Excavating Sutras: In Search of Ancient Indian Buddhist Scriptures Fumi Yao, Assistant Professor
Sūtras” embedded in the Vinayavastu and the Kṣudrakavastu of the Mūlasarvāstivāda Vinaya
I am working on Buddhist monastic law codes called Vinaya, and especially focus on the Vinaya of a school called Mūlasarvāstivāda, which is said to have once flourished in and around India.
Although each of Indian Buddhist schools seems to have transmitted its canon consisting of three divisions, namely, the Sūtrapiṭaka, the Vinayapiṭaka, and the Abhidharmapiṭaka, only some parts of these schools’ canons are extant. The Mūlasarvāstivāda’s Sūtrapiṭaka is only partially preserved, whereas their Vinayapiṭaka survives in its entirety. Interestingly, there are a considerable number of sūtras, i.e. components of the Sūtrapiṭaka, embedded in this Vinaya. This fact means that even though the majority of the Sūtrapiṭaka no longer exists, we can obtain part of it through a survey of the Vinayapiṭaka.
Today, the Mūlasarvāstivāda Vinaya survives in Sanskrit manuscripts, a Tibetan translation, and a Chinese translation. Through extracting sūtras from these materials and analyzing their relationships with parallel texts and the context of the Vinaya, I would like to clarify what was in the lost Sūtrapiṭaka of the Mūlasarvāstivāda.
