Upali

Upāli (Sanskrit and Pāli) was a monk, one of the ten chief disciples of the Buddha and, according to early Buddhist texts, the person in charge of the reciting and reviewing of monastic discipline (Pāli and ) on the First Buddhist Council. Upāli belongs to the barber community. He met the Buddha when still a child, and later, when the Sakya princes received ordination, he did so as well. He was ordained before the princes, putting humility before caste. Having been ordained, Upāli learnt both Buddhist doctrine (; ) and vinaya. His preceptor was Kappitaka. Upāli became known for his mastery and strictness of vinaya and was consulted often about vinaya matters. A notable case he decided was that of the monk Ajjuka, who was accused of partisanship in a conflict about real estate. During the First Council, Upāli received the important role of reciting the vinaya, for which he is mostly known.

Scholars have analyzed Upāli's role and that of other disciples in the early texts, and it has been suggested that his role in the texts was emphasized during a period of compiling that stressed monastic discipline, during which Mahākassapa () and Upāli became the most important disciples. Later, Upāli and his pupils became known as vinayadharas (Pāli; 'custodians of the vinaya'), who preserved the monastic discipline after the Buddha's parinibbāna (; passing into final Nirvana). This lineage became an important part of the identity of Ceylonese and Burmese Buddhism. In China, the 7th-century Vinaya school referred to Upāli as their patriarch, and it was believed that one of their founders was a reincarnation of him. The technical conversations about vinaya between the Buddha and Upāli were recorded in the Pāli and Sarvāstivāda traditions and have been suggested as an important subject of study for modern-day ethics in American Buddhism.
