CHAPTER 18:
KANYAKUBJA, OR CANOUGE. BUDDHA'S PREACHING.

Two Monasteries at Kanyakubja along the Ganges
Faxian stayed at the Dragon vihara till after the summer retreat, and then, travelling to the south-east for seven yojanas, he arrived at the city of Kanyakubja, lying along the Ganges. There are two monasteries in it, the inmates of which are students of the hinayana.
Stupa where the Buddha preached about impermanence
At a distance from the city of six or seven li, on the west, on the northern bank of the Ganges, is a place where Buddha preached the Law to his disciples. It has been handed down that his subjects of discourse were such as "The bitterness and vanity (of life) as impermanent and uncertain," and that "The body is as a bubble or foam on the water." At this spot a tope was erected, and still exists.
Village of A-le
Having crossed the Ganges, and gone south for three yojanas, (the travellers) arrived at a village named A-le, containing places where Buddha preached the Law, where he sat, and where he walked, at all of which topes have been built.
