It is enough that one surrenders oneself. Surrender is giving oneself up to the original cause of one's being. Do not delude yourself by imagining this source to be some God outside you. One's source is within oneself. Give yourself up to it. That means that you should seek the source and merge in it.
Ramana MaharshiAll unhappiness is due to the ego. With it comes all your trouble. If you would deny the ego and scorch it by ignoring it you would be free.
