This is why the Ankh or "Key of Life" is a sandal-strap, borne in the hand of every God as a mark of his Godhead: a God is one who goes.

Note! Function. For now we see why Tao may also be translated "The Way"; for it is the motion of the structure that we observe. There is no Being apart from Going.
You are familiar with the Four Powers of the Sphinx, attributed by the Adepts of old time to their Four Elements. Air is to Know, Scire; Fire is to Will, Velle; Water is to Dare, Audere; and Earth is to Keep Silence, Tacere. But now that a fifth Element, spirit, is generally recognized in the Qabalah, I have deemed it proper to add a Fifth Power corresponding: to Go, Ire. (Book of Thoth, p. 275)
Then, as Spirit is the Origin, the Essence, and the Sum of the other four, so is to Go in relation to those powers. And to Go is the very meaning of the name God, as elsewhere shewn in these letters; hence the Egyptian Gods were signalized as such by their bearing the Ankh, which is a Sandal-strap, and in its form the Crux Ansata, the Rosy Cross, the means whereby we demonstrate the Godhead of our Nature. See then how sweetly each idea slides into the next! How right this is, that the Quintessence should be dynamic and not static! For if there were some form of Being separate from Going, it would necessarily be subject to decay; and, in any case, a thing impossible to apprehend, since apprehension is itself an Act, not an idea immobile which would be bound to change in the very moment of grasping it.
