सम्पतन्तमभिप्रेक्ष्य महात्मानं पितामहम्
sampatantam abhiprekṣya mahātmānaṃ pitāmaham
Sañjaya said: Seeing the great-souled Grandsire Bhīṣma rushing down into the fray, they fixed their gaze upon him—venerable authority descending into the violence of war, where even the most revered must act according to the duty (dharma) they have chosen.
संजय उवाच
The line highlights the ethical tension of dharma in war: even a revered elder like Bhīṣma, embodying authority and virtue, enters the battlefield due to his vowed duty and chosen allegiance—showing how personal vows and social roles can compel action amid moral complexity.
Sañjaya describes the moment when Bhīṣma, addressed as the Grandsire, is seen moving swiftly into action; the onlookers (implied by the participial construction) watch him intently as he advances in the battle scene.
