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
moving wheel seems to be motionless. And at the other end of the scale,
there are gross forms of matter whose vibrations are so low as to seem
at rest. Between these poles, there are millions upon millions of
varying degrees of vibration. From corpuscle and electron, atom and
molecule, to worlds and universes, everything is in vibratory motion.
This is also true on the planes of energy and force (which are but
varying degrees of vibration); and also on the mental planes (whose
states depend upon vibrations); and even on to the spiritual planes.
An understanding of this Principle, with the appropriate formulas,
enables Hermetic students to control their own mental vibrations as well
as those of others. The Masters also apply this Principle to the
conquering of Natural phenomena, in various ways. "He who understands
the Principle of Vibration, has grasped the scepter of power," says one
of the old writers.

4. The Principle of Polarity

"Everything is Dual; everything has poles; everything has its
pair of opposites; like and unlike are the same; opposites are
identical in nature, but different in degree; extremes meet;
all truths are but half-truths; all paradoxes may be
reconciled."--The Kybalion.

This Principle embodies the truth th
