पाञ्चजन्यं हृषीकेशो देवदत्तं धनञ्जय: |
पौण्ड्रं दध्मौ महाशङ्खं भीमकर्मा वृकोदर: ||15||
Hrishikesh blew his conch shell named Panchajanya, and Dhananjaya blew his conch Devadutta. and Bhima, the voracious eater, and the performer of Herculean tasks blew his mighty conch named Paundra.
Blowing conches was sort of like a tradition or a step to indicate the beginning of the war. Loud Sounds were instrumental in installing the fears in the heart of the enemy. Different sounds can stimulate a variety of reactions in us. Hence, conches were blown like a roaring of a lion that instills fear in the opponent.
Hrishikesh (one of the thousand names of Shri Krishna which means the Lord who directs the senses of the devotees) blew his conch shell named Panchajanya.
Dhananjaya (one of the many names of Arjun which means the one who conquers wealth and brings prosperity and wealth in the land he goes to) blew his conch shell named Devadutta.
Bhima who is mentioned in this shloka along with his qualities: the performer of Herculean tasks and the voracious eater, blew his mighty conch Paundra.
The Sound of these conches motivated and encourages the soldiers on the Pandava side to fight with all their might. The specific name of Shri Krishna is mentioned in this shloka: Hrishikesh. It means that by residing in the hearts of all living entities, Shri Krishna directs their senses. Arjuna was charioted by Krishna himself in this mighty battle not only in physical capacity but also spiritually & mentally guiding his senses in the entire battle.
