Patimokkha
The Prātimokṣa (Sanskrit: प्रातिमोक्ष Prātimokṣa; Pali: Pāṭimokkha) is a list of rules (contained within the vinaya) governing the behaviour of Buddhist monks (Bhikkhus) and nuns (Bhikkhunis). Prati means "towards", and mokṣa means liberation from cyclic existence (saṃsāra).
It became customary to recite these rules once a fortnight at a meeting of the sangha during which confession would traditionally take place. A number of prātimokṣa codes are extant, including those contained in the Theravāda Vinaya, Mahāsāṃghika Vinaya, Mahīśāsaka Vinaya, Dharmaguptaka Vinaya, Sarvāstivāda Vinaya, and the Mūlasarvāstivāda Vinaya. Prātimokṣa texts may also circulate in separate prātimokṣa sūtras, which are extracts from their respective vinayas.
