Educational Q&A

The verse stresses the warrior-ethic of making one’s spoken commitment real through action: truth (satya) is not only a moral claim but a vow that must be upheld, even amid the harsh demands of battle.

Karna urges the addressed Bhārata warrior to attack and kill the assembled Pāṇḍavas and the Somaka archers, framing the act as the means to ‘make true’ a prior statement or promise.
