further weakened. Every particle of food and drink must be oxygenated
before it can yield us the proper nourishment, and before the waste
products of the system can be reduced to the proper condition to be
eliminated from the system. Lack of sufficient oxygen means Imperfect
nutrition, Imperfect elimination and imperfect health. Verily, "breath
is life."

The combustion arising from the change in the waste products generates
heat and equalizes the temperature of the body. Good breathers are not
apt to "take cold," and they generally have plenty of good warm blood
which enables them to resist the changes in the outer temperature.

In addition to the above-mentioned important processes the act of
breathing gives exercise to the internal organs and muscles, which
feature is generally overlooked by the Western writers on the subject,
but which the Yogis fully appreciate.

In imperfect or shallow breathing, only a portion of the lung cells
are brought into play, and a great portion of the lung capacity is
lost, the system suffering in proportion to the amount of
under-oxygenation. The lower animals, in their native state, breathe
naturally, and primitive man undoubtedly did the same. The abnormal
manner of living adopted by civilized man--the shadow that follows
upon civilization--has robbed us of our natural habit of breathing,
and the race has greatly suffered thereby. Han's only physical
salvation is to "get back to Nature."
