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.
Work unto death -- I am with you, and when I am gone, my spirit will work with you. This life comes and goes -- wealth, fame, enjoyments are only of a few days. It is better, far better, to die on the field of duty, preaching the truth, than to die like a worldly worm. Advance!
-Swami Vivekananda
