大唐西域記 7.13

7.13

釋迦菩薩受記南不遠，有過去四佛經行遺迹，長五十餘步，高可七尺，以青石積成，上作如來經行之像，像形傑異，威嚴肅然，肉髻之上特出鬚髮，靈相無隱，神鑒有徵。於其垣內，聖迹寔多，諸精舍、窣堵波數百餘所，略舉二三難用詳述。

Not far to the south of this spot are traces where the four Buddhas of a bygone age walked for exercise. The length (of the promenade) is about fifty paces and the height of the steps (stepping spots) about seven feet. It is composed of blue stones piled together. Above it is a figure of Tathagata in the attitude of walking. It is of a singular dignity and beauty. From the flesh-knot on the top of the head there flows wonderfully a braid of hair. Spiritual signs are plainly manifested and divine prodigies wrought with power (fineness, éclat). Within the precincts of the enclosure (of the sangharama) there are many sacred vestiges, with viharas and stupas several hundred in number. We have only named two or three of these, as it would be difficult to enter into details. To the west of the sangharama enclosure is a clear lake of water about 200 paces in circuit; here Tathagata occasionally bathed himself. To the west of this is a great tank about 180 paces round; here Tathagata used to wash his begging-dish. To the north of this is a lake about 150 paces round. Here Tathagata used to wash his robes. In each of these pools is a dragon who dwells within it. The water is deep and its taste sweet; it is pure and resplendent in appearance, and neither increases nor decreases. When men of a bad character bathe here, the crocodiles (kin-pi-lo, — kumbhiras) come forth and kill many of them; but in case of the reverential who wash here, they need fear nothing.
