Shrimad Bhagwat Geeta Chapter 1 shlok 16, 18

Yudhisthira, the eldest of the Pandavas, is referred to as “King” in this context. His demeanor consistently reflected regal grace and nobility, whether residing in a grand palace or enduring exile in the forest. He earned the title of “King” through the performance of the Rājasūya Yajña, a royal sacrifice that garnered tributes from rulers all across the world.

In this verse, Sanjay also addresses Dhritarashtra as the “Ruler of the earth.” This appellation serves as a reminder of his responsibilities as the leader of the nation. With numerous kings and princes on both sides of this war, it seems as if the entire world has split into two factions. The enormity of this war portends irrevocable destruction. The only individual who could potentially halt the war at this critical juncture is Dhritarashtra, and Sanjay is keen to ascertain his willingness to do so.
