कर्ण उवाच
The verse emphasizes situational awareness: a leader in war must accurately note terrain features—rivers and vegetation—since they shape movement, tactics, and the safety of troops.
Karna is describing a particular region relevant to the ongoing battle context, identifying key natural landmarks—five rivers and pīlu-tree groves—likely to orient others and inform tactical decisions.
