The mind without delusion is the wholesome opposite of delusion. It is the wisdom that perceives the impermanent, unsatisfactory and soulless nature of conditioned phenomena, perceives the Four Noble Truths, and is able to discern between right and wrong actions.

Greed, anger, delusion and their opposites all have a wide range of intensity from weak to strong. In insight meditation it is important to be aware of whatever is present in the mind no matter how weak or strong it appears to be.
