BG 2.47-49
Thy business is with the action only, never with its fruits; so let not the fruit of action be thy motive, nor be thou to inaction attached. Perform action, O Dhananjaya, dwelling in union with the divine, renouncing attachments and balanced evenly in success and failure: equilibrium is called yoga. Far lower than the Yoga of Discrimination is action, O Dhananjaya. Take thou refuge in the Pure Reason; pitiable are they who work for fruit.
