स घोषो धार्तराष्ट्राणां हृदयानि व्यदारयत्।
नभश्च पृथिवीं चैव तुमुलो व्यनुनादयन्।।1.19।।
।।1.19।।पाण्डवसेनाके शंखोंके उस भयंकर शब्दने आकाश और पृथ्वीको भी गुँजाते हुए अन्यायपूर्वक राज्य हड़पनेवाले दुर्योधन आदिके हृदय विदीर्ण कर दिये।
The uproarious sound of the Pandavas conch shells being blown caused great fear to the sons of Dhritarastra. This is what this verse means. How? By its power, by its power it made the heavens and the earth resound, filling them all with its reverberations.
Madhvacarya has no commentary so we present Baladeva Vidyabhusanas. The thunderous sound of Pancajanya the divine conch shell of Lord Krishna and the Pandavas divine conch shells along with their army was devastating and heart shattering in the sense that Bhishma and all those in favour of the Kauravas felt pain in their heart as if their heart was actually shattered. The Kaurava army had also made an uproarious noise just minutes before but it did not have the power to create any anxiety in the army of the Pandvas and this was undeniably proven by the potency of the Pandavas response.
Duryodhana while witnessing the strength of the Pandavas army supported by the might of Bhima weighed his own armies strength under the command of Bhishma and perceiving the mood of his perceptor Dronacarya, he could understand the inadequacy in his own troops and the perfection of strength on the Pandavas side to be victorious and internally this aggrieved him heavily. Bhishma seeing all this gave a roar like a lion and blew a mighty, reverberating blast on his conchshell which was followed by a tumultous beating of drums, blaring of horns and blasting of conchshells as if indicative of the victory in order to cheer up Duryodhana. Immeadiately upon hearing this Lord Krishna and Arjuna seated in their majestic chariot capable of conquering all the worlds; both seized their conchshells and reverberated a sound that shook all the worlds. Thereafter Bhima, Yudhisthira, Nakula and Sahadeva and the rest of the maha-rathas of the Pandava army blew their conchshells and the roar which was heard cleaved the hearts of Duryodhana and the army of the Kauravas and in their hearts they felt that the battle was already lost. Thus did Sanjaya narrate to Dhritarashtra whose only concern was for the success of his son Duryodhana and the Kauravas in the battle.
