According to Osho, keep making a wholehearted effort with the breath even if, under shaktipat, it seems to stop. The outcome isn't yours; your totality is. Don't heed the mind's fear or excuses; stake yourself completely. Even a tiny holding back can block the breakthrough - the 'last straw' of total effort allows the inner shift to happen, whether or not breath moves.
Don’t quit when the breath pauses—give your full effort; what counts is your total commitment, not whether the breath moves.
