SB 10.15.39
tayos tat su-mahat karma
nisamya vibudhadayah
mumucuh puspa-varsani
cakrur vadyani tustuvuh
Translation:
Hearing of this magnificent feat of the two brothers, the demigods and other elevated living beings rained down flowers and offered music and prayers in glorification.
Purport:
Srila Sanatana Gosvami comments that the demigods, great sages and other exalted beings were all astonished and ecstatic upon seeing the unusually swift and nonchalant way in which Krsna and Balarama killed the very powerful ass demons in the Tala forest.
