首楞嚴義疏注經 4.427

4.427

"Just like clearing turbid water by storing it in a quiet vessel: when quiet, deep, and motionless, the sand and earth spontaneously settle, and the clear water appears before you; this is called initially subduing the adventitious afflictions. Removing the mud and leaving pure water is called permanently severing fundamental avidyā. When the appearance of brightness is pure and refined, none of the myriad transformations and manifestations constitute afflictions; all accord with the pure, wondrous virtues of nirvāṇa."
