An eminent disciple of the Buddha famed for his knowledge of monastic law and discipline (Vinaya). A member of the barber clan in the Buddha's home town of Kapilavastu.Upāli sought ordination when the Buddha first returned to see his family after gaining enlightenment (bodhi). As a monk he devoted himself to the study of the monastic rules and held numerous discussions with the Buddha over problematic cases. These questions and answers are recorded in the Parivāra section of the Vinaya Piṭaka. In the First Council held at Rājagṛha.Upāli was called upon to recite the Vinaya, which, according to tradition (almost certainly erroneously), was fixed at that time.
