2.394

是名入一切諸佛法門　若能深見實相善惡兩。亡應物隨化能善惡。俱遊名悟入法門也。是即或語。或默。或淨。或穢。皆是諸佛化物之門也。

"This is called entering the dharma gates of all Buddhas." If one can deeply see the true mark, both good and evil vanish; responding to beings and following their transformations, one can rove amidst both good and evil—this is called awakening and entering the dharma gates. That is to say, whether speaking or silent, pure or defiled, all are gates through which the Buddhas transform beings.
