The Noble Mahāyāna Sūtra “Determining the Vinaya: Upāli’s Questions”

Determining the Vinaya: Upāli’s Questions is a sūtra focused on the relationship between and integration of the prātimokṣa vows of monastic discipline and the conduct of a bodhisattva who follows the Mahāyāna tradition. The sūtra’s two main interlocutors, Śāriputra and Upāli, query the Buddha about the relationship between these two levels of commitments, eliciting a teaching on the different orientations held by the followers of different Buddhist vehicles and how their different views affect the application of their vows. Determining the Vinaya is a particularly valuable sūtra for its inclusion of a unique form of the confessional “Three Sections” rite, making it one of the few extant canonical sources to describe it at length.
