We may now perceive a further reason why all great teachers have enjoined self-denial. For at this crucial point of perfected concentration, when the senses are still and the world without remote, the mystic must renounce his thoughts in favour of Thought. He can do this only by a final act of surrender whereby his whole sense of personality--all that makes up what he believed to be "I"--is let go as the last of his thoughts to vanish into a Void. He must make the abrupt leap into self-identification with the wide pure impersonal thought-less Thought. He must give up the last of all thoughts--which is the "I" thought--and accept in return whatever may come to him out of the great Unknown. A fear rises up and overcomes him for a time that with this leap he may so endanger his own existence as to plunge into utter annihilation. This naturally makes him cling all the more to his sense of personality. Shall we wonder then, that every student shrinks at this order?
