According to Osho, when the "I" existed, life was nothing but mistake; when the ego dissolved, the doer vanished and mistakes became impossible. There is only one real error: the sense of "I." Don’t fix scattered faults; cut the root—ego. In egolessness, actions flow through the Divine, turning even apparent wrongs into right.
All mistakes come from thinking "I am doing it"; let go of that ego and life moves rightly on its own.
