has been using the name Therav?da for itself in a written form since at least the 4th century, about one thousand years after the Buddha's death, when the term appears in the D?pava?sa.[need quotation to verify]
According to Buddhist scholar A. K. Warder, the Therav?da
... spread rapidly south from Avanti into Maharashtra and Andhra and down to the Chola country (Kanchi), as well as Sri Lanka. For some time they maintained themselves in Avanti as well as in their new territories, but gradually they tended to regroup themselves in the south, the Great Vihara (Mahavihara) in Anuradhapura, the ancient capital of Sri Lanka, becoming the main centre of their tradition, Kanchi a secondary center and the northern regions apparently relinquished to other schools.
Between the reigns of Sena I (833-853) and Mahinda IV (956-972), the city of Anuradhapura saw a "colossal building effort" by various kings during a long period of peace and prosperity, the great part of the present architectural remains in this city date from this period.
The Sri Lankan Buddhist Sangha initially preserved the Buddhist scriptures (the Tipitaka) orally as it had been traditionally done, however during the first century BCE, famine and wars led to the writing down of these scriptures. The Sri Lankan chronicle The Mahavamsa records:
"Formerly clever monks preserved the text of the Canon and its commentaries orally, but then, when they saw the disastrous state of living beings, they came together and had it written down in books, that the doctrine might long survive."
According to Richard Gombrich this is "the earliest record we have of Buddhist scriptures being committed to writing anywhere." The Theravada Pali texts which have survived (with only a few exceptions) are derived from the Mahavihara (monastic complex) of Anuradhapura, the ancient Sri Lankan capital.
Later developments included the formation and recording of the Theravada commentary literature (Atthakatha). The Theravada tradition records that even during the early days of Mahinda, there was already a tradition of Indian commentaries on the scriptures. Prior to the writing of the classic Theravada Pali commentaries, there were also various commentaries on the Tipitaka written in the Sinhalese language, such as the Maha-atthakatha ("Great commentary"), the main commentary tradition of the Mahavihara monks.
Of great importance to the commentary tradition is the work of the great Theravada scholastic Buddhaghosa (4-5th century CE), who is responsible for most of the Theravada commentary literature that has survived (any older commentaries have been lost). Buddhaghosa wrote in Pali, and after him, most Sri Lankan Buddhist scholastics did as well. This allowed the Sri Lankan tradition to become more international through a lingua franca so as to converse with monks in India and later Southeast Asia.
Theravada monks also produced other Pali literature such as historical chronicles (e.g. Mahavamsa), hagiographies, practice manuals, summaries, textbooks, poetry and Abhidhamma works such as the Abhidhammattha-sangaha and the Abhidhammavatara. Buddhaghosa's work on Abhidhamma and Buddhist practice outlined in works such as the Visuddhimagga and the Atthasalini are the most influential texts apart from the Pali Canon texts themselves in the Theravada tradition. Other Theravada Pali commentators and writers include Dhammapala and Buddhadatta. Dhammapala wrote commentaries on the Pali Canon texts which Buddhaghosa had omitted and also wrote a commentary called the Paramathamanjusa on Buddhaghosa's great manual, the Visuddhimagga.
Over much of the early history of Buddhism in Sri Lanka, three subdivisions of Therav?da existed in Sri Lanka, consisting of the monks of the Mah?vih?ra, Abhayagiri vih?ra and Jetavana. The Mah?vih?ra was the first tradition to be established, while Abhayagiri Vih?ra and Jetavana Vih?ra were established by monks who had broken away from the Mah?vih?ra tradition. According to A.K. Warder, the Indian Mah???saka sect also established itself in Sri Lanka alongside the Therav?da, into which they were later absorbed. Northern regions of Sri Lanka also seem to have been ceded to sects from India at certain times.
The Mahavihara ("Great Monastery") school became dominant in Sri Lanka at the beginning of the 2nd millennium CE and gradually spread through mainland Southeast Asia. It was established in Myanmar in the late 11th century, in Thailand in the 13th and early 14th centuries, and in Cambodia and Laos by the end of the 14th century. Although Mahavihara never completely replaced other schools in Southeast Asia, it received special favor at most royal courts. This is due to the support it received from local elites, who exerted a very strong religious and social influence. 
Theravada, a group of monks who disagreed with the Mahavihara way, decided to rebel and form their own alliance group. Mahavihara was essential to Theravada, because it was in fact the center of Theravada Buddhism. It was responsible for the development of Sri Lankan people, based off their religious beliefs and acceptable lifestyle. In the religious sense of Theravada, there are no further subdivisions, if Mahavihara does not cease to exist. 
Over the centuries, the Abhayagiri Therav?dins maintained close relations with Indian Buddhists and adopted many new teachings from India. including many elements from Mah?y?na teachings, while the Jetavana Therav?dins adopted Mah?y?na to a lesser extent.
Xuanzang wrote of two major divisions of Therav?da in Sri Lanka, referring to the Abhayagiri tradition as the "Mah?y?na Sthaviras", and the Mah?vih?ra tradition as the "H?nay?na Sthaviras". Xuanzang further writes:
The Mah?vih?rav?sins reject the Mah?y?na and practise the H?nay?na, while the Abhayagirivih?rav?sins study both H?nay?na and Mah?y?na teachings and propagate the Tripi?aka.
Akira Hirakawa notes that the surviving P?li commentaries (A??hakath?) of the Mah?vih?ra school, when examined closely, also include a number of positions that agree with Mah?y?na teachings. Kalupahana notes the same for the Visuddhimagga, the most important Therav?da commentary.
It is known that in the 8th century, both Mah?y?na and the esoteric Vajray?na form of Buddhism were being practised in Sri Lanka, and two Indian monks responsible for propagating Esoteric Buddhism in China, Vajrabodhi and Amoghavajra, visited the island during this time. Abhayagiri Vih?ra appears to have been a center for Theravadin Mah?y?na and Vajray?na teachings.
