Tibetan Buddhist canon
A third influence was that of the Sarvāstivādins from Kashmir to the southwest and Khotan to the northwest. Although they did not succeed in maintaining a presence in Tibet, their texts found their way into the Tibetan Buddhist canon, providing the Tibetans with almost all of their primary sources about what they regarded to be the Hinayana. A subsect of this school, Mūlasarvāstivāda was the source of the Tibetan vinaya.
