You are that very same Supreme Person, my Lord, and You have now appeared in the home of Vasudeva with Your plenary portion.

The term suretarāṁśa-rājñām indicates that the demoniac kings slain by Kṛṣṇa were in fact expansions or incarnations of the enemies of the demigods. This fact is elaborately explained in the Mahābhārata, which reveals the specific identities of the demoniac kings.
