If we are afraid of love – and surrender is another word for love – Krsna will bring into our lives the very things we fear will happen if we surrender. So what we fear will happen if we surrender then appears in our lives, because this is what we are focused on and this is what we expect will happen.
But sastra says when we surrender, Krsna takes care of us. If we don’t fully believe this, then He won’t do it. He reciprocates with our mentality; so He will validate our doubts. Thus, fears are self-validating.
