पज्च नद्यो वहन्त्येता यत्र नि:सृत्य पर्वतात्
pañca nadyo vahanty etā yatra niḥsṛtya parvatāt
Karna said: “Five rivers flow here, issuing forth from the mountain.”
कर्ण उवाच
Attentive observation of reality—such as terrain and natural resources—is a form of practical wisdom that influences responsible action; in war, clear seeing precedes choices that carry moral weight.
Karna is describing a landscape feature: five rivers that originate from a mountain, likely as part of situational assessment relevant to movement and tactics in the ongoing conflict.
