Yoga is an ancient health-art developed and perfected over the centuries by the Sages and Wise Men of ancient India. Yoga is not a religion, a metaphysical doctrine, or a philoso­phy. It is not magic or mysticism, although the amazing im­provements it can make in your health, your appearance and your youthfulness may often seem magical, even miraculous. For thousands of years the Yogis of India have used the simple, reasonable principles of Yoga to regain the zest and enthusiasm and good health of their youth, to preserve into middle age the clear-thinking and sound physique of man­hood, and to continue enjoying even in old age the resilience, healthfulness, and well-being of their younger years.

Yoga can take years off your face and years from your body—and add years to your life. There are certain secret methods by which the Yogis keep the flexibility and "spring" of early youth in their joints and muscles and limbs well into the declining years. It is a common sight to see, in the crowded, colorful streets of Bombay or New Delhi, Yogis well into their seventies and even their eighties, with the straight, grace­ful posture of a boy, walking with the elastic, springy step of youth... with firm, healthy bodies, their hair dark and glossy and un-streaked with grey. Firm, unlined faces … clear, undimmed eyes.

Not only does Yoga make you look and feel years younger, years healthier, but it lends your body superb healthiness. This system of Yoga does not demand difficult positions and pos­tures, uncomfortable exercises or strenuous diets. This is where it differs from every other book on Yoga previously published. It describes the simple, easy, "common-sense" secrets of using the natural health God gave you. It works likemagic because it enables the body to realize its full potential of good health.

You know that Nature built into your body certain nat­ural safeguards against disease, certain "defense mechanisms" for self-repair. Well, modern Yoga helps the body's machin­ery function smoothly, efficiently, at peak performance. It encourages your body to derive every last possible atom of nutritive value from the food you now eat (so different from the natural diet of your ancestors) ... to get every second of refreshment and rest from your sleep ... to attain regularity, relief from little aches and pains, the ability to sleep deep and wake refreshed that can make the difference from feeling "pretty good" to feeling "terrific!"

Yoga assists all your muscles and bones and organs to oper­ate at top masculine or female vigor. Yoga stimulates into peak performance the latent abilities of your body to throw off the attacks of disease, the psychosomatic "nervous illnesses" that nag and plague millions. Do you suffer from insomnia, "nerves"? Are you without appetite? Do you find it hard to relax? Do you smoke too much, feel "worn out" by after­noon, find as you grow older that you cannot enjoy full life and day to day vitality? Yoga has the amazing power to refresh and relax you, soothe your nerves, calm your mind, give you the serenity and strength and inner stamina that is part of the "Magic of the East."

Yoga prevents the premature grey in your hair, the ugly wrinkles in your face. It tightens those sagging muscles that give you that "tired look." It puts new zest in your appetite, brings back the sparkle in your eyes—gives that wonderful sensation of feeling "fit as a fiddle."

For far too long the secret wisdom and lore of this ancient art has been denied to men and women of the Western world. I have devoted years of study and experiment to the cause of revising and simplifying the ancient practices of Yoga and to making them accessible to modern Americans. I have adapted, modified and "streamlined" Yoga so that it will be of the very highest possible value to you today. In so doing, I have taken full cognizance of modern advances in nutrition, vitamin-therapy, health foods, and the new systems of diet and exer­cise, as well as the most recent medical knowledge and research into methods of revitalizing the human body and halting the "aging process."

You want a full life. You want to feel well. You want en­ergy, vitality, staying power. All these can be yours. This sys­tem of Yoga applies age-old secrets to everyday life at the modern tempo. It tells how only a few minutes easy, practical application can restore your lost youth ... put new zest into your undertakings ... and enable you to enjoy to the full a sense of health, energy and creative living which will make all the difference to your future happiness.
