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.
Look here -- we shall die! Bear this in mind always, and then the spirit within will wake up. Then meanness will vanish from you, practicality in work will come, you will get new vigor in mind and body, and those who come in contact with you will also feel that they have really got something uplifting from you.
-Swami Vivekananda
