Nisargadatta MaharajQ: Your words are wise, your behaviour noble, your grace all-powerful.  M: I know nothing about it all and see no difference between you and me. My life is a succession of events, just like yours. Only I am detached and see the passing show as a passing show, while you stick to things and move along with them.
