Although the Mūlasarvāstivāda-vinaya is only partly extant in Sanskrit, it is known that Guṇaprabha’s Vinayasūtravr̥ttyabhidhānasvavyākhyāna quotes from the Mūlasarvāsti vāda-vinaya many times. Hence, parts of the Sanskrit texts of the Mūlasarvāstivāda vinaya can be recovered by utilizing Guṇaprabha’s Vinayasūtravr̥ttyabhidhānasvavyā khyāna. However, to date the task of editing the Sanskrit text of the Vinayasūtra vr̥ttyabhidhānasvavyākhyāna has only been halfway finished. This paper collects textual passages quoted in Sanskrit manuscripts of the Vinayasūtra vr̥ttyabhidhānasvavyākhyāna and analyzes the text by comparing it with related passages from the Mūlasarvāstivāda-vinaya, and under certain circumstances also the Shisong-lü and Sapoduo-bu pini modeleqie.
