I mean by the psychic the inmost soul-being and the soul-nature. This is not the sense in which the word is used in ordinary parlance, or rather, if it is so used, it is with great vagueness and much misprision of the true nature of this soul and it is given a wide extension of meaning which carries it far beyond that province. All phenomena of an abnormal or supernormal psychological or an occult character are dubbed psychic; if a man has a double personality changing from one to another, if an apparition of a dying man, something of his mere vital sheath or else a thought form of him, appears and stalks through the room of his wondering friend, if a poltergeist kicks up an Unseemly row in a house, all that is classed under psychic phenomena and regarded as a fit object for psychic re search, though these things have nothing whatever to do with the psychic. Again much in Yoga itself that is merely occult, phenomena of the unseen vital or mental or subtle physical planes, visions, symbols, all that mixed, often perturbed, often shadowy, often illusory range of experiences which belong to this intervening country between the soul and its superficial instruments, or rather to its outermost fringes, all the chaos of the intermediate zone, is summed up as psychic and considered as an inferior and dubious province of spiritual discovery. Again there is a constant confusion between the mentalised desire-soul which is a creation of the vital urge in man, of his life-force seeking for its fulfilment and the true soul which is a spark of the Divine Fire, a portion of the Divine. Because the soul, the psychic being uses the mind and the vital as well as the body as instruments for growth and experience it is  itself looked at as if it were some amalgam or some subtle substratum of mind and life. But in Yoga if we accept all this chaotic mass as soul-stuff or soul-movement we shall enter into a confusion without an issue. All that belongs only to the coverings of the soul; the soul itself is an inner divinity greater than mind or life or body. It is something that once it is released from obscuration by its instruments at once creates a direct contact with the Divine and with the self and spirit.
