1.12
तस्य सञ्जनयन्हर्षं कुरुवृद्धः पितामहः | सिंहनादं विनद्योच्चैः शङ्खं दध्मौ प्रतापवान् ||१२||
tasya sañjanayan harṣhaṁ kuru-vṛddhaḥ pitāmahaḥ siṁha-nādaṁ vinadyochchaiḥ śhaṅkhaṁ dadhmau pratāpavān
Translation
Then the mighty Bhishma, the great grandsire of the Kuru dynasty, blew his conchshell very loudly, making a sound like the roar of a lion, giving Duryodhana joy.
Interpretation
Bhishma's conch roars like a lion — a sound of strength meant to inspire Duryodhana. Yet Bhishma himself knows the Pandavas' cause is righteous. He blows his conch out of duty to the king he has sworn to serve, not out of alignment with the Kaurava cause.
