The Pratimokṣa (Sanskrit: प्रातिमोक्ष, romanized: prātimokṣa) is a list of rules (contained within the vinaya) governing the behaviour of Buddhist monastics (monks or bhikṣus and nuns or bhikṣuṇīs).
A number of prātimokṣa codes are extant, including those contained in the Theravāda, Mahāsāṃghika, Mahīśāsaka, Dharmaguptaka, Sarvāstivāda and Mūlasarvāstivāda vinayas.
The Mūlasarvāstivāda Vinaya is preserved in both the Tibetan Buddhist canon in the Kangyur, in a Chinese edition, and in an incomplete Sanskrit manuscript.
Some other complete Vinaya texts are preserved in the Chinese Buddhist canon (see: Taishō Tripiṭaka), and these include: The Dharmaguptaka sect are known to have rejected the authority of the Sarvāstivāda pratimokṣa rules on the grounds that the original teachings of the Buddha had been lost.
