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.
The Kingdom of Heaven is within us. God is within us. He is the Soul of our souls. See Him in your own soul. That is practical religion. That is freedom.
-Swami Vivekananda
