The main object of this book is to discuss the science of Yoga in as simple and rational a manner as possible, and also to debunk some of the nonsense that continues to be said and believed on the subject. A must for all those are eager to clarify their conception about Yoga.
Nature grinds all of us. Keep count of the ounce of pleasure you get. In the long run, nature did her work through you, and when you die your body will make other plants grow. Yet we think all the time that we are getting pleasure ourselves. Thus the wheel goes round.
-Swami Vivekananda
