大唐西域記 2.39

2.39

影窟門外有二方石，其一石上有如來足蹈之迹，輪相微現，光明時燭。影窟左右多諸石室，皆是如來諸聖弟子入定之處。影窟西北隅有窣堵波，是如來經行之處。其側窣堵波有如來髮、爪。隣此不遠有窣堵波，是如來顯暢真宗，說蘊界處之所也。影窟西有大盤石，如來甞於其上濯浣袈裟，文影微現。

Tathagata replied, "When I am about to die; I will leave you my shadow, and I will send five Arhats to receive from you continual offerings. When the true law is destroyed, this service of yours shall still go on ; if an evil heart rises in you, you must look at my shadow, and because of its power of love and virtue your evil purpose will be stopped. The Buddhas who will appear throughout this Bhadra-kalpa will all, from a motive of pity, intrust to you their shadows as a bequest." Outside the gate of the Cavern of the Shadow there are two square stones; on one is the impression of the foot of Tathagata, with a wheel-circle (lun-siang) beautifully clear, which shines with a brilliant light from time to time. On either side of the Cavern of the Shadow there are several stone chambers; in these the holy disciples of Tathagata reposed in meditation. At the north-west corner of the cave of the shadow is a stupa where Buddha walked up and down. Beside this is a stupa which contains some of the hair and the nail-parings of Tathagata. Not far from this is a stupa where Tathagata, making manifest the secret principles of his true doctrine, declared the Skandha-dhatu-ayatanas (Yun-kiai-king). At the west of the Cave of the Shadow is a vast rock, on which Tathagata in old time spread out his kashaya robe after washing it; the marks of the tissue still exist.
