Rh 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. Man's only physical salvation is to "get back to Nature."
