The Bhagavad Gita

by Krishna-Dwaipayana Vyasa

Desire is the fuel of life; without desire nothing can be achieved, let alone so stupendous a feat as Self-realization. Kama is not desire; it is selfish desire.

You have the right to work, but never to the fruit of work. You should never engage in action for the sake of reward, nor should you long for inaction. Perform work in this world, Arjuna, as a man established within himself – without selfish attachments, and alike in success and defeat. For yoga is perfect evenness of mind. (2:47–48)

As we think, so we become.
