Bhagavad Gita: Chapter 1, Verse 15
पाञ्चजन्यं हृषीकेशो देवदत्तं धनञ्जय: |
पौण्ड्रं दध्मौ महाशङ्खं भीमकर्मा वृकोदर: || 15||
pāñchajanyaṁ hṛiṣhīkeśho devadattaṁ dhanañjayaḥ
pauṇḍraṁ dadhmau mahā-śhaṅkhaṁ bhīma-karmā vṛikodaraḥ
pauṇḍraṁ dadhmau mahā-śhaṅkhaṁ bhīma-karmā vṛikodaraḥ
Hrishikesh blew his conch shell, called Panchajanya, and Arjun blew the Devadutta. Bheem, the voracious eater and performer of herculean tasks, blew his mighty conch, called Paundra.
