The Roots of the Bhagavadgita Volume II

The Svabhavikasutra is the original text on which the Bhagavadgita has been interpolated. The additions include reference to caste and the system of four classes, with a religious devotion to the god Krishna, and a war as background. The roots of the Bhagavadgita, the Svabhavikasutra, focuses on a deep spiritual philosophy, without a reference to a caste system, or to Arjuna or Krishna, or to a war.
