Vyasa’s Jaya, the core of the Mahabharata, is structured in the form of a dialogue between Dhritarashtra and Sanjaya, his adviser and charioteer. Sanjaya narrates the particulars of the Kurukshetra War, fought in eighteen days, chronologically. Dhritarashtra at times asks questions and expresses doubts, sometimes lamenting, knowing of the destruction caused by the war to his sons, friends and kinsmen. Sanjaya, in the beginning, gives a description of the various continents of the Earth and numerous planets, and focuses on the Indian subcontinent. Large and elaborate lists are given, describing hundreds of kingdoms, tribes, provinces, cities, towns, villages, rivers, mountains, forests, etc. of the (ancient) Indian subcontinent. Additionally, he gives descriptions of the military formations adopted by each side on each day, the death of individual heroes and the details of the war-races. Eighteen chapters of Vyasa’s Jaya constitute the Bhagavad Gita, a sacred text in Hinduism. Thus, the Jaya deals with diverse subjects, such as geography, history, warfare, religion and morality.
