The Hindu-Yogi Science of Breath

"Yogi system of Complete Breathing is of vital importance to every man, woman and child who wishes to acquire health and keep it. Its very simplicity keeps thousands from seriously considering it, while they spend fortunes in seeking health through complicated and expensive "systems." Health knocks at their door and they answer not. Verily the stone which the builders reject is the real cornerstone of the Temple of Health."
