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.
If a piece of burning charcoal be placed on a man's head, see how he struggles to throw it off. Similar will be the struggle for freedom of those who really understand that they are slaves of nature.
-Swami Vivekananda
