Lord Krishna as a peace emissary of Pandavas traveled to Hastinapura persuading Kauravas to avoid bloodshed of their own kin. However, Duryodhana conspired to arrest him that resulted in failure of mission. After Krishna’s peace mission failed and the war seemed inevitable, Vyasa approached Dhritarashtra and offered to grant him divine vision, so that Dhritarashtra could see the war. However, not willing to see his kin slaughtered, Dhritarashtra asked that the boon be given to Sanjaya his charioteer. Sanjaya dutifully narrates the war to his liege, reporting how Bhima killed all his children. Sanjaya would console the blind king while challenging the king with his own viewpoints and morals. When Lord Krishna displayed his Vishvarupa (Universal Form) to Arjuna on the battlefield of Kurukshetra, Dhritarashtra regretted not possessing the divine sight.
