Srimad Bhagavadgita Sadhaka Sanjivani -Swami Ramsukhdas
After the expiry of twelve years of exile and residing in an unknown place for one year, the Pandavas demanded half of their kingdom from Duryodhana, as was his promise but he refused to give even as much land as could be covered by the point of a needle, without waging war. The Pandavas sought permission from their mother Kunti, and accepted the challenge of a war. After this decision, both the Kauravas and the Pandavas, began preparation for it.
Sage Veda Vyasa had great affection for Dhrtarastra, the blind king of Hastinapura. Due to his affection, he said to Dhrtarastra, "War and massacre of the Ksatriyas is inevitable. If you want to see the scene of the battlefield, I can endow you with divine sight so as to enable you to see scene of war, from the place you are sitting." Dhrtarastra said, "I have been blind all my life. Now I don't want to see the slaughter of my own kith and kin. But I want to hear the details of the war." Then sage Vyasa said," I endow Sanjaya with this divine sight by which he will know, hear and see, not only the incidents of the battlefield but also the ideas, in the minds of the warriors and will narrate these to you." Saying so, sage Vyasa endowed Sanjaya with divine vision.
The battle started on the battlefield of Kuruksetra at the appointed hour. Sanjaya stayed in the battlefield, for ten days. When Bhisma being badly wounded with arrows, fell off the chariot, Sanjaya conveyed the message to Dhrtarastra who at that time was in Hastinapura. Hearing this news, Dhrtarastra was filled with great sorrow and started to cry. Then he asked Sanjaya to narrate to him all the details of the war. Upto the twenty-fourth chapter of the Bhisma-Parva (section), Sanjaya narrated the incidents of the war. At the beginning of the twenty-fifth chapter, Dhrtarastra asks Sanjaya
- In the MahabharaTa there are eighteen sections. In those sections there are several sub-sections. In the Bhisma section there is this Bhagavadgita, a sub-section which begins with the thirteenth chapter of the Bhisma section and ends with the forty-second chapter.
