According to Osho, true surrender is not "I becoming His instrument" but the disappearance of the very "I" that wants to surrender. When the ego’s urge to announce or compare drops, no one remains to choose; life simply flows. If you still ask "His will or mine?" the "I" is intact; genuine surrender is quiet, simple, choiceless.
Real letting go means the ‘me’ vanishes and life moves by itself; if you still want to claim you surrendered, you haven’t.
