In the Mahabharata, Sanjaya, blessed with divine vision, described the Kurukshetra war scene by scene to the blind king:

In the Mahabharata, Sanjaya narrated the events of the Kurukshetra war to the blind king Dhritarashtra, the father of the Kauravas.

About Sanjaya:

• He was the charioteer and adviser of King Dhritarashtra.
• He was the son of Gavalgana, and belonged to the "suta" community of charioteers and bards.
• The sage Vyasa granted him "divya drishti" (divine vision), so that he could see everything happening on the distant battlefield and describe it to the king.
• The Bhagavad Gita opens with Dhritarashtra asking Sanjaya what his sons and the sons of Pandu did when they gathered at Kurukshetra.
• The whole Bhagavad Gita is presented as Sanjaya's report of the dialogue between Krishna and Arjuna.
• Sanjaya often advised Dhritarashtra to make peace with the Pandavas.

About Dhritarashtra:

• He was born blind, so the throne was initially given to his younger brother Pandu.

• His wife was Gandhari, who blindfolded herself for life to share her husband's blindness.
• They had 100 sons, the Kauravas, led by Duryodhana, and one daughter, Dushala.
• His love for his son Duryodhana led him to ignore injustice towards the Pandavas.
• After the war, he retired to the forest with Gandhari and Kunti, where they died in a forest fire.
