ted to Courage and
similar positive mental states. A little study will show you that these
mental changes are nearly all along the line of Polarization, the change
being one of degree rather than of kind.

A knowledge of the existence of this great Hermetic Principle will
enable the student to better understand his own mental states, and those
of other people. He will see that these states are all matters of
degree, and seeing thus, he will be able to raise or lower the vibration
at will--to change his mental poles, and thus be Master of his mental
states, instead of being their servant and slave. And by his knowledge
he will be able to aid his fellows intelligently and by the appropriate
methods change the polarity when the same is desirable. We advise all
students to familiarize themselves with this Principle of Polarity, for
a correct understanding of the same will throw light on many difficult
subjects.

CHAPTER XI

RHYTHM

"Everything flows out and in; everything has its tides;
all things rise and fall; the pendulum-swing manifests
in everything; the measure of the swing to the right,
is the measure of the swing to the left; rhythm
compensates"--The Kybalion.

The great Fifth Hermetic Principle--the Principle of Rhythm-embodies the
truth that in everything there is manifested a measured motion; a
to-and-from movement; a flow and inflow; a swing forward and backward; a
pendulum-like movement; a tide-like ebb and flow; a high-tide and a low-
tide; between the two-poles manifest on the physical, mental or
spiritual planes. The Principle of rhythm is closely connected with the
Principle of Polarity described in the preceding chapter. Rhythm
manifests between the two poles established by the Principle of
Polarity. This does not mean, however, that the pendulum of Rhythm
swings to the extreme poles, for this rarely happens; in fact, it is
difficult to establish the extreme polar opposites in the majority of
cases. But the swing is ever "toward" first one pole and then the other.

There is always an action and reaction; an advance and a retreat; a
rising and a sinking; manifested in all of the airs and phenomena of the
Universe. Suns, worlds, men, animals, plants, minerals, forces, energy,
mind and matter, yes, even Spirit, manifests this Principle. The
Principle manifests in the creation and destruction of worlds; in the
rise and fall of nations; in the life history of all things; and fina