Some scholars have held that the rulers of Sri Lanka ensured that Therav?da remained traditional, and that this characteristic contrasts with Indian Buddhism. However, before the 12th century, more rulers of Sri Lanka gave support and patronage to the Abhayagiri Therav?dins, and travelers such as Faxian saw the Abhayagiri Therav?dins as the main Buddhist tradition in Sri Lanka.
The trend of the Abhayagiri Vihara being the dominant sect changed in the 12th century, when the Mah?vih?ra sect gained the political support of Parakramabahu I (1153-1186), who completely abolished the Abhayagiri and Jetavanin traditions. The Therav?da monks of these two traditions were then defrocked and given the choice of either returning to the laity permanently, or attempting reordination under the Mah?vih?ra tradition as "novices" (s?ma?era).Richard Gombrich writes:
Though the chronicle says that he reunited the Sangha, this expression glosses over the fact that what he did was to abolish the Abhayagiri and Jetavana Nik?yas. He laicized many monks from the Mah? Vih?ra Nik?ya, all the monks in the other two - and then allowed the better ones among the latter to become novices in the now 'unified' Sangha, into which they would have in due course to be reordained.
Regarding the differences between these three Therav?da traditions, the C??ava?sa laments, "Despite the vast efforts made in every way by former kings down to the present day, the Bhikkhus turned away in their demeanor from one another and took delight in all kinds of strife."
Parakkamab?hu I rebuilt the ancient cities of Anuradhapura and Polonnaruwa, restoring Buddhist stupas and Viharas (monasteries). He appointed a Sangharaja, or "King of the Sangha", a monk who would preside over the Sangha and its ordinations in Sri Lanka, assisted by two deputies. The reign of Parakkamab?hu also saw a flowering of Theravada scholasticism with the work of prominent Sri Lankan scholars such as Anuruddha, S?riputta Thera, Mah?kassapa Thera of Dimbulagala Vihara and Moggallana Thera. They worked on compiling of subcommentaries on the Tipitaka, texts on grammar, summaries and textbooks on Abhidhamma and Vinaya such as the influential Abhidhammattha-sangaha of Anuruddha.
A few years after the arrival of Mahinda, the bhikkhu Sa?ghamitt?, who is also believed to have been the daughter of Ashoka, came to Sri Lanka. She ordained the first nuns in Sri Lanka. In 429, by request of China's emperor, nuns from Anuradhapura were sent to China to establish the order there, which subsequently spread across East Asia. The pr?timok?a of the nun's order in East Asian Buddhism is the Dharmaguptaka, which is different than the pr?timok?a of the current Theravada school; the specific ordination of the early Sangha in Sri Lanka not known, although the Dharmaguptaka sect originated with the Sth?vir?ya as well.
The nun's order subsequently died out in Sri Lanka in the 11th century and in Burma in the 13th century. It had already died out around the 10th century in other Theravadin areas. Novice ordination has also disappeared in those countries. Therefore, women who wish to live as renunciates in those countries must do so by taking eight or ten precepts. Neither laywomen nor formally ordained, these women do not receive the recognition, education, financial support or status enjoyed by Buddhist men in their countries. These "precept-holders" live in Myanmar, Cambodia, Laos, Nepal, and Thailand. In particular, the governing council of Burmese Buddhism has ruled that there can be no valid ordination of women in modern times, though some Burmese monks disagree. Japan is a special case as, although it has neither the bhikkhuni nor novice ordinations, the precept-holding nuns who live there do enjoy a higher status and better education than their precept-holder sisters elsewhere, and can even become Zen priests. In Tibet there is currently no bhikkhuni ordination, but the Dalai Lama has authorized followers of the Tibetan tradition to be ordained as nuns in traditions that have such ordination.
In 1996, 11 selected Sri Lankan women were ordained fully as Theravada bhikkhunis by a team of Therav?da monks in concert with a team of Korean nuns in India. There is disagreement among Therav?da vinaya authorities as to whether such ordinations are valid. The Dambulla chapter of the Siam Nikaya in Sri Lanka also carried out a nun's ordination at this time, specifically stating their ordination process was a valid Theravadin process where the other ordination session was not. This chapter has carried out ordination ceremonies for hundreds of nuns since then. This has been criticized by leading figures in the Siam Nikaya and Amarapura Nikaya, and the governing council of Buddhism in Myanmar has declared that there can be no valid ordination of nuns in modern times, though some Burmese monks disagree with this.
In 1997 Dhamma Cetiya Vihara in Boston was founded by Ven. Gotami of Thailand, then a 10 precept nun; when she received full ordination in 2000, her dwelling became America's first Theravada Buddhist bhikkhuni vihara.
A 55-year-old Thai Buddhist 8-precept white-robed maechee nun, Varanggana Vanavichayen, became the first woman to receive the going-forth ceremony of a Theravada novice (and the gold robe) in Thailand, in 2002. On February 28, 2003, Dhammananda Bhikkhuni, formerly known as Chatsumarn Kabilsingh, became the first Thai woman to receive bhikkhuni ordination as a Theravada nun. Dhammananda Bhikkhuni was ordained in Sri Lanka. The Thai Senate has reviewed and revoked the secular law passed in 1928 banning women's full ordination in Buddhism as unconstitutional for being counter to laws protecting freedom of religion. However Thailand's two main Theravada Buddhist orders, the Mahanikaya and Dhammayutika Nikaya, have yet to officially accept fully ordained women into their ranks.
In 2009 in Australia four women received bhikkhuni ordination as Theravada nuns, the first time such ordination had occurred in Australia. It was performed in Perth, Australia, on 22 October 2009 at Bodhinyana Monastery. Abbess Vayama together with Venerables Nirodha, Seri, and Hasapanna were ordained as Bhikkhunis by a dual Sangha act of Bhikkhus and Bhikkhunis in full accordance with the Pali Vinaya.
In 2010, in Northern California, four novice nuns were given the full bhikkhuni ordination in the Thai Theravada tradition, which included the double ordination ceremony. Henepola Gunaratana and other monks and nuns were in attendance. It was the first such ordination ever in the Western hemisphere.
