This book is a documentation of selected notes and utterances of Swamiji about himself and his work. These are arranged chronologically so as to form what may be called a near autobiography of the saint.
Anything that is secret and mysterious in these systems of yoga should be at once rejected. The best guide in life is strength. In religion, as in all other matters, discard everything that weakens you, have nothing to do with it.
-Swami Vivekananda
