四明尊者教行錄 3.56

3.56

答：大師明通教習氣，凡有二種，謂煩惱障、法障之習氣。法障即界內塵沙也。若留習潤生者，此正為煩惱之習氣耳。以由煩惱是染污無知，無明為體，能招生死故。塵沙是不染污無知，劣慧為體，不招生死故。應云：菩薩為潤生故，須留煩惱之習；為化物故，須破塵沙之習。則知二習其體稍殊。

Answer: The Great Master explains that in the shared teaching there are two kinds of residual traces: the residual traces of the affliction obstacle and those of the phenomena obstacle. The phenomena obstacle is precisely the dust-and-sand within the realms. If one speaks of retaining residual traces to moisten rebirth, this refers precisely to the residual traces of afflictions. This is because afflictions are defiled unknowing, taking fundamental ignorance as their essence, and they can produce birth and death. Dust-and-sand is undefiled unknowing, taking inferior wisdom as its essence, and does not produce birth and death. One should say: in order to moisten rebirth, a bodhisattva must retain the residual traces of affliction; in order to transform beings, he must break through the residual traces of dust-and-sand. Thus one knows that the essences of these two residual traces are somewhat different.
