The goal of Mahayana's bodhisattva path is Samyaksambuddhahood, so that one may benefit all sentient beings by teaching them the path of cessation of dukkha. Mahayana theory contrasts this with the goal of the Theravada path, where the goal is individual arhatship.
In Theravada Buddhism, Buddha refers to one who has become awakened through their own efforts and insight, without a teacher to point out the dharma (Sanskrit; Pali dhamma; "right way of living"). A samyaksambuddha teaches the dharma to others after his awakening. A pratyekabuddha also reaches Nirvana through his own efforts, but does not teach the dharma to others. An arhat needs to follow the teaching of a Buddha to attain Nirvana, but can also preach the dharma after attaining Nirvana. In one instance the term buddha is also used in Theravada to refer to all who attain Nirvana, using the term S?vakabuddha to designate an arhat, someone who depends on the teachings of a Buddha to attain Nirvana. In this broader sense it is equivalent to the arhat.
There is a broad spectrum of opinion on the universality and method of attainment of Buddhahood, depending on Gautama Buddha's teachings that a school of Buddhism emphasizes. The level to which this manifestation requires ascetic practices varies from none at all to an absolute requirement, dependent on doctrine. Mahayana Buddhism emphasizes the bodhisattva ideal instead of the Arhat.
The Tathagatagarba and Buddha-nature doctrines of Mahayana Buddhism consider Buddhahood to be a universal and innate property of absolute wisdom. This wisdom is revealed in a person's current lifetime through Buddhist practice, without any specific relinquishment of pleasures or "earthly desires".
Buddhists do not consider Gautama to have been the only Buddha. The P?li Canon refers to many previous ones (see list of the named Buddhas), while the Mahayana tradition additionally has many Buddhas of celestial origin (see Amit?bha or Vairocana as examples, for lists of many thousands of Buddha names (see Taish? Tripi?aka numbers 439-448).
The various Buddhist schools hold some varying interpretations on the nature of Buddha (see below).
All Buddhist traditions hold that a Buddha is fully awakened and has completely purified his mind of the three poisons of craving, aversion and ignorance. A Buddha is no longer bound by sa?s?ra, and has ended the suffering which unawakened people experience in life.
Some Buddhists meditate on (or contemplate) the Buddha as having ten characteristics (Ch./Jp. ). These characteristics are frequently mentioned in the P?li Canon as well as Mahayana teachings, and are chanted daily in many Buddhist monasteries:
The tenth epithet is sometimes listed as "The World Honored Enlightened One" (Skt. Buddha-Lokanatha) or "The Blessed Enlightened One" (Skt. Buddha-Bhagavan).
In the P?li Canon, Gautama Buddha is known as being a "teacher of the gods and humans", superior to both the gods and humans in the sense of having nirvana or the greatest bliss, whereas the devas, or gods, are still subject to anger, fear and sorrow.
In the Madhupindika Sutta (MN 18), Buddha is described in powerful terms as the Lord of the Dhamma (Pali: Dhammasami, skt.: Dharma Swami) and the bestower of immortality (Pali: Amatassadata).
Similarly, in the Anuradha Sutta (SN 44.2) Buddha is described as
the Tathagata--the supreme man, the superlative man, attainer of the superlative attainment.
[Buddha is asked about what happens to the Tathagatha after death of the physical body. Buddha replies],
"And so, Anuradha--when you can't pin down the Tathagata as a truth or reality even in the present life--is it proper for you to declare, 'Friends, the Tathagata--the supreme man, the superlative man, attainer of the superlative attainment--being described, is described otherwise than with these four positions: The Tathagata exists after death, does not exist after death, both does & does not exist after death, neither exists nor does not exist after death'?
In the Vakkali Sutta (SN 22.87) Buddha identifies himself with the Dhamma:
O Vakkali, whoever sees the Dhamma, sees me [the Buddha]
O Vasettha! The Word of Dhammakaya is indeed the name of the Tathagata
Shravasti Dhammika, a Theravada monk, writes:
In the centuries after his final Nibb?na it sometimes got to the stage that the legends and myths obscured the very real human being behind them and the Buddha came to be looked upon as a god. Actually, the Buddha was a human being, not a 'mere human being' as is sometimes said but a special class of human called a 'complete person' (mah?parisa). Such complete persons are born no different from others and indeed they physically remain quite ordinary.
Sangharakshita also states that "The first thing we have to understand - and this is very important - is that the Buddha is a human being. But a special kind of human being, in fact the highest kind, so far as we know."
