Vinayaviniścayopāliparipṛcchā

Vinaya-viniścayopāli-paripṛcchā (T. ’dul ba rnam par gtan la dbab pa nye bar ’khor gyis zhus pa; C. 大寶積經淨居天子會第四), or Determining the Vinaya: Upāli’s Questions, is a Mahayana sutra from the Ratnakuta collection that explores the relationship between the prātimokṣa vows and the conduct of a bodhisattva.

The UCSB Buddhist Studies Translation Group states:

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.

And also:

There are several extant Sanskrit witnesses for portions of this sūtra: a lengthy citation drawn from the sūtra’s second section is preserved in the Bodhisattvaprātimokṣa Sūtra, which was studied and reproduced by Nalinaksha Dutt in 1931, and verses from [this text] are cited by Śāntideva in his Śikṣāsamuccaya and by Candrakīrti in the Prasannapadā. [...] Chinese translations of the whole or part of the text can be found in the Chinese Buddhist Canon (Taishō 310, 325, and 326).
