THE ESOTERIC THEORY OF BREATH.

The Science of Breath, like many other teachings, has its esoteric or
inner phase, as well as its exoteric or external. The physiological
phase may be termed the outer or exoteric side of the subject, and the
phase which we will now consider may be termed its esoteric or inner

found in all occult teachings and philosophies, and has for centuries
formed a portion of the teachings of the Oriental Yogis.

In order to avoid misconceptions arising from the various theories
regarding this great principle, which theories are usually attached to
some name given the principle, we, in this work, will speak of the
principle as "Prana," this word being the Sanskrit term meaning
"Absolute Energy." Many occult authorities teach that the principle
which the Hindus term "Prana" is the universal principle of energy or
force, and that all energy or force is derived from that principle,
or, rather, is a particular form of manifestation of that principle.
These theories do not concern us in the consideration of the subject
