The first of the three “wheels” of the Buddha’s teaching contains the vinaya literature, which treats monastic conduct and institutional life. The eight works here (D.1-D.8) fill thirteen volumes and are arranged according to a system known as the “Four Classes of Vinaya Scripture” (འདུལ་བ་ལུང་སྡེ་བཞི་, ’dul ba lung sde bzhi):
These works were translated from Sanskrit into Tibetan in the ninth century. Taken together, this compendium of monastic instruction is the largest of six extant vinaya collections, and is attributed to the Mūlasarvāstivāda School of Indian Buddhism. It is therefore often referred to as the Mūlasarvāstivāda-vinaya, or the “Monastic Code of the Root Group that Teaches that All Exists.”