The first bhikkhuni ordination in Germany, the ordination of German woman Samaneri Dhira, occurred on June 21, 2015 at Anenja Vihara.
In Indonesia, the first Theravada ordination of bhikkhunis in Indonesia after more than a thousand years occurred in 2015 at Wisma Kusalayani in Lembang, Bandung in West Java. Those ordained included Vajiradevi Sadhika Bhikkhuni from Indonesia, Medha Bhikkhuni from Sri Lanka, Anula Bhikkhuni from Japan, Santasukha Santamana Bhikkhuni from Vietnam, Sukhi Bhikkhuni and Sumangala Bhikkhuni from Malaysia, and Jenti Bhikkhuni from Australia.
According to the Mahavamsa, a Sri Lankan chronicle, after the conclusion of the Third Buddhist council, a mission was sent to Suvarnabhumi, led by two monks, Sona and Uttara. Scholarly opinions differ as to where exactly this land of Suvarnabhumi was located, but it is generally believed to have been located somewhere in the area of Lower Burma, Thailand, the Malay Peninsula, or Sumatra.
Before the 12th century, the areas of Thailand, Myanmar, Laos, and Cambodia were dominated by Buddhist sects from India, and included the teachings of Mah?y?na Buddhism. In the 7th century, Yijing noted in his travels that in these areas, all major sects of Indian Buddhism flourished.
Though there are some early accounts that have been interpreted as Therav?da in Myanmar, the surviving records show that most Burmese Buddhism incorporated Mah?y?na, and used Sanskrit rather than Pali. After the decline of Buddhism in India, missions of monks from Sri Lanka gradually converted Burmese Buddhism to Therav?da, and in the next two centuries also brought Therav?da Buddhism to the areas of Thailand, Laos, and Cambodia, where it supplanted previous forms of Buddhism.
The Mon and Pyu were among the earliest people to inhabit Myanmar. The oldest surviving Buddhist texts in the Pali language come from Pyu city-state of Sri Ksetra, the text which is dated from the mid 5th to mid 6th century is written on twenty-leaf manuscript of solid gold. According to Peter Skilling: "From the point of view of both language and contents, I conclude that the Pali inscriptions of Burma and Siam give firm evidence for a Theravadin presence in the Irrawaddy and Chao Phraya basins, from about the 5th century CE onwards. From the extent and richness of the evidence it seems that the Theravada was the predominant school, and that it enjoyed the patronage of ruling and economic elites. But I do not mean to suggest that religious society was monolithic: other schools may well have been present, or have come and gone, and there is ample evidence for the practice of Mahayana and Brahmanism in the region."
The Burmese slowly became Therav?dan as they came into contact and conquered the Pyu and Mon civilizations. This began in the 11th century during the reign of the Bamar king Anawrahta (1044-1077) of the Pagan Kingdom who acquired the Pali scriptures in a war against the Mon as well as from Sri Lanka and build stupas and monasteries at his capital of Bagan. Various invasions of Burma by neighboring states and the Mongol invasions of Burma (13th century) damaged the Burmese sangha and Theravada had to be reintroduced several times into the country from Sri Lanka and Thailand.
The Khmer Empire (802-1431) centered in Cambodia was initially dominated by Hinduism, Hindu ceremonies and rituals were performed by Brahmins, usually only held among ruling elites of the king's family, nobles, and the ruling class. Tantric Mahayana Buddhism was also a prominent faith, promoted by Buddhist emperors such as Jayavarman VII (1181-1215) who rejected the Hindu gods and presented himself as a Bodhisattva King.
King Jayavarman VII (reigned c.1181-1218) had sent his son Tamalinda to Sri Lanka to be ordained as a Buddhist monk and study Theravada Buddhism according to the Pali scriptural traditions in the Mahavihara monastery. Tamalinda then returned to Cambodia and promoted Buddhist traditions according to the Theravada training he had received, galvanizing and energizing the long-standing Theravada presence that had existed throughout the Angkor empire for centuries. During the 13th and 14th centuries, Theravada monks from Sri Lanka continued introducing orthodox Theravada Buddhism which eventually became the dominant faith among all classes. The monasteries replaced the local priestly classes, becoming centers of religion, education, culture and social service for Cambodian villages. This led to high levels of literacy among Cambodians.
In Thailand, Theravada existed alongside Mahayana and other religious sects before the rise of Sukhothai Kingdom. During the reign of King Ram Khamhaeng (c. 1237/1247 - 1298) Theravada was made the main state religion and promoted by the king.
During the pre-modern era, Southeast Asian Buddhism included numerous elements which could be called tantric and esoteric (such as the use of mantras and yantras in elaborate rituals). The French scholar François Bizot has called this "Tantric Theravada", and his textual studies show that it was a major tradition in Cambodia and Thailand. Some of these practices are still prevalent in Cambodia and Laos today.
Despite its success in Southeast Asia, Therav?da Buddhism in China has generally been limited to areas bordering Therav?da countries.
In the 19th century began a process of mutual influence of both Asian Theravadins and a Western audience interested in ancient wisdom. Especially Helena Blavatsky and Henry Steel Olcott, founders of the Theosophical Society had a profound role in this process. In Therav?da countries a lay vipassana practice developed. From the 1970s on, Western interest gave way to the growth of the Vipassana movement in the West.
Buddhist revivalism has also reacted against changes in Buddhism caused by colonialist regimes. Western colonialists and Christian missionaries deliberately imposed a particular type of Christian monasticism on Buddhist clergy in Sri Lanka and colonies in Southeast Asia, restricting monks' activities to individual purification and temple ministries. Prior to British colonial control, monks in both Sri Lanka and Burma had been responsible for the education of the children of lay people, and had produced large bodies of literature. After the British takeover, Buddhist temples were strictly administered and were only permitted to use their funds on strictly religious activities. Christian ministers were given control of the education system and their pay became state funding for missions.
