BG 18.1-3
Arjuna said: I desire, O mighty-armed, to know severally the essence of renunciation, O Hrishîkesha, and of relinquishment, O Keshinishûdana. The Blessed Lord said: Sages have known as renunciation the renouncing of works with desire; the relinquishing of the fruit of all actions is called relinquishment by the wise. "Action should be relinquished as an evil," declare some thoughtful men; "acts of sacrifice, gift and austerity should not be relinquished," say others.
