" begin with, Krishna often tells Arjuna to “renounce the fruits of action” (karma-phala): 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) "
