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.
Those who work at a thing heart and soul not only achieve success in it but through their absorption in that they also realize the supreme truth -- Brahman. Those who work at a thing with their whole heart receive help from God.
-Swami Vivekananda