When asked whether he was a deva or a human, he replied that he had eliminated the deep-rooted unconscious traits that would make him either one, and should instead be called a Buddha; one who had grown up in the world but had now gone beyond it, as a lotus grows from the water but blossoms above it, unsoiled.
Andrew Skilton writes that the Buddha was never historically regarded by Buddhist traditions as being merely human:
It is important to stress that, despite modern Theravada teachings to the contrary (often a sop to skeptical Western pupils), he was never seen as being merely human. For instance, he is often described as having the thirty-two major and eighty minor marks or signs of a mah?puru?a, "superman"; the Buddha himself denied that he was either a man or a god; and in the Mah?parinibb?na Sutta he states that he could live for an aeon were he asked to do so.
Jack Maguire writes that Buddha is inspirational based on his humanness.
A fundamental part of Buddhism's appeal to billions of people over the past two and a half millennia is the fact that the central figure, commonly referred to by the title "Buddha", was not a god, or a special kind of spiritual being, or even a prophet or an emissary of one. On the contrary, he was a human being like the rest of us who quite simply woke up to full aliveness.
In the early Buddhist schools, the Mah?sghika branch regarded the buddhas as being characterized primarily by their supramundane nature. The Mah?sghikas advocated the transcendental and supramundane nature of the buddhas and bodhisattvas, and the fallibility of arhats. Of the 48 special theses attributed by the Samayabhedoparacanacakra to the Mah?sghika Ekavy?vah?rika, Lokottarav?da, and the Kukku?ika, 20 points concern the supramundane nature of buddhas and bodhisattvas. According to the Samayabhedoparacanacakra, these four groups held that the Buddha is able to know all dharmas in a single moment of the mind. Yao Zhihua writes:
In their view, the Buddha is equipped with the following supernatural qualities: transcendence (lokottara), lack of defilements, all of his utterances preaching his teaching, expounding all his teachings in a single utterance, all of his sayings being true, his physical body being limitless, his power (prabh?va) being limitless, the length of his life being limitless, never tiring of enlightening sentient beings and awakening pure faith in them, having no sleep or dreams, no pause in answering a question, and always in meditation (sam?dhi).
A doctrine ascribed to the Mah?sghikas is, "The power of the tath?gatas is unlimited, and the life of the buddhas is unlimited." According to Guang Xing, two main aspects of the Buddha can be seen in Mah?sghika teachings: the true Buddha who is omniscient and omnipotent, and the manifested forms through which he liberates sentient beings through skillful means. For the Mah?sa?ghikas, the historical Gautama Buddha was one of these transformation bodies (Skt. nirmak?ya), while the essential real Buddha is equated with the Dharmak?ya.
As in Mah?y?na traditions, the Mah?sghikas held the doctrine of the existence of many contemporaneous buddhas throughout the ten directions. In the Mah?sghika Lok?nuvartana S?tra, it is stated, "The Buddha knows all the dharmas of the countless buddhas of the ten directions." It is also stated, "All buddhas have one body, the body of the Dharma." The concept of many bodhisattvas simultaneously working toward buddhahood is also found among the Mah?sghika tradition, and further evidence of this is given in the Samayabhedoparacanacakra, which describes the doctrines of the Mah?sghikas.
Buddhas are frequently represented in the form of statues and paintings. Commonly seen designs include:
The Buddha statue shown calling for rain is a pose common in Laos.
Most depictions of Buddha contain a certain number of markings, which are considered the signs of his enlightenment. These signs vary regionally, but two are common:
In the P?li Canon, there is frequent mention of a list of thirty-two physical characteristics of the Buddha.
The poses and hand-gestures of these statues, known respectively as asanas and mudras, are significant to their overall meaning. The popularity of any particular mudra or asana tends to be region-specific, such as the Vajra (or Chi Ken-in) mudra, which is popular in Japan and Korea but rarely seen in India. Others are more common; for example, the Varada (Wish Granting) mudra is common among standing statues of the Buddha, particularly when coupled with the Abhaya (Fearlessness and Protection) mudra.

Originally every Buddha had ten thousand names. In time these ten thousand names were reduced to one thousand because people got confused trying to remember them all. For a while every Buddha had a thousand names, but people still couldn't remember so many, so they were again reduced to one hundred names. Every Buddha had a hundred different names and living beings had a hard time remembering them, so they were shortened again to ten.
