This book is full of useful information, penetrating insights, and profound counsels for all spiritual aspirants. It is something more than an ordinary book. It is a personal contact with a great man, a teacher who has actually experienced what he teaches. An invaluable work indeed for all the seekers of the Supreme Truth.
The important thing is how much less you think of the body, of yourself as matter -- as dead, dull, insentient matter; how much more you think of yourself as shining immortal being. The more you think of yourself as spirit, the more eager you will be to be absolutely free from matter, body and senses. This is the intense desire to be free.
-Swami Vivekananda
