The Mahabharata of Krishna-Dwaipayana Vyasa, Volume 2 Books 4, 5, 6 and 7 Quotes

“Some declare that action should be shunned and that salvation is attainable by knowledge. The Brahmanas say that though one may have a knowledge of eatable things, yet his hunger will not be appeased unless he actually eats. Those branches of knowledge that help the doing of work, bear fruit, but not other kinds, for the fruit of work is of ocular demonstration. A thirsty person drinks water, and by that act his thirst is allayed. This result proceeds, no doubt, from work. Therein lies the efficacy of work. If anyone thinks that something else is better than work, I deem, his work and his words are meaningless.”
