BG 18.25-27
The action undertaken from delusion, without regard to capacity and consequences—loss and injury to others—that is declared to be dark. Liberated from attachment, not egoistic, endued with firmness and confidence, unchanged by success or failure, that actor is called pure. Impassioned, desiring to obtain the fruit of actions, greedy, harmful, impure, moved by joy and sorrow, such an actor is pronounced passionate.
