Vinaya (Skt.; Tib. འདུལ་བ་, dulwa, Wyl. ‘dul ba) — one of the three pitakas or collections of the Buddhist scriptures, concerned primarily with monastic discipline—both its rules and their origin. It is important to note that the Vinaya pitaka also contains a wealth of historical, biographical, and cultural material.
In the Tibetan Kangyur, the Vinaya texts occupy its very first part (Toh 1-7).
