It is not those who lack energy or refrain from action, but those who work without expectation of reward who attain the goal of meditation. Theirs is true renunciation. Therefore, Arjuna, you should understand that renunciation and the performance of selfless service are the same. Those who cannot renounce attachment to the results of their work are far from the path.
-Bhagavad Gita 6:1-2
