A Community Held Together by Rule, Not by Rank

The sangha traces its founding to the Buddha's first sermon at the deer park in Sarnath, traditionally placed in the fifth century BCE, after which the small circle of early followers grew into an organized order with its own code of discipline, the Vinaya, developed and expanded over the generations that followed and eventually fixed in the Pali canon. What makes the sangha unusual among religious institutions is what it deliberately lacks: no single monk or nun holds authority over the whole body, and no council issues binding rulings for it as a whole.

Cohesion instead comes from a shared text, the Patimokkha, a list of rules that a resident community recites together at fixed points in the lunar month, using the recitation itself as the occasion to confess and settle any breach before it is recited again. Since no central authority ever ruled on doctrine for the whole sangha, disagreements over practice and text produced not a schism managed by a synod but separate transmission lineages that hardened into today's Theravada, Mahayana and Vajrayana streams, each maintaining its own version of the Vinaya and its own reckoning of an unbroken ordination line back toward the historical Buddha, rather than any one of them being declared the sole heir by a decision anyone made.
