SB 6.12.5
vrtrasya karmati-mahadbhutam tat
surasuras carana-siddha-sanghah
apujayams tat puruhuta-sankatam
niriksya ha heti vicukrusur bhrsam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The denizens of various planets, like the demigods, demons, Caranas and Siddhas, praised Vrtrasura’s deed, but when they observed that Indra was in great danger, they lamented, “Alas! Alas!”
