Correspondence to them we are able to understand much that would
otherwise be unknowable to us. This Principle is of universal
application and manifestation, on the various planes of the material,
mental, and spiritual universe--it is an Universal Law. The ancient
Hermetists considered this Principle as one of the most important mental
instruments by which man was able to pry aside the obstacles which hid
from view the Unknown. Its use even tore aside the Veil of Isis to the
extent that a glimpse of the face of the goddess might be caught. Just
as a knowledge of the Principles of Geometry enables man to measure
distant suns and their movements, while seated in his observatory,
so a knowledge of the Principle of Correspondence enables Man to reason
intelligently from the Known to the Unknown. Studying the monad, he
understands the archangel.

3. The Principle of Vibration

"Nothing rests; everything moves; everything vibrates."--The
Kybalion.

This Principle embodies the truth that "everything is in motion";
"everything vibrates"; "nothing is at rest"; facts which Modern Science
endorses, and which each new scientific discovery tends to verify. And
yet this Hermetic Principle was enunciated thousands of years ago, by
the Masters of Ancient Egypt. This Principle explains that the
differences between different manifestations of Matter, Energy, Mind,
and even Spirit, result largely from varying rates of Vibration. From
THE ALL, which is Pure Spirit, down to the grossest form of Matter, all
is in vibration--the higher the vibration, the higher the position in
the scale. The vibration of Spirit is at such an infinite rate of
intensity and rapidity that it is practically at rest--just as a rapidly
