The Vinaya texts (Pali & Sanskrit: विनय) are texts of the Buddhist canon (Tripitaka) that also contain the rules and precepts for fully ordained monks and nuns of Buddhist Sanghas (community of like-minded sramanas). The precepts were initially developed thirteen years after the Buddha's enlightenment. Three parallel Vinaya school traditions remain in use by modern ordained sanghas: the Theravada (Sri Lanka & Southeast Asia), Mulasarvastivada (Tibetan Buddhism and the Himalayan region) and Dharmaguptaka (Taiwan and East Asian Buddhism). In addition to these three Vinaya traditions, five other Vinaya schools of Indian Buddhism are preserved in Asian canonical manuscripts, including those of the Kāśyapīya, the Mahāsāṃghika, the Mahīśāsaka, the Sammatīya, and the Sarvāstivāda. The word Vinaya is derived from a Sanskrit verb that can mean to lead, take away, train, tame, or guide, or alternately to educate or teach. It is often translated as 'discipline', with Dhamma-vinaya, 'doctrine and discipline', used by the Buddha to refer to his complete teachings, suggesting its integral role in Buddhist practice. According to an origin story prefaced to the Theravada Bhikkhu Suttavibhanga, in the early years of the Buddha's teaching the sangha lived together in harmony with no vinaya, as there was no need, because all of the Buddha's early disciples were highly realized if not fully enlightened. After thirteen years and as the sangha expanded, situations arose which the Buddha and the lay community felt were inappropriate for mendicants. According to Buddhist tradition, the complete Vinaya Piṭaka was recited by Upāli at the First Council shortly after the Buddha's death. All of the known Vinaya texts use the same system of organizing rules and contain the same sections, leading scholars to believe that the fundamental organization of the Vinaya must date from before the separation of schools. While traditional accounts fix the origins of the Vinaya during the lifetime of the Buddha, all of the existing manuscript traditions are from significantly later- most around the 5th century CE.
