9.8.11

स्वशरीराग्निना तावन्महेन्द्रहृतचेतस: । महद्‌व्य‌तिक्रमहता भस्मसादभवन् क्षणात् ॥ ११ ॥

sva-sariragnina tavan mahendra-hrta-cetasah mahad-vyatikrama-hata bhasmasad abhavan ksanat

sva-sarira-agnina
by the fire emanating from their own bodies
tavat
immediately
mahendra
by the tricks of Indra, the King of heaven
hrta-cetasah
their consciousness having been taken away
mahat
a great personality
vyatikrama-hatah
defeated by the fault of insulting
bhasmasat
turned to ashes
abhavan
became
ksanat
immediately.

By the influence of Indra, the King of heaven, the sons of Sagara had lost their intelligence and disrespected a great personality. Consequently, fire emanated from their own bodies, and they were immediately burned to ashes.
