出三藏記集 5.8

5.8

外國僧法學。皆跪而口受。同師所受。若十二十轉。以授後學。若有一字異者。共相推挍。得便擯之。僧法無縱也。經至晉土其年未遠。而憙事者以沙標金。斌斌如也。而無括正。何以別真偽乎。農者禾草俱在。后稷為之嘆息。金匱玉石同緘。卞和為之懷恥。安敢預學次見涇渭雜流龍蛇並進。豈不恥之。今列意謂非佛經者如左。以示將來學士。共知鄙信焉。

In foreign countries, the monastic method of learning is always to kneel and receive instruction orally. Transmitted through teachers for ten or twenty generations to be conferred upon later students, if there is even a single variant character, they investigate and collate it together; once verified, [the error] is discarded. The monastic method allows no laxity. It has not been long since the sūtras arrived in the land of Jin, yet meddlesome individuals mark sand as gold, presenting an elegant surface without any rectification; how could one discern the genuine from the spurious? When weeds and grain grow together for the farmer, Houji sighs in sorrow; when uncut stones are enclosed together in the same coffer as gold, Bian He harbors grief. How could I, Dao'an, daring to be counted among students of learning and seeing the rivers Jing and Wei mingling their streams or dragons and snakes advancing together, not feel shame? Now I set forth those texts which in my estimation are not authentic Buddhist sūtras as follows, in order to show future scholars so that they may jointly know what to disdain and what to trust.
