Four Powers of the Sphinx

” Thou canst by no means interpret the Sphinx in Terms of the Formula of the Slain God.
….
But the Light of the New Aeon revealeth this Sphinx as the true Symbol of this our Holy Art of Magick under the Law of Thelema. In Her is the equal Development and Disposition of the Forces of Nature, each in its Balanced Strength; also Her True Name is Soul of NU, having the Digamma for Phi, and endeth in Upsilon, not in Xi, so that Her Orthography is ΣΦΙΝΨ whose Numeration is Six Hundred and Three Score and Six.”
– Liber Aleph, DE SPHINGE AEGYPTIORUM

“See now our Sphinx, with what Subtility and Art is She made Whole!
Here is thy Light, the Lion, the Necessity of thy Nature, fortified by thy Life, the Bull, the Power of Work, and guided by thy Liberty, the Man, the Wit to adapt Action to Environment. These are three Virtues in One, necessary to all proper Motion, as I may say in a Figure, the Lust of the Archer, the propulsive Force of his Arm, and the equilibrating and directing Control of his Eye. Of these three if one fail, the Mark is not hit. But hold! Is not a Fourth Element essential in the Work? Yea, soothly, all were vain without the Engine, Arrow and Bow. This Engine is thy Body, possessed by thee and used by thee for thy Work, yet not Part of thee, even so as are his Weapons to this Archer in my Similitude.”
– Liber Aleph, DE QUATTUOR VIRTUTIS ΣΦΙΝΨ
