大唐西域記 1.102

1.102

臥像伽藍東南行二百餘里，度大雪山，東至小川澤，泉池澄鏡，林樹青葱。有僧伽藍，中有佛齒及劫初時獨覺齒，長餘五寸，廣減四寸；復有金輪王齒，長三寸，廣二寸；商諾迦縛娑（舊曰商那和修，訛也）大阿羅漢所持鐵鉢，量可八九升。凡三賢聖遺物，並以黃金緘封。又有商諾迦縛娑九條僧伽胝衣，絳赤色，設諾迦草皮之所績成也。商諾迦縛娑者，阿難弟子也，在先身中，以設諾迦草衣，於解安居日，持施眾僧。承茲福力，於五百身中陰、生陰，恒服此衣。以最後身，從胎俱出，身既漸長，衣亦隨廣；及阿難之度出家也，其衣變為法服；及受具戒，更變為九條僧伽胝。將證寂滅，入邊際定，發智願力，留此袈裟，盡釋迦遺法。法盡之後，方乃變壞。今已少損，信有徵矣。

To the south-west of the convent of the sleeping figure (of Buddha), going 200 li or so, passing the great Snowy Mountains on the east, there is a little watercourse (or valley), which is moist with (the overflowings of) standing springs, bright as mirrors; the herbage here is green and bright. There is a saṅghārāma here with a tooth of Buddha, also the tooth of a Pratyeka Buddha, who lived at the beginning of the Kalpa, which is in length about five inches, and in breadth somewhat less than four inches. Again, there is the tooth of a golden-wheel king, in length three inches, and in surface (breadth) two inches. There is also the iron begging-dish of Sanakavāsa, a great Arhat, which is capable of holding eight or nine shing (pints). These three sacred objects, bequeathed by the holy personages referred to, are all contained in a yellow-golden sealed case. Again, there is here the Sanghati robe, in nine pieces of Sanakavasa; the colour is a deep red (rose-red) ; it is made of the bark (peel) of the She-no-kia plant. Sanakavasa was the disciple of Ananda. In a former existence he had given the priests garments made of the Sanaka plant (fibre), on the conclusion of the rainy season. By the force of this meritorious action during 500 successive births he wore only this (kind of) garment, and at his last birth he was born with it. As his body increased so his robe grew larger, until the time when he was converted by Ananda and left his home (i.e., became an ascetic).

Then his robe changed into a religious garment; and when he was fully ordained it again changed into a Sanghati, composed of nine pieces. When he was about to arrive at Nirvana he entered into the condition of Samadhi, bordering on complete extinction, and by the force of his vow in attaining wisdom (he arrived at the knowledge) that this kashaya garment would last till the bequeathed law (testament) of Sakya (was established), and after the destruction of this law then his garment also would perish. At the present time it is a little fading, for faith also is small at this time ! Going eastward from this, we enter the defiles of the Snowy Mountains, cross over the black ridge (Siah Koh), and arrive at the country of Kia-pi-shi.