Foreign, especially British, rule had an enervating effect on the sangha. According to Walpola Rahula, Christian missionaries displaced and appropriated the educational, social, and welfare activities of the monks, and inculcated a permanent shift in views regarding the proper position of monks in society through their institutional influence upon the elite. Many monks in post-colonial times have dedicated themselves to undoing these changes. Movements intending to restore Buddhism's place in society have developed in both Sri Lanka and Myanmar.
One consequence of the reaction against Western colonialism has been a modernization of Therav?da Buddhism: Western elements have been incorporated, and meditation practice has opened to a lay audience. Modernized forms of Therav?dan practice have spread to the West.
In Sri Lanka Theravadins were looking at Western culture to find means to revitalize their own tradition. Christian missionaries were threatening the indigenous culture. As a reaction to this, Theravadins started to propagate Therav?da Buddhism. They were aided by the Theosophical Society, who were dedicated to the search for wisdom within ancient sources, including Buddhism and the P?li Canon. Anagarika Dharmapala was one of the Therav?da leaders with whom the Theosophists sided. Dharmapala tried to reinstate vipassan?, using the Visuddhimagga and the Pali Canon as a foundation. Dharmapala reached out to the middle classes, offering them religious practice and a religious identity, which were used to withstand the British imperialists. As a result of Dharmapapla's efforts lay practitioners started to practise meditation, which had been reserved specifically for the monks.
The translation and publication of the P?li Canon by the Pali Text Society made the Pali Canon better available to a lay audience, not only in the West, but also in the East. Western lay interest in Therav?da Buddhism was promoted by the Theosophical Society, and endured until the beginning of the 20th century. During the 1970s interest rose again, leading to a surge of Westerners searching for enlightenment, and the republishing of the P?li Canon, first in print, and later on the internet.
With the coming to power in 1851 of King Mongkut, who had been a monk himself for twenty-seven years, the sangha, like the kingdom, became steadily more centralized and hierarchical, and its links to the state more institutionalized. Mongkut was a distinguished scholar of Pali Buddhist scripture. Moreover, at that time the immigration of numbers of monks from Burma was introducing the more rigorous discipline characteristic of the Mon sangha. Influenced by the Mon and guided by his own understanding of the Tipitaka, Mongkut began a reform movement that later became the basis for the Dhammayuttika Nikaya.
In the early 1900s, Thailand's Ajahn Sao Kantas?lo and his student, Mun Bhuridatta, led the Thai Forest Tradition revival movement. In the 20th century notable practitioners included Ajahn Thate, Ajahn Maha Bua and Ajahn Chah. It was later spread globally by Ajahn Mun's students including Ajahn Thate, Ajahn Maha Bua and Ajahn Chah and several Western disciples, among whom the most senior is Luang Por Ajahn Sumedho.
Burmese Therav?da Buddhism has had a profound influence on modern vipassan? practice, both for lay practitioners in Asia as in the West.
The "New Burmese method" was developed by U N?rada and popularized by his student Mahasi Sayadaw and Nyanaponika Thera. Another prominent teacher is Bhikkhu Bodhi, a student of Nyanaponika. The New Burmese Method strongly emphasizes vipassan? over samatha. It is regarded as a simplification of traditional Buddhist meditation techniques, suitable not only for monks but also for lay practitioners. The method has been popularized in the West by teachers as Joseph Goldstein, Jack Kornfield, Tara Brach, Gil Fronsdal and Sharon Salzberg.
The Ledi lineage begins with Ledi Sayadaw.S. N. Goenka is a well-known teacher in the Ledi-lineage. According to S. N. Goenka, vipassana techniques are essentially nonsectarian in character, and have universal application. Meditation centers teaching the vipassan? popularized by S. N. Goenka exist now in India, Asia, North and South America, Europe, Australia, Middle East and Africa.
The Sth?vir?ya, from which Therav?da is derived, differed from other early Buddhist schools on a variety of teachings that are maintained by the Therav?da school. The differences resulted from the systemization of the Buddhist teachings, which was preserved in the abhidharmas of the various schools.
The abhidhamma is "a restatement of the doctrine of the Buddha in strictly formalised language [...] assumed to constitute a consistent system of philosophy". Its aim is not the empirical verification of the Buddhist teachings, but "to set forth the correct interpretation of the Buddha's statements in the Sutra to restate his 'system' with perfect accuracy".
According to the Therav?da, "progress in understanding comes all at once, 'insight' (abhisamaya) does not come 'gradually' (successively - anapurva)", a belief known as subitism. This is reflected in the Therav?da account on the four stages of enlightenment, in which the attainment of the four paths appears suddenly and the defilements are rooted out at once. The same stance is taken in the contemporary vipassana movement, especially the "New Burmese Method".
The commentaries gave a new definition of "a 'principle' or 'element' (dharma)":
[D]harmas are what have (or 'hold', 'maintain', dhr is the nearest equivalent in the language to the English 'have') their own own-being (svabhava). It is added that they naturally (yathasvabhavatas) have this through conditions (pratyaya). The idea is that they are distinct, definable, principles in the constitution of the universe."
Therav?da promotes the concept of vibhajjav?da "teaching of analysis". This doctrine says that insight must come from the aspirant's experience, application of knowledge, and critical reasoning. However, the scriptures of the Theravadin tradition also emphasize heeding the advice of the wise, considering such advice and evaluation of one's own experiences to be the two tests by which practices should be judged.
Therav?da orthodoxy takes the seven stages of purification as its basic outline of the path to be followed.
The Therav?da Path starts with learning, to be followed by practise, culminating in the realization of Nirvana.[c]
Throughout the Pali Canon, two characteristics of all sa?kh?ra (conditioned phenomena) and one characteristic of all dhammas are mentioned. The Therav?da tradition has grouped them together. Insight into these three characteristics is the entry to the Buddhist path:
The Four Noble Truths are described as follows:
In Therav?da, the cause of human existence and suffering (dukkha) is identified as ta?h? (craving), which carries with it the kilesas (defilements). Those defilements that bind humans to the cycle of rebirth are classified into a set of ten fetters, while those defilements - sometimes referred to in English as "toxic mental states" - that impede samadhi (concentration) are presented in a fivefold set called the five hindrances.[web 5] The level of defilement can be coarse, medium, and subtle. It is a phenomenon that frequently arises, remains temporarily and then vanishes. Theravadins believe defilements are not only harmful to oneself, but also harmful to others. They are the driving force behind all inhumanities a human being can commit.
