Sanjay was the divine charioteer and narrator who described the Kurukshetra war to the blind King Dhritarashtra. Blessed with divine vision (divya drishti) by Ved Vyasa, he could see events occurring on the battlefield from afar and narrated them in real-time. This narration forms the basis of the Bhagavad Gita within the Mahabharata. Balaram was Krishna's brother, Ved Vyasa was the author, and Vidur was the wise half-brother of Dhritarashtra.
