|Chapter 1: Observing the Armies on the Battlefield of Kurukshetra|
tasya sanjanayan harsham
sankham dadhmau pratapavan
Then Bhisma, the great valiant grandsire of the Kuru dynasty, the grandfather of the fighters, blew his conchshell very loudly like the sound of a lion, giving Duryodhana joy.
Bhishma, who is one of the 12 mahajans (great personalities), knew very well that both religion and the personification of religion (Krishna) is on the side of the Pandavas. So the defeat of the Kauravas was imminent. He has pursued many diplomatic and peace missions in the past to avoid this war. But now he indicates that the time for talking is over. It is now time for war. Srila Prabhupada explains, "The grandsire of the Kuru dynasty could understand the inner meaning of the heart of his grandson Duryodhana, and out of his natural compassion for him he tried to cheer him by blowing his conchshell very loudly, befitting his position as a lion. Indirectly, by the symbolism of the conchshell, he informed his depressed grandson Duryodhana that he had no chance of victory in the battle, because the Supreme Lord Krsna was on the other side. But still, it was his duty to conduct the fight, and no pains would be spared in that connection."
