All stress of egoistic choice, all hankering after personal profit, all stipulation of self-regarding desire must be extirpated from the nature. There must be no demand for fruit and no seeking for reward; the only fruit for you is the pleasure of the Divine Mother and the fulfillment of her work, your only reward a constant progression in divine consciousness and calm and strength and bliss. The joy of service and the joy of inner growth through works is the sufficient recompense of the selfless worker.

(Aurobindo Ghose)
