Buddhism is a religion originating in the Indian subcontinent and based on teachings attributed to Siddhartha Gautama, known as the Buddha, or “Awakened One.” It encompasses diverse traditions of philosophy, ethical conduct, meditation, devotion, and communal life. Buddhist teachings address suffering and its causes, presenting paths toward awakening and liberation. Beginning with communities of renunciants and householders in ancient India, Buddhism spread across Asia and subsequently developed communities worldwide. (rpl.hds.harvard.edu)
Origins and historical development
The Buddha taught in northern India during the first millennium BCE. His precise dates remain uncertain: traditional chronologies and scholarly estimates differ, with many modern scholars placing his life around the fifth century BCE. Accounts of his life were transmitted and elaborated over centuries; they combine teachings with narratives of renunciation, awakening, and exemplary conduct rather than constituting contemporary biographies.

According to Buddhist tradition, Gautama abandoned a privileged household life, studied with religious teachers, and practiced severe austerities before rejecting both self-indulgence and self-mortification. He attained awakening beneath the Bodhi tree and taught a “Middle Way.” His disciples included monks, nuns, and lay supporters. These communities preserved teachings through oral tradition before their compilation in written collections. (iep.utm.edu)
Royal patronage, particularly that of Ashoka in the third century BCE, supported Buddhism’s expansion. Buddhist communities became established in Sri Lanka and Southeast Asia. Monks traveled through Central Asia along the Silk Road to China during the early centuries CE; Buddhism subsequently developed in Korea and Japan. Its transmission to Tibet drew on Indian Buddhist traditions, including tantric practices. These movements involved adaptation to local languages, institutions, and religious cultures rather than the uniform transplantation of a single system. (pluralism.org)
Principal teachings
The Four Noble Truths provide an influential framework: existence involves dukkha, commonly translated as suffering or unsatisfactoriness; craving and grasping contribute to its arising; its cessation is possible; and a path leads toward that cessation. Dukkha includes physical and mental pain, the instability of pleasurable experiences, and dissatisfaction associated with conditioned existence. The teaching does not simply assert that every experience is painful. (pluralism.org)
The Noble Eightfold Path comprises right view, intention, speech, action, livelihood, effort, mindfulness, and concentration. These mutually supporting practices connect ethics, mental cultivation, and understanding. Liberation is called nirvana: the extinguishing of the conditions that sustain suffering, especially craving, hatred, and delusion. Interpretations of nirvana vary across Buddhist traditions. (pluralism.org)
Other foundational teachings include impermanence, non-self, and dependent origination. Conditioned phenomena change, and persons lack an unchanging, independent essence. Non-self does not mean that persons do not exist conventionally; it challenges identification with a permanent self. Dependent origination explains experience through interrelated causes and conditions. Karma concerns intentional actions and their consequences, while samsara denotes the cycle of birth and death from which liberation is sought. (iep.utm.edu)
Major traditions
Theravada, meaning “Way of the Elders,” is prominent in Sri Lanka, Myanmar, Thailand, Cambodia, and Laos. It accords particular authority to the Pali canon and its commentarial traditions. The arhat, a practitioner who has attained liberation, is an important spiritual ideal. Theravada nevertheless includes varied monastic, devotional, and lay practices rather than a single standardized form. (pluralism.org)
Mahayana, or “Great Vehicle,” emerged within Indian Buddhism around the beginning of the Common Era and developed extensively in East Asia. It emphasizes the bodhisattva path: pursuing awakening for the benefit of all sentient beings. Mahayana recognizes additional scriptures and develops teachings concerning emptiness, compassion, and Buddha-nature. Its traditions include Chan and Zen, Pure Land, and several other schools with differing practices and textual emphases. (pluralism.org)
Vajrayana, meaning “Diamond Vehicle” or “Thunderbolt Vehicle,” developed as an esoteric stream within Mahayana, although it is often presented as a third major tradition. It is especially prominent in Tibet and neighboring regions, with related forms elsewhere in Asia. Its practices include mantras, visualizations, ritual gestures, and mandalas, understood within systems of tantric teaching and transmission. (pluralism.org)
Scriptures and community
Buddhism has no single scriptural collection accepted in identical form by all traditions. The Pali canon, also called the Tipitaka or “Three Baskets,” contains discourses, monastic discipline, and systematic doctrinal analysis. Mahayana traditions recognize further sutras, while Tibetan and East Asian communities preserve extensive translated collections and commentaries. These bodies of literature developed over long periods, making textual history distinct from traditional accounts of their authority. (iep.utm.edu)
Taking refuge in the Three Jewels—the Buddha, Dharma, and Sangha—is a widely shared expression of Buddhist affiliation. Dharma refers especially to the teachings; Sangha can designate the monastic community or, in broader usage, the community of practitioners. Monastics and householders have traditionally maintained reciprocal relationships: laypeople provide material support, while monastics offer teaching and religious services. (pluralism.org)
The Five Precepts concern refraining from killing, stealing, sexual misconduct, false speech, and intoxicants that impair awareness. Monastic discipline adds more extensive rules. Buddhist life also includes meditation, generosity, chanting, offerings, and ritual observances, with their relative importance differing among communities. (pluralism.org)
Artistic and material traditions
Buddhist art gives material expression to teachings, sacred narratives, and devotional practices. Stupas house relics and provide settings for pilgrimage and circumambulation. Images of Buddhas and bodhisattvas developed distinctive regional forms across Asia. Scriptures also shaped book production: a Chinese Diamond Sutra scroll dated 868 CE is an important surviving example of Buddhist woodblock printing. (metmuseum.org)
