Sankara's 'thousand teachings' on the distinction between the senses, mind, body, intellect, and the true Self. In translating as well as in drawing up the notes, the author has closely followed the authoritative commentary of Ramatirtha.
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
