Swami Mukundananda
How can I do my duty without being disturbed by the result?
Do your duty, leave the fruit to God
Accept God's will as your own, do your duty, and leave the fruit in God's hands. The devotee who accepts whatever result comes is not disturbed, and Shri Krishna calls such a devotee dear.
Through surrender you accept God's will as your own, do your duty, leave the fruit in God's hands, and accept whatever fruit God gives. Such a devotee is not disturbed.
