"To 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 - with-
out selfish attachments, and alike in success and defeat. For
yoga is perfect evenness of mind. (2:47-48)
'Fruits,' of course, means the outcome. What Krishna means is to give up attachment to the results of what you do: that is, to give your best to every undertaking without insisting the results workout the way you want, or even what you do is pleasant or unpleasant. 'You have the right to action, but not the fruits of action.': each of us has the obligation to act rightly, but no power to dictate what is to come of what we do."
