5.48

鞞索迦國，周四千餘里。國大都城周十六里。穀稼殷盛，華果具繁。氣序和暢，風俗淳質。好學不倦，求福不回。伽藍二十餘所，僧眾三千餘人，並學小乘正量部法。天祠五十餘所，外道甚多。

This kingdom is about 4000 li in circuit, and the capital about 16 li round. The country produces abundant cereals, and is rich in flowers and fruits. The climate is soft and agreeable. The people are refined and honest; they are very diligent in study, and seek for merit (virtue and good) without relaxation. There are about twenty sangharamas and about 3000 priests, who study the Little Vehicle. to the Sammatiya school. There are about fifty Deva temples and very many heretics.
To the south of the city, on the left of the road, is a large sangharama; this is where the Arhat Devas'arma wrote the Shih-shin-lun (Vijnanakaya S'astra), in which he defends the position that there is no "I" as an individual. The Arhat Gopa (Kiu-po) composed also in this place the Shing-kiau-in-shih-lun, in which he defends the position that there is an "I" as an individual. These doctrines excited much controversial discussion. Again, in this place Dharmapala Bodhisattva during seven days defeated a hundred doctors belonging to the Little Vehicle.
By the side of the sangharama is a stupa about 200 feet high, which was built by As'oka-raja. Here Tathagata in old days preached during six years, and occupied himself whilst so doing in guiding and converting men. By the side of this stupa is a wonderful tree which is 6 or 7 feet high. Through many years it has remained just the same, without increase or decrease. Formerly when Tathagata had cleansed his teeth, he threw away in this place the small piece of twig he had used. It took root, and produced the exuberant foliage which remains to the present time. The heretics and Brahmans have frequently come together and cut it down, but it grows again as before.
Not far from this spot are traces where the four past Buddhas sat and walked. There is also a nail and hair stupa. Sacred buildings here follow one another in succession; the woods, and lakes reflecting their shadows, are seen everywhere.
Going from this north-east 500 li or so, we come to the kingdom of Shi-shih-lo-fu-sih-tai (Sravasti).