There are three stages of defilements. During the stage of passivity the defilements lie dormant at the base of the mental continuum as latent tendencies (anusaya), but through the impact of sensory stimulus, they will manifest (pariyutthana) themselves at the surface of consciousness in the form of unwholesome thoughts, emotions, and volitions. If they gather additional strength, the defilements will reach the dangerous stage of transgression (vitikkama), which will then involve physical or vocal actions.
Theravadins believe these defilements are habits born out of avijj? (ignorance) that afflict the minds of all unenlightened beings, who cling to them and their influence in their ignorance of the truth. But in reality, those mental defilements are nothing more than taints that have afflicted the mind, creating suffering and stress. Unenlightened beings cling to the body, under the assumption that it represents a Self, whereas in reality the body is an impermanent phenomenon formed from the mah?bh?ta. Often characterized by earth, water, fire and air, in the early Buddhist texts these are defined to be abstractions representing the sensorial qualities solidity, fluidity, temperature, and mobility, respectively.[d]
The mental defilements' frequent instigation and manipulation of the mind is believed to have prevented the mind from seeing the true nature of reality. Unskillful behavior in turn can strengthen the defilements, but following the Noble Eightfold Path can weaken or eradicate them. Avijj? is destroyed by insight.
The concept of cause and effect, or causality, is a key concept in Therav?da, and indeed, in Buddhism as a whole. This concept is expressed in several ways, including the Four Noble Truths, and most importantly, paticcasamupp?da (dependent co-arising).
Abhidharma in the Pali Canon differentiates between a root cause (hetu) and facilitating cause (pacca). By the combined interaction of both these, an effect is brought about. On top of this view, a logic is built and elaborated whose most supple form can be seen in paticcasamupp?da.
This concept is then used to question the nature of suffering and to elucidate the way out of it, as expressed in the Four Noble Truths. It is also employed in several suttas to refute several philosophies, or any belief system that takes a fixed mindset, or absolute beliefs about the nature of reality.
By taking away a cause, the result will also disappear. From this follows the Buddhist path to end suffering and existence in samsara.
Therav?da orthodoxy takes the seven stages of purification as the basic outline of the path to be followed. This basic outline is based on the threefold discipline of s?la (ethics or discipline), sam?dhi (meditative concentration) and paññ? (understanding or wisdom). The emphasis is on understanding the three marks of existence, which removes ignorance. Understanding destroys the ten fetters and leads to nibbana.
Theravadins believe that every individual is personally responsible for their own self-awakening and liberation, as they are the ones that were responsible for their own kamma (actions and consequences). Great emphasis is placed upon applying the knowledge through direct experience and personal realization, than believing about the known information about the nature of reality as said by the Buddha.
In the Sutta Pitaka, the path to liberation is described by the Noble Eightfold Path:
The Blessed One said, "Now what, monks, is the Noble Eightfold Path? Right view, right resolve, right speech, right action, right livelihood, right effort, right mindfulness, right concentration.[web 7]
The Visuddhimagga, written in the fifth century by Buddhaghosa, has become the orthodox account of the Therav?da path to liberation. It gives a sequence of seven purifications, based on the sequence of s?la, sam?dhi and paññ?.
It is composed of three sections, which discuss s?la, sam?dhi and pañña.
The seven purifications are:
The "Purification by Knowledge and Vision" is the culmination of the practice, in four stages leading to liberation and Nirvana.
The emphasis in this system is on understanding the three marks of existence, dukkha, anatta and anicca. This emphasis is recognizable in the value that is given to vipassan? over samatha, especially in the contemporary Vipassana movement.
Meditation (Pali: Bhavana) means the positive reinforcement of one's mind. Meditation is the key tool implemented in attaining jh?na. Samatha means "to make skillful", and has other renderings, among which are "tranquilizing, calming", "visualizing", and "achieving". Vipassan? means "insight" or "abstract understanding". In this context, Samatha Meditation makes a person skillful in concentration of mind. Once the mind is sufficiently concentrated, vipassan? allows one to see through the veil of ignorance.
In order to be free from suffering and stress, Theravadins believe that the defilements need to be permanently uprooted. Initially the defilements are restrained through mindfulness to prevent them from taking over mental and bodily action. They are then uprooted through internal investigation, analysis, experience and understanding of their true nature by using jh?na. This process needs to be repeated for each and every defilement. The practice will then lead the meditator to realize Nirvana.
Samatha meditation in Therav?da is usually involved with the concepts of kamma??h?na, which literally stands for "place of work"; in this context, it is the "place" or object of concentration (P?li: ?rammana) where the mind is at work. In samatha meditation, the mind is set at work concentrated on one particular entity. There are forty (40) such classic objects (entities) used in samatha meditation, which are termed kamma??h?na. By acquiring a kamma??h?na and practising samatha meditation, one would be able to attain certain elevated states of awareness and skill of the mind called Jhana. Practising samatha has samadhi as its ultimate goal.
It should be noted that samatha is not a method that is unique to Buddhism. In the suttas it is said to be implemented in other contemporary religions in India at the time of Buddha. In fact, the first teachers of Siddhartha, before they attained the state of awakening (P?li: Bodhi), are said to have been quite skillful in samatha (although the term had not been coined yet). In the Pali Canon, the Buddha frequently instructs his disciples to practise samadhi in order to establish and develop jh?na. Jh?na is the instrument used by the Buddha himself to penetrate the true nature of phenomena (through investigation and direct experience) and to reach Enlightenment.[web 12] Right Concentration (samma-samadhi) is one of the elements in the Noble Eightfold Path. Samadhi can be developed from mindfulness developed with kamma??h?na such as concentration on breathing (anapanasati), from visual objects (kasina), and repetition of phrases. The traditional list contains 40 objects of meditation (kamma??h?na) to be used for Samatha Meditation. Every object has a specific goal; for example, meditation on the parts of the body (kayanupassana or kayagathasathi) will result in a lessening of attachment to our own bodies and those of others, resulting in a reduction of sensual desires. Mett? generates the feelings of goodwill and sukha (happiness) toward ourselves and other beings; mett? practice serves as an antidote to ill-will, wrath and fear.
