The Pandavas' conch sound—purposeful, aligned, confident—'shatters the hearts' (hṛdayāni vyadārayat) of the Kauravas. Why? This is psychological warfare. Duryodhana has already defeated himself internally (remember verses 1-10: 'our army is insufficient'). Now, hearing the Pandavas' coordinated sound, his internal defeat becomes external terror. The verse teaches: when you're already defeated internally, normal challenges feel overwhelming. Duryodhana's heart shatters not because the sound is terrifying, but because he's convinced himself he'll lose. The same sound that shatters a fearful heart inspires a confident one. What shatters you isn't the external challenge—it's your internal narrative meeting that challenge.
