9.210

Answer: The defiled is destroyed accordingly. How is this known to be so? The pure substance belongs to what arises from pure karma; defilement is merely seen superimposed upon the pure. Because the pure is destroyed, the condition for defilement has nothing to perceive—just as pretas originally see fire in the water of the Ganges, but when the water of the Ganges dries up, the pretas do not see fire.