Practice leads to mundane and supramundane wisdom, leading to Nirvana:
The term "supramundane" [lokuttara] applies exclusively to that which transcends the world, that is the nine supramundane states: Nibbana, the four noble paths (magga) leading to Nibbana, and their corresponding fruits (phala) which experience the bliss of Nibbana.[web 11]
Each path is a momentary peak experience directly apprehending Nibbana and permanently cutting off certain defilements.[web 11]
Each path is followed by its supramundane fruit:
whereas the path performs the active function of cutting off defilements, fruition simply enjoys the bliss and peace that result when the path has completed its task. Also, where the path is limited to a single moment of consciousness, the fruition that follows immediately on the path endures for two or three moments. And while each of the four paths occurs only once and can never be repeated, fruition remains accessible to the noble disciple.[web 11]
Nirvana (Sanskrit: ???????, Nirv??a; Pali: ???????, Nibb?na; Thai: ??????, Nípphaan) is the ultimate goal of Theravadins. It is a state where the fire of the passions has been 'blown out', and the person is liberated from the repeated cycle of birth, illness, aging and death. In the Sa?yojanapuggala Sutta of the A?gutarra Nikaya, the Buddha describes four kinds of persons and tells us that the last person - the Arahant - has attained Nibbana by removing all 10 fetters that bind beings to samsara:
"In the Arahant. In this person, monks, all of the fetters ['sa?yojan?ni'] are gotten rid of that pertain to this world, give rise to rebirth, and give rise to becoming."
According to the early scriptures, the Nirvana attained by Arahants is identical to that attained by the Buddha himself, as there is only one type of Nirvana.[web 16] Theravadins believe the Buddha was superior to Arahants because the Buddha discovered the path all by himself and taught it to others (i.e., metaphorically turning the wheel of Dhamma). Arahants, on the other hand, attained Nirvana partly because of the Buddha's teachings. Theravadins revere the Buddha as a supremely gifted person but also recognize the existence of other such Buddhas in the distant past and future. Maitreya (Pali: Metteyya), for example, is mentioned very briefly in the Pali Canon as a Buddha who will come in the distant future.
The Therav?da school upholds the Pali Canon or Tipitaka as the most authoritative collection of texts on the teachings of Gautama Buddha. The Sutta and Vinaya portion of the Tipitaka shows considerable overlap in content to the Agamas, the parallel collections used by non-Therav?da schools in India which are preserved in Chinese and partially in Sanskrit, Prakrit, and Tibetan, and the various non-Therav?da Vinayas. On this basis, both these sets of texts are generally believed to be the oldest and most authoritative texts on Buddhism by scholars. It is also believed that much of the Pali Canon, which is still used by Therav?da communities, was transmitted to Sri Lanka during the reign of Ashoka. After being orally transmitted (as was the custom in those days for religious texts) for some centuries, were finally committed to writing in the last century BCE, at what the Therav?da usually reckons as the fourth council, in Sri Lanka. Therav?da is one of the first Buddhist schools to commit the whole complete set of its Buddhist canon into writing.
Much of the material in the Canon is not specifically "Therav?dan", but is instead the collection of teachings that this school preserved from the early, non-sectarian body of teachings. According to Peter Harvey:
The Therav?dans, then, may have added texts to the Canon for some time, but they do not appear to have tampered with what they already had from an earlier period.
The Pali Tipitaka consists of three parts: the Vinaya Pitaka, Sutta Pitaka and Abhidhamma Pitaka. Of these, the Abhidhamma Pitaka is believed to be a later addition to the first two pitakas, which, in the opinion of many scholars, were the only two pitakas at the time of the First Buddhist Council. The Pali Abhidhamma was not recognized outside the Therav?da school.
The Tipitaka is composed of 45 volumes in the Thai edition, 40 in the Burmese and 58 in the Sinhalese, and a full set of the Tipitaka is usually kept in its own (medium-sized) cupboard.
In the 4th or 5th century Buddhaghosa Thera wrote the first Pali commentaries to much of the Tipitaka (which were based on much older manuscripts, mostly in old Sinhalese). After him many other monks wrote various commentaries, which have become part of the Therav?da heritage. These texts do not have the same authority as the Tipitaka does, though Buddhaghosas Visuddhimagga is a cornerstone of the commentarial tradition.
The commentaries, together with the Abhidhamma, define the specific Therav?da heritage. Related versions of the Sutta Pitaka and Vinaya Pitaka were common to all the early Buddhist schools, and therefore do not define only Therav?da, but also the other early Buddhist schools, and perhaps the teaching of Gautama Buddha himself.
Therav?da Buddhists consider much of what is found in the Chinese and Tibetan Mah?y?na scriptural collections to be apocryphal, meaning that they are not authentic words of the Buddha.
Traditionally, Therav?da Buddhism has observed a distinction between the practices suitable for a lay person and the practices undertaken by ordained monks (in ancient times, there was a separate body of practices for nuns). While the possibility of significant attainment by laymen is not entirely disregarded by the Therav?da, it generally occupies a position of less prominence than in the Mah?y?na and Vajray?na traditions, with monastic life being hailed as a superior method of achieving Nirvana. The view that Therav?da, unlike other Buddhist schools, is primarily a monastic tradition has, however, been disputed.
