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 that "everything is dual"; "everything
has two poles"; "everything has its pair of opposites," all of which
were old Hermetic axioms. It explains the old paradoxes, that have
perplexed so many, which have been stated as follows: "Thesis and
antithesis are identical in nature, but different in degree"; "opposites
are the same, differing only in degree"; "the pairs of opposites may be
reconciled"; "extremes meet"; "everything is and isn't, at the same
