On Yuan Chwang's Travels in India, 629–645 A.D. v1.c6.s2.15

v1.c6.s2.15

The pilgrim's description proceeds to relate that there were in this country more than 100 Buddhist monasteries with above 5000 Brethren who were adherents of the Sarvāstivādin branch of the "Little Vehicle" and studied the books of their religion in the language of India. These Brethren also were held in the "gradual teaching", and took along with other food the "three pure" kinds of flesh, but they were extremely punctilious in observing the rules of their code of discipline.
