There are three major and progressive goals open to the mystic. The first is to become conscious of the fringe or aura of his divine soul, the Overself. Most mystics, elated by the emotional thrill of its discovery, stop here. The second is to penetrate to its serene centre and pass during trance into the undifferentiated void of its non-sensed, non-thinged essence. The more intelligent and superior mystics, who are naturally much fewer in number than the first kind, are not satisfied until they reach this attainment. It is upon this world-vanishing experience that most Indian yogic metaphysicians base their theory that the universe is an illusion. To the ordinary yogi, this is the summit of achievement and represents for him the goal of human existence. But the trance itself is only temporary. How can a mental self-abstraction, however prolonged, a merely temporary condition, be a final goal for mankind? This is the problem which indeed was stated in The Hidden Teaching Beyond Yoga. All such theories merely show that such mystics have their limitations, however admirable may be their capacity to enter into and sustain the trance state. The third goal is to bring the true self, the essential emptiness and the universal manifestation, into a harmonious, unified experience during full normal wakefulness. This last is philosophical mysticism. Being a complex and complete attainment, it naturally calls for a complex and complete effort. Careful analytical and historical study of mystical practices and mystical biographies will show that it is these three different goals which have always been pursued or achieved, no matter to what external religion, country, or race individual mystics may themselves have belonged. Thus the ordinary mystic's account of the Overself is true but incomplete, his experience of it authentic but insufficient. He has yet to undergo the whole, the complete experience which mysticism can yield. But then, if he does so, if he refuses to remain satisfied with an incomplete and imperfect attainment, he will no longer remain a mystic. He will become a philosopher.
