Men who had apparently no voices at all, and who had pain in the throat while giving commands, suddenly found that it was a pleasure to use the voice. On the other hand, men whose health was run down so that they were on their way to forced retirement, were so changed in appearance that their civilian friends asked them what they were doing. Surgeon General Rupert Blue thought so highly of the health-building power of Mr. Lankow’s course of instruction that he made the following statement to Mr. Lankow in Washington: “Use my name for anything you like in connection with your system of teaching breath control.” Another health authority said: “Give the world two generations of children taught this trained, scientific method of breathing and you’ll make the community free of consumption.” Many of the world’s greatest singers have profited by Mr. Lankow’s instructions. Mary Garden, Director of the Chicago Opera Company and famous prima donna, has written “Half the world does not know that correct breathing means health, happiness and contentment. I had the joy of learning this truth from Mr. Lankow. Every day my voice became better--and my health too. His work is _really great_.” In this complete course of “Lessons” Mr. Lankow tells all the secrets of his wonderful work. Within a few days you, too, by following the simple directions Mr. Lankow advises, may be well on the road to such health, strength, mental clearness and physical beauty as you have never known before. For you will be working in harmony with Nature--and with Nature’s great and beneficent laws. The Publisher. _LESSON I_ Importance of Consciously Controlled Breathing Air is truly the breath of life. It is the vital fluid that animates our being; that stimulates into activity every one of the billion of cells that go to make up =the body=. It is a fact, conceded by every scientific man today, that the oxygen in the air we breathe is absolutely the greatest purifying force in all Nature. Yet there is but one way to get oxygen into your lungs and into your system--and this is to breathe it in. As long ago as two thousand years before the Christian Era, the Chinese and the Hindoos made elaborate studies in the art of breathing. Indeed, they developed a complex science having to do with control of the breath. Certain forms of breathing were employed for the cure of various diseases. Thus, for example, it was believed that controlled inhalations and exhalations would allay fevers; or, in a contrary condition of the body, induce a salutary rise in temperature.
