SB 10.43.30
ayam casyagrajah sriman
ramah kamala-locanah
pralambo nihato yena
vatsako ye bakadayah
Translation:
This lotus-eyed elder brother of His, Lord Balarama, is the proprietor of all transcendental opulences. He has killed Pralamba, Vatsaka, Baka and other demons.
Purport:
In fact two of the demons mentioned here were killed by Krsna, not Balarama. The reason for the mistake is that as news of Krsna’s exploits spread among ordinary people, the facts became somewhat muddled. The same tendency can be observed in modern newspapers.
