The Bhagavad Gita. Relating a conversation between Lord Krishna and a follower, Prince Arjuna, prior to a fierce battle between Arjuna's forces and those of his kinsmen, the Bhagavad Gita details much of the philosophy of the Hindu religion. It is a beautiful book of some 700 verses that, like scripture of any religion, teaches Man how to live among men in peace and love. You don't need to be a Hindu to be overwhelmed by the beauty of the wisdom within.
