The Buddha's Teachings

As part of our larger collection of world religion overviews, Infoplease is happy to present some of the fundamentals of Buddhism. Learn more about the history of Buddhism, what some of the major Buddhist groups are, and what are some of the core beliefs.


Buddhism was founded in the fourth or fifth century B.C. in northern India by a man known traditionally as Siddhartha Gautama, the son of a warrior prince. Some scholars believe that he lived from 563 to 483 B.C., though his exact life span is uncertain. Troubled by the inevitability of suffering in human life, he left his birthplace in Nepal and a pampered life at the age of 29 to wander as an ascetic, seeking religious insight and a solution to the struggles of human existence. He passed through many trials and practiced extreme self-denial. Finally, while meditating under the bodhi tree (“tree of perfect knowledge”), he reached enlightenment and taught his followers about his new spiritual understanding.

Important Concepts

Buddhist teachings differed from the Hindu faith prevalent in India at the time. Whereas in Hinduism the Brahmin caste alone performed religious functions and attained the highest spiritual understanding, Gautama's beliefs were more egalitarian, accessible to all who wished to be enlightened. At the core of his understanding were the Four Noble Truths: (1) all living beings suffer; (2) the cause of suffering is desire—for material possessions, power, and so on; (3) desire can be overcome; and (4) there is a path that leads to release from desire. This way is called the Noble Eightfold Path, or just the Eightfold Path: right views, right intention, right speech, right action, right livelihood, right effort, right concentration, and right ecstasy.

Gautama promoted the concept of anatman (that a person has no actual self) and the idea that existence is impermanent. This realization helps one let go of desire for transient things. Still, Gautama did not recommend extreme self-denial but rather a disciplined life called the Middle Way. Like the Hindus, he believed that existence consisted of reincarnation, a cycle of rebirth and death. He held that it could be broken only by reaching complete detachment from worldly cares. Then the soul could be released into nirvana (literally “blowing out”)—an indescribable state of total transcendence. Gautama traveled to preach the dharma (sacred truth) and was recognized as the Buddha (enlightened one). After his death his followers continued to develop doctrine and practice, which came to center on the Three Jewels: the dharma (the sacred teachings of Buddhism), the sangha (the community of followers, which now includes buddhist monks, nuns, and laity), and the Buddha. Under the patronage of the Mauryan emperor Ashoka (third century B.C.), Buddhism spread throughout India and to other parts of Asia. Monasteries were established, as well as temples dedicated to Buddha. At shrines, often known as stupas, his relics were venerated. Though by the fourth century A.D. Buddhist presence in India had dwindled, it flourished in other parts of Asia.

Schools of Thought

Numerous Buddhist traditions have emerged. The oldest, called the Theravada (Way of the Elders) tradition, interprets Buddha as a great sage but not a deity. It emphasizes meditation and ritual practices that help the individual become an arhat, an enlightened being. Its followers emphasize the authority of the earliest Buddhist scriptures, the Tripitaka (Three Baskets) or Tipitaka, a compilation of sermons, rules for celibates, and doctrine. The Tripitaka as held by Theravadins is also called the Pali Canon, since it is written in Pali as well as Sanskrit. This tradition is prevalent in Southeast Asia. Thailand, Cambodia, Laos, Myanmar (formerly Burma) and Vietnam--and Sri Lanka. It is sometimes called the Hinayana (Lesser Vehicle) tradition (once considered a pejorative term).

Between the second century B.C. and the second century A.D., the Mahayana (Greater Vehicle) tradition refocused Buddhism to concentrate less on individual attainment of enlightenment and more on concern for humanity. It promotes the ideal of the bodhisattva (enlightened being), who shuns entering nirvana until all sentient beings can do so as well, willingly remaining in the painful cycle of birth and death to perform works of compassion. Members of this tradition conceive of Buddha as an eternal being to whom prayers can be made; other Buddhas are revered as well, adding a polytheistic dimension to the religion. Numerous sects have developed from the Mahayana tradition, which has been influential in China, Korea, and Japan.

A third broad tradition, variously called Vajrayana (Diamond Vehicle), Mantrayana (Vehicle of the Mantra), or Tantric Buddhism, offers a quicker, more demanding way to achieve nirvana. Because of its level of challenge—enabling one to reach enlightenment in one lifetime—it requires the guidance of a spiritual leader. It is most prominent in Tibet and Mongolia. Buddhism as practiced in Tibet is often called simply Tibetan Buddhism. Tibetan Buddhism is most identified with its leader, the Dalai Lama.

Zen Buddhism encourages individuals to seek the Buddha nature within themselves and to practice a disciplined form of sitting meditation in order to reach satori—spiritual enlightenment.

Buddhism is often practiced and learned through knowledge of the different sutras, or suttas.
