The Bhagvad Gita, a treatise of Aryan Philosophy, is translated into almost all the spoken languages of the civilized world and is read today with reverence and admiration all over the world. Every Indian founder of religion has recognized it as an authority and taken it as the basis of the School of thought he founded. The Bhagvad Gita is the quint-essence of Philosophy and Religion, of ethics and morality, social and religious, temporal and spiritual. It is a guide as much to the man of world as to the ascetic who has renounced the world. This unique exposition of the philosophy of the Bhagvad Gita is meant for both the sceptic and the believer. The commentary, as far as possible, attempts at providing reasoned arguments supporting the philosophy substituting the traditional preference to support by mere text from scriptures which while it may serve as authority to some may not be so to others in this Age of Reasoning.
