“The enneagram is perpetual motion, the same perpetual motion that men have sought since the remotest antiquity and could never find. And it is clear why they could not find perpetual motion. They sought outside themselves that which was within them; and they attempted to construct perpetual motion as a machine is constructed, whereas real perpetual motion is a part of another perpetual motion and cannot be created apart from it. The enneagram is a schematic diagram of perpetual motion, that is, of a machine of eternal movement. But of course it is necessary to know how to read this diagram. The understanding of this symbol and the ability to make use of it give man very great power. It is perpetual motion and it is also the philosopher’s stone of the alchemists.
“The knowledge of the enneagram has for a very long time been preserved in secret and if it now is, so to speak, made available to all, it is only in an incomplete and theoretical form of which nobody could make any practical use without instruction from a man who knows.
“In order to understand the enneagram it must be thought of as in motion, as moving. A motionless enneagram is a dead symbol; the living symbol is in motion.”
