Rudra Vaishnava Sampradaya - Commentary

Bhishmadeva hearing such words of high esteem, roared like  a  lion  and  to
gladden the heart of Duryodhana blew  a  thunderous  blast  from  his  conch
shell.


Brahma Vaishnava Sampradaya - Commentary

Madhvacarya has no commentary so we present Baladeva Vidyabhusanas.

Bhishma become elated hearing the praises given him by Duryodhana.  Thus  to
eliminate the fear he knew Duryodhana was concealing in his heart he  roared
like a lion,  simha-nadam  means  roaring  like  a  lion  and  then  blew  a
thunderous blast on his conchshell. By only sounding a blast  on  his  conch
shell without speaking Bhishma signified that true to  ksatriya  or  warrior
code of warfare he would fight until death.


Shri Vaishnava Sampradaya - Commentary
There is no commentary for this verse.


Kumara Vaishnava Sampradaya - Commentary
So Duryodhana full of internal anxiety deceptively addressed  the  preceptor
Dronacarya attempting to conceal his fear at the might of the Pandava  army.
Drona understanding the offensive innuendo by the words  inner  significance
ignored Duryodhana  being  dissatisfied  by  the  subtle  sarcasm  concealed
within the words. At this time  the  valiant  grandsire  Bhishma  perceiving
Duryodhanas inner despondency, roared like a lion  and  blew  a  thunderous
blast on his conch shell just to
increase Duryodhanas joy.
