भीष्मवधोपाय-प्रश्नः (Inquiry into the means to overcome Bhīṣma) | Chapter 103
यथा देवासुरे युद्धे शक्रशम्बरयो: पुरा
yathā devāsure yuddhe śakraśambarayoḥ purā
Sañjaya said: “Just as in ancient times, in the war between the gods and the asuras, there was the famed battle between Śakra and Śambara…”
संजय उवाच
The verse frames the present conflict through a mythic precedent: epic warfare is interpreted via the recurring moral polarity of deva and asura—order versus disorder—suggesting that battles are judged not only by force but by alignment with dharma.
Sañjaya begins a simile, comparing the current battlefield events to an ancient devasura war, specifically invoking the well-known confrontation between Indra (Śakra) and the asura Śambara to heighten the scale and intensity of what he is describing.
