Quotes

 * In the Hindu scriptures history is represented as a ceaseless conflict between the Dharma and Adharma — between the moral, idealistic, spiritual forces and the unregenerate forces of darkness, lust, and evil — in which the Dharma always wins. History, ethics, politics, and social speculation are blended together in a cosmic ritual scheme, with gods and culture-heroes acting as conciliatory mediators between the sacred world and the profane world. The battle between good and evil is conceived as a cosmic sacrifice for the common good, ultimately uniting gods and men in the rule of Raja-dharma.
