That courage, O son of Pritha! is good courage, which is unswerving, and by which one controls the operations of the mind, breath, and senses, through abstraction. But, O Arguna! that courage is passionate, by which one adheres to piety, lust, and wealth, and through attachment wishes, O son of Pritha! for the fruit. That courage is dark, O son of Pritha! by which an undiscerning man does not give up sleep, fear, sorrow, despondency, and folly.