Some Western scholars have erroneously tried to claim that Mah?y?na is primarily a religion for laymen and Therav?da is a primarily monastic religion. Both Mah?y?na and Therav?da have as their foundation strong monastic communities, which are almost identical in their regulations. Schools of Mah?y?na Buddhism without monastic communities of fully ordained monks and nuns are relatively recent and atypical developments, usually based on cultural and historical considerations rather than differences in fundamental doctrine. Both Mah?y?na and Therav?da also provided a clear and important place for lay followers.-- Ron Epstein, "Clearing Up Some Misconceptions about Buddhism"
This distinction between ordained monks and laypeople -- as well as the distinction between those practices advocated by the Pali Canon, and the folk religious elements embraced by many monks -- have motivated some scholars to consider Therav?da Buddhism to be composed of multiple separate traditions, overlapping though still distinct. Most prominently, the anthropologist Melford Spiro in his work Buddhism and Society separated Burmese Therav?da into three groups: Apotropaic Buddhism (concerned with providing protection from evil spirits), Kammatic Buddhism (concerned with making merit for a future birth), and Nibbanic Buddhism (concerned with attaining the liberation of Nirvana, as described in the Tipitaka). He stresses that all three are firmly rooted in the Pali Canon. These categories are not accepted by all scholars, and are usually considered non-exclusive by those who employ them.
The role of lay people has traditionally been primarily occupied with activities that are commonly termed merit making (falling under Spiro's category of kammatic Buddhism). Merit making activities include offering food and other basic necessities to monks, making donations to temples and monasteries, burning incense or lighting candles before images of the Buddha, and chanting protective or merit-making verses from the Pali Canon. Some lay practitioners have always chosen to take a more active role in religious affairs, while still maintaining their lay status. Dedicated lay men and women sometimes act as trustees or custodians for their temples, taking part in the financial planning and management of the temple. Others may volunteer significant time in tending to the mundane needs of local monks (by cooking, cleaning, maintaining temple facilities, etc.). Lay activities have traditionally not extended to study of the Pali scriptures, nor the practice of meditation, though in the 20th Century these areas have become more accessible to the lay community, especially in Thailand.
A number of senior monastics in the Thai Forest Tradition, including Buddhadasa, Ajahn Maha Bua, Ajahn Plien Panyapatipo, Ajahn Pasanno, and Ajahn Jayasaro, have begun teaching meditation retreats outside of the monastery for lay disciples.
Ajahn Chah, a disciple of Mun Bhuridatta of the Thai Forest Tradition of the Dhammayuttika Nikaya, set up a monastic lineage called Cittaviveka at Chithurst Buddhist Monastery with his disciple Ajahn Sumedho, at Chithurst in West Sussex, England. Ajahn Sumedho later founded the Amaravati Buddhist Monastery in Hertfordshire, which has a retreat center specifically for lay retreats. Sumedho extended this to Harnham in Northumberland as Aruna Ratanagiri under the present guidance of Ajahn Munindo, another disciple of Ajahn Chah.
Nibb?na, the highest goal of Therav?da Buddhism, is attained through study and the practice of s?la (morality), sam?dhi (meditation) and paññ? (wisdom). The goal of nibb?na and its associated techniques have traditionally been seen as the domain of the fully ordained monastic, whereas many of the same techniques can be used by laypersons to generate happiness in their lives without focusing on nibb?na. Monastic roles in the Theravada school can be broadly described as being split between the role of the (often urban) scholar monk and the (often rural or forest) meditation monk. Both types of monks serve their communities as spiritual teachers and officiants by presiding over spiritual ceremonies and providing instruction in basic Buddhist morality and teachings.
Scholar monks undertake the path of studying and preserving the Pali literature of the Therav?da. They may devote little time to the practice of meditation, but may attain great respect and renown by becoming masters of a particular section of the Pali Canon or its commentaries. Masters of the abhidhamma, called ?bhidhammika, are particularly respected in the scholastic tradition.
Meditation monks, often called forest monks because of their association with certain wilderness-dwelling traditions, are considered to be specialists in meditation. While some forest monks may undertake significant study of the Pali Canon, in general meditation monks are expected to learn primarily from their meditation experiences and personal teachers, and may not know more of the Tipitaka than is necessary to participate in liturgical life and to provide a foundation for fundamental Buddhist teachings. More so than the scholastic tradition, the meditation tradition is associated with the attainment of certain supernatural powers described in both Pali sources and folk tradition. These powers include the attainment of Nirvana, mind-reading, supernatural power over material objects and their own material bodies, seeing and conversing with gods and beings living in hell, and remembering their past lives. These powers are called abhiñña. Sometimes the remain of the cremated bone fragment of an accomplished forest monk is believed able to transform itself into crystal-like relics called sar?ra or dh?tu.
The minimum age for ordaining as a Buddhist monk is 20 years, reckoned from conception. However, boys under that age are allowed to ordain as novices (s?ma?era), performing a ceremony such as shinbyu in Myanmar. Novices shave their heads, wear the yellow robes, and observe the Ten Precepts. Although no specific minimum age for novices is mentioned in the scriptures, traditionally boys as young as seven are accepted. This tradition follows the story of the Buddha's son, Rahula, who was allowed to become a novice at the age of seven. Monks follow 227 rules of discipline, while nuns follow 311 rules.
In most Therav?da countries, it is a common practice for young men to ordain as monks for a fixed period of time. In Thailand and Myanmar, young men typically ordain for the retreat during Vassa, the three-month monsoon season, though shorter or longer periods of ordination are not rare. Traditionally, temporary ordination was even more flexible among Laotians. Once they had undergone their initial ordination as young men, Laotian men were permitted to temporarily ordain again at any time, though married men were expected to seek their wife's permission. Throughout Southeast Asia, there is little stigma attached to leaving the monastic life. Monks regularly leave the robes after acquiring an education, or when compelled by family obligations or ill health.
Ordaining as a monk, even for a short period, is seen as having many virtues. In many Southeast Asian cultures, it is seen as a means for a young man to "repay" his parents for their work and effort in raising him, because the merit from his ordination accrues to them as well. Thai men who have ordained as a monk may be seen as more fit husbands by Thai women, who refer to men who have served as monks with a colloquial term meaning "ripe" to indicate that they are more mature and ready for marriage. Particularly in rural areas, temporary ordination of boys and young men traditionally gave peasant boys an opportunity to gain an education in temple schools without committing to a permanent monastic life.
