The deeper one penetrates into the Void the more he is purified of the illusions of personality, time, matter, space, and causality. Between the second and third stages of insight's unfoldment there are really two further subsidiary stages which are wrapped in the greatest mystery and are rarely touched by the average mystic or yogi. For both of them are stages which lead further downwards into the Void. The yogi touches the edge of the Void, as it were, but not its centre. These two stages are purificatory ones and utterly annihilate the last illusions and the last egoisms of the seeker. They are dissolved forever and cannot revive again. Nothing more useful can and may be said about it here. For this is the innermost holy of holies, the most sacred sanctuary accessible to man. He who touches this grade touches what may not be spoken aloud for sneering ears, nor written down for sneering eyes. Consequently none has ever ventured to explain publicly what must not be so explained.
