द्रोणपर्व — अध्याय १६२: प्रातःसंध्यायां युद्धप्रवृत्तिः तथा रजोमेघे संमूढता
शरौघै: पूरयन्तौ तावाकाशं च दिशस्तथा । अलक्ष्यौ समयुध्येतां महत् कृत्वा शरैस्तम:,वे दोनों अपने बाणसमूहोंसे आकाश और दिशाओंको भरते हुए उनके द्वारा महान् अन्धकारकी सृष्टि करके अलक्ष्य होकर युद्ध करते रहे
saraughai pūrayantau tāv ākāśaṃ ca diśas tathā | alakṣyau samayudhyetāṃ mahat kṛtvā śarais tamaḥ ||
Sañjaya said: The two warriors, flooding the sky and all directions with volleys of arrows, created a vast darkness with their shafts; hidden from sight, they continued to fight on.
संजय उवाच
The verse highlights how unchecked martial intensity can metaphorically and literally produce 'darkness'—a loss of visibility and discernment—suggesting that even in war, dharma requires clarity, proportion, and restraint so that power does not eclipse right judgment.
Sañjaya describes two combatants exchanging such dense volleys of arrows that the sky and directions seem filled; the arrow-storm creates a darkness, making the fighters hard to see as they continue battling.
