Dear Prabhujis and Matajis
Please accept my humble obeisances. All glories to Srila Prabhupada and Gurudev.
In Bhagavad Gita verse 1.19 Lord Krishna says,
sa ghosho dhaartarashtraanaam / hrdayaani vyadaarayat
nabhash ca prthvim caiva / tumulo bhyanunaadayan
When Bhishma and the others on the side of Duryodhana blew their respective conchshells,there was no heart-breaking on the part of the Pandavas. Such occurences are not mentioned,but in this particular verse. It is mentioned that the hearts of the sons of Dharashtra were shattered by the sounds vibrated by the Pandavas' party.This is due to the Pandavas and their confidence in Lord Krishna .One who takes shelter of the Supreme Lord has nothing to fear,even in the midst of greatest calamity.
Your humble servant,
