That, by which one wrongly understands Dharma and Adharma and also what ought to be done and what ought not to be done that intellect, O Arjuna, is Rajasic (passionate).

The understanding by which one knows dharma and adharma, what should and should not be done, in a distorted way, son of Pritha, is rajasic.

Rajasic understanding grasps dharma and its opposite (adharma), and what should and should not be done, but in a distorted way. It is not wholly blind, yet its judgements are bent by desire and agitation. Such a mind can argue persuasively for what suits it. The verse warns that intelligence by itself does not guarantee right judgement; passion can colour reasoning so that a person half-sees the right but still chooses wrongly.
