4.51

大城側故伽藍中，有窣堵波，無憂王之所建也，高二百餘尺。如來在昔，於此一月說諸法要，傍有過去四佛座及經行遺迹處。其側有如來髮、爪二窣堵波，各高一丈餘。

This kingdom is about 2000 li in circuit, and the capital about 14 or 15 li. It is naturally strong, being fenced in with crags and precipices. The population is numerous. We find on every side flowers, and groves, and lakes succeeding each other in regular order. The climate and the products resemble those of Ma-ti-pu-lo. The manners of the people are pure and honest. are diligent in study and given to good works. There are many believers in false doctrine, who seek present happiness only. There are two sanghārāmas and about 100 priests, who mostly study the Little Vehicle. There are thirty Deva temples with different sectaries, who congregate together without distinction.
Beside the chief town is an old sanghārāma in which is a stūpa built by King Asōka. It is about 200 feet high; here Buddha, when living, preached for a month on the most essential points of religion. By the side is a place where there are traces of the four past Buddhas, who sat and walked here. At the side of this place are two small stūpas containing the hair and nail-parings of Tathāgata. They are about 10 feet high.
Going from this south-east about 400 li, we come to the country of 'O-hi-chi-ta-lo (Ahikshetra).
