Nowhere in the world do we get such a complete study of the human personality in all its exhaustive features as in the Taittiriya Upanisad. Apart from a clear description of the five sheaths, it gives a vivid picture of the exhaustive training imparted in the educational system of the period, with instructions and advice on, how to live Vedanta in life; Taittiriya Upanisad occupies an unrivalled place in the Divine Tradition of Hinduism. The Upanisad, declares a manifesto upon the 'Hindu way of Living'. These Commandments have a democratic Hindu touch which is the unique speciality of Hindu philosophy. "He who realises Brahman attains the Supreme Brahman - Truth, Knowledge and Infinite." In his commentary of this Upanishad, the journalist, the logician, the scholar and the master of English Literature - Swami Chinmayananda - is at His best.