In Sri Lanka, temporary ordination is not practised, and a monk leaving the order is frowned upon. The continuing influence of the caste system in Sri Lanka plays a role in the taboo against temporary or permanent ordination as a bhikkhu in some orders. Though Sri Lankan orders are often organized along caste lines, men who ordain as monks temporarily pass outside of the conventional caste system, and as such during their time as monks may act (or be treated) in a way that would not be in line with the expected duties and privileges of their caste.
Men and women born in Western countries, who become Buddhists as adults, wish to become monks or nuns. It is possible, and one can live as a monk or nun in the country they were born in, seek monks or nuns which has gathered in a different Western country or move to a monastery in countries like Sri Lanka or Thailand. It is seen as being easier to live a life as a monk or nun in countries where people generally live by the culture of Buddhism, since it is difficult to live by the rules of a monk or a nun in a Western country. For instance; a Therav?da monk or nun is not allowed to work, handle money, listen to music, cook and so on, which are extremely difficult rules to live by in cultures which do not embrace Buddhism.
Some of the more well-known Therav?dan monks are Mun Bhuridatta, Ajahn Chah, Ledi Sayadaw, Ajahn Plien Panyapatipo, Ajahn Sumedho, Ajahn Khemadhammo, Ajahn Brahm, Bhikkhu Bodhi, Buddhadasa, Mahasi Sayadaw, Nyanaponika Thera, Preah Maha Ghosananda, U Pandita, Ajahn Amaro, Ajahn Sucitto, Thanissaro Bhikkhu, Walpola Rahula, Henepola Gunaratana, Bhante Yogavacara Rahula and Luang Pu Sodh Candasaro.
The practices usually vary in different sub-schools and monasteries within Therav?da. But in the most orthodox forest monastery, the monk usually models his practice and lifestyle on that of the Buddha and his first generation of disciples by living close to nature in forest, mountains and caves. Forest monasteries still keep alive the ancient traditions through following the Buddhist monastic code of discipline in all its detail and developing meditation in secluded forests.
In a typical daily routine at the monastery during the 3 month vassa period, the monk will wake up before dawn and will begin the day with group chanting and meditation. At dawn the monks will go out to surrounding villages bare-footed on alms-round and will have the only meal of the day before noon by eating from the bowl by hand. Most of the time is spent on Dhamma study and meditation. Sometimes the abbot or a senior monk will give a Dhamma talk to the visitors. Laity who stay at the monastery will have to abide by the traditional eight Buddhist precepts.
The life of the monk or nun in a community is much more complex than the life of the forest monk. In the Buddhist society of Sri Lanka, most monks spend hours every day in taking care of the needs of lay people such as preaching bana, accepting alms, officiating funerals, teaching dhamma to adults and children in addition to providing social services to the community.
After the end of the Vassa period, many of the monks will go out far away from the monastery to find a remote place (usually in the forest) where they can hang their umbrella tents and where it is suitable for the work of self-development. When they go wandering, they walk barefoot, and go wherever they feel inclined. Only those requisites which are necessary will be carried along. These generally consist of the bowl, the three robes, a bathing cloth, an umbrella tent, a mosquito net, a kettle of water, a water filter, razor, sandals, some small candles, and a candle lantern.
The monks do not fix their times for walking and sitting meditation, for as soon as they are free they just start doing it; nor do they determine for how long they will go on to meditate. Some of them sometimes walk from dusk to dawn whereas at other times they may walk from between two and seven hours. Some may decide to fast for days or stay at dangerous places where ferocious animals live in order to aid their meditation.
Those monks who have been able to achieve a high level of attainment will be able to guide the junior monks and lay Buddhists toward the four degrees of spiritual attainment.
In Pali the word for a male lay devotee is Upasaka. Upasika is its female equivalent. One of the duties of the lay followers, as taught by the Buddha, is to look after the needs of the monk/nuns. They are to see that the monk/nuns do not suffer from lack of the four requisites: food, clothing, shelter and medicine. As neither monks nor nuns are allowed to have an occupation, they depend entirely on the laity for their sustenance. In return for this charity, they are expected to lead exemplary lives.
In Myanmar and Thailand, the monastery was and is still regarded as a seat of learning. In fact today about half of the primary schools in Thailand are located in monasteries. Religious rituals and ceremonies held in a monastery are always accompanied by social activities. In times of crisis, it is to the monks that people bring their problems for counsel.
Traditionally, a ranking monk will deliver a sermon four times a month: when the moon waxes and wanes and the day before the new and full moons. The laity also have a chance to learn meditation from the monks during these times.
It is also possible for a lay disciple to become enlightened. As Bhikkhu Bodhi notes, "The Suttas and commentaries do record a few cases of lay disciples attaining the final goal of Nirvana. However, such disciples either attain Arahantship on the brink of death or enter the monastic order soon after their attainment. They do not continue to dwell at home as Arahant householders, for dwelling at home is incompatible with the state of one who has severed all craving."
Therav?da monks typically belong to a particular nikaya, variously referred to as monastic orders or fraternities. These different orders do not typically develop separate doctrines, but may differ in the manner in which they observe monastic rules. These monastic orders represent lineages of ordination, typically tracing their origin to a particular group of monks that established a new ordination tradition within a particular country or geographic area.
In Sri Lanka caste plays a major role in the division into nikayas. Some Therav?da Buddhist countries appoint or elect a sangharaja, or Supreme Patriarch of the Sangha, as the highest ranking or seniormost monk in a particular area, or from a particular nikaya. The demise of monarchies has resulted in the suspension of these posts in some countries, but patriarchs have continued to be appointed in Thailand. Myanmar and Cambodia ended the practice of appointing a sangharaja for some time, but the position was later restored, though in Cambodia it lapsed again.
