上善菩薩曰。身口意業為二。是三業皆無作相。身無作相即口無作相。口無作相即意無作相。是三業無作相即一切法無作相。能如是隨無作惠者。是為入不二法門　肇曰。三業雖殊無作一也。諸法之生本乎三業。三業既無誰作諸法。

The Bodhisattva Suviśuddha said, "The actions of body, speech, and mind constitute duality. These three karmas all have the mark of non-action. The body having the mark of non-action means speech has the mark of non-action; speech having the mark of non-action means mind has the mark of non-action. The three karmas having the mark of non-action means all dharmas have the mark of non-action. Being able to accord with such wisdom of non-action is entering the dharma gate of non-duality."
Sengzhao says, "Although the three karmas differ, their non-action is one. The arising of all dharmas is rooted in the three karmas; since the three karmas do not exist, who creates all dharmas?"
