十不二門指要鈔 2.48

2.48

初、標。以在纏心變造諸法，一多相礙念念住著，名之為染；以離障心應赴眾緣，一多自在念念捨離，名之為淨。今開在纏一念染心本具三千，俱體俱用與淨不殊，故名不二。有人云，染即是惑，淨即是應。不解文旨，但對而已。須知此門指果後淨用，凡夫染心已具，乃令觀此染心顯於淨用，并後依正俱在能應，自他不二方兼於感。

First, the presentation of the topic. Producing and creating all phenomena with the mind in fetters, wherein the one and the many obstruct each other and there is attachment at every thought-moment, is called defilement. Responding to the multitude of conditions with the mind freed from obstacles, wherein the one and the many are unobstructed and there is relinquishment at every thought-moment, is called purity. Now, opening the single thought-moment of defiled mind in fetters [reveals that] it inherently possesses the three thousand realms; entirely substance and entirely function, it is not different from purity, and hence it is called nondual. Some say that defilement is delusion and purity is response. They do not understand the purport of the text, merely making a parallel contrast. One must realize that this gate points to the pure function after fruition, which the defiled mind of an ordinary person already inherently possesses; it thus causes one to contemplate this defiled mind so as to reveal the pure function. Together with the subsequent environment and body, both reside in the active response; only with the nonduality of self and other does it also encompass the capacity to respond to stimulus.
