First published in 1903, 'The Hindu-Yogi Science of Breath' by William Walker Atkinson, an attorney, merchant, publisher, and author, as well as an occultist and an American pioneer of the New Thought movement.

Yogi's system of Complete Breathing is of vital importance to every man, woman, and child who wishes to acquire health and keep it. This book explains in layman's terms what happens inside our bodies when we inhale and then exhale. And the effects improper breathing has on both our internal and external extremities. It describes nature's proximity to the respiratory and circulatory systems. The final sections include invaluable Yogi breathing exercises for increased breathing awareness and better health.

"All is in vibration. From the tiniest atom to the greatest sun, everything is in a state of vibration. There is nothing in absolute rest in nature. A single atom deprived of vibration would wreck the universe. In incessant vibration, the universal work is performed."

― William Walker Atkinson, The Science of Breathing
