उत्पातवर्णनम् (Utpāta-varṇanam) — Catalogue of Portents
एको दीर्णो दारयति सेनां सुमहतीमपि । तां दीर्णामनुदीर्यन्ते योधा: शूरतरा अपि,यदि सेनाका एक सैनिक भी उत्साहहीन होकर पीछे हटे तो वह अपनी ही देखा-देखी अत्यन्त विशाल सेनाको भी भगा देता है (उसके भागनेमें कारण बन जाता है)। उस सेनाके पलायन करनेपर बड़े-बड़े शूरवीर सैनिक भी भागनेको विवश होते हैं
eko dīrṇo dārayati senāṃ sumahatīm api | tāṃ dīrṇām anudīryante yodhāḥ śūratārā api ||
Vyāsa said: Even a single soldier, once broken in spirit and giving way, can throw into disorder even a very great army. When that army is thus shattered, even warriors of greater valor are carried along and are forced to flee in its wake.
व्यास उवाच
Collective strength in war depends on morale and cohesion; one person’s collapse can trigger a chain reaction, so leaders must guard against panic and sustain steadiness (dhairya) and discipline.
In Bhīṣma Parva’s opening battle context, Vyāsa reflects on how an army can unravel: when one soldier breaks and retreats, the formation fractures, and even brave fighters may be swept into retreat as the rout spreads.
