O my Son, learn this concerning Magick, that the Yang moveth, and thus giveth itself up Eternally; but the Yin moveth not, seeking ever to enclose or restrict, reproducing in its own likeness what Impressions soever it made thereon, yet without Surrender. Now the Tao absorbeth all without Reproduction; so then let the Yang turn thereto, and not unto the Yin. And that thou mayst understand this, I say: It is a Mystery of O.T.O. For the Sun ariseth not and entereth to strike upon the High Altar of the Minster by the Great Western Gates, but by the Rose Oriel doth he make Way and Progress in His Pageant. O my Son, the Doors of Silver are wide open, and they tempt thee with their Beauty: but by the narrow Portal of Pure Gold shalt thou come nobly to thy Sanctuary. Behold! Thou knowest not how perfect is this Magick; it is the dearest-bought and holiest of our Arcana. What then is like unto my Love toward Thee, that bestoweth upon thee this Treasure of my Wisdom? My Son, neglect it not; for it is the Exorcism of Exorcisms, and the Enchantment of Enchantments.
