Rudra Vaishnava Sampradaya - Commentary

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.


Brahma Vaishnava Sampradaya - Commentary

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.


Shri Vaishnava Sampradaya - Commentary

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.
