When we are practicing, we do not think of either good or evil. As soon as any mental state arises, we rest; when meeting with conditions, we rest. The ancients said:

Be like a strip of unbleached silk cloth.
Be like cool, clear water,
Be like an incense burner in an old shrine.
Then you can cut through the spool of silk
And leave behind all discrimination.

This is the method of extinguishing delusion through rest.
