His glorious grandsire (Bhishma), the oldest of the Kauravas, in order to cheer Duryodhana, now roared like a lion, and blew his conch.

Then, to raise his spirits, the mighty Bhishma, eldest of the Kurus and grandsire of the family, roared like a lion and blew his conch.

Bhishma responds not with words but with action. Seeing Duryodhana's unease, the old warrior gives a lion's roar and blows his conch, the traditional signal that battle is about to begin. He is called the elder of the Kurus and the grandsire, which marks his authority over both families. His aim is to cheer Duryodhana, and the verse shows his loyalty to the throne he has served all his life, even in a cause he had warned against. The sound of his conch sets the armies in motion.
