 Buddhism, like the other religious traditions surveyed in this entry, encompasses many views and practices. The principal forms of Buddhism that exist today are Theravāda and Mahāyāna. (Vajrayāna, the tantric tradition of Buddhism, is also sometimes seen as a distinct form.) Theravāda is the dominant form of Buddhism of Sri Lanka and Southeast Asia. It traditionally refers to monastic and textual lineages associated with the study of the Pāli Buddhist Canon. Mahāyāna refers to a movement that likely began roughly four centuries after the Buddha’s death; it became the dominant form of Buddhism in East and Central Asia. It includes Chan or Zen, and also tantric Buddhism, which today is found mostly in Tibet, though East Asian forms also exist.
