This famous and marvellous Sanskrit poem occurs as an episode of the Mahabharata, in the sixth-or “Bhishma”-Parva of the great Hindu epic. It enjoys immense popularity and authority in India, where it is reckoned as one of the “Five Jewels,” -pancharatnani- of Devanagiri literature. In plain but noble language it unfolds a philosophical system which remains to this day the prevailing Brahmanic belief, blending as it does the doctrines of Kapila, Patanjali, and the Vedas.
My personal belief is that you can learn more about others by understanding what they believe. You can then carry on a much greater conversation with them based upon the texts they hold dear.
