BG 1.19: The terrific sound thundered across the sky and the earth, and shattered the hearts of your sons, O Dhritarasthra.
Sanjay conveyed to Dhritarashtra, that the tremendous sound of the various conch shells from the Pandava army was shattering the hearts of his sons. Whereas, he did not mention any such reaction from the Pandavas, when the Kauravas were creating a commotion. The Kauravas were fearful, as their conscience pricked them for their crimes and misdeeds. They were relying solely on their physical strength to fight the war. However, the Pandavas were confident and felt protected, as the Supreme Lord Shree Krishna was by their side, their victory was definite.
