According to Osho, direct grace does not come first or partially; it descends only when the ego has completely vanished. Grace is not a means to attainment but the flowering that happens at attainment itself. Since it arrives only with egolessness, its 'effect' is not temporary—it's the very state of realization.
Grace doesn’t push you to the goal; when your ego is gone, grace is what being at the goal feels like.
