華嚴經義海百門 1.134

1.134

二、辨染淨者，謂見塵生滅有無，是染；即體不生不滅、非有非無，是淨。若空異於有，則淨不名淨，以迷空故；若有異於空，則染不名染，以執有故。今有即全空，方名染分；空即全有，方名淨分。由空有無礙，是故染淨自在也。經云「染而不染，不染而染。」

Second, distinguishing defilement and purity: seeing the arising, cessation, existence, and non-existence of the dust mote is defilement; its essence being unarisen, unceasing, neither existing nor non-existing is purity. If emptiness were different from existence, then purity could not be called purity, because of delusion regarding emptiness; if existence were different from emptiness, then defilement could not be called defilement, because of grasping onto existence. Now, existence is entirely emptiness, which is then called the defiled aspect; emptiness is entirely existence, which is then called the pure aspect. Because emptiness and existence are unobstructed, defilement and purity are completely unhindered. A sūtra states: "Defiled and yet not defiled; undefiled and yet defiled."
