"Muhammad of Arabia ascended the highest Heaven and returned. I swear by God that if I had reached that point, I should never have returned." These are the words of a great Muslim saint, 'AbdulQuddës of Gangoh. In the whole range of Sufi literature it will be probably difficult to find words which, in a single sentence, disclose such an acute perception of the psychological difference between the prophetic and the mystic types of consciousness. The mystic does not wish to return from the repose of "unitary experience"; and even when he does return, as he must, his return does not mean much for mankind at large.
