One’s duty is to act, act well, act good; act within the bounds of morality; act in love, continue acting; the consequences will naturally follow as the fruit follows the flower. One need not worry or exult. Act enthusiastically, with faith – success is yours. Activity must result from the awareness of detachment. That is the secret of a happy life.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
