On Yuan Chwang's Travels in India, 629–645 A.D. v1.c14.39

v1.c14.39

To the north-west of the capital was an Asoka tope where the Buddha had preached excellent doctrines for seven days; beside it was a tope where the Four Past Buddhas had sat and walked for exercise; and there was a small tope over hair- and nail-relics of the Buddha. South of the Preaching Tope and close to the Ganges were three Buddhist monasteries enclosed by a common wall but each having its own gate. These vihāras had beautiful images, the Brethren were grave and reverend, and there were thousands of lay Buddhists to serve them. The shrine or temple (ching-she) of the three-fold vihāra had a casket containing a wonder-working tooth of the Buddha an inch and a half long, which was exhibited to crowds of visitors for a charge of one gold coin each. There were other sacred Buddhist buildings near the city, and there were also splendid temples to the Sun-god and to Maheśvara respectively.
