Paramahaṁsa: ...Madhusūdana because He killed the demon Madhu. But who was that Madhu?
Prabhupāda: A demon, it is said.
Paramahaṁsa: But I don't think we've heard that story before.
Prabhupāda: In the beginning, when Brahmā was created, one demon, Madhu, came to swallow him. And Kṛṣṇa killed him. Madhu-Kaitava, two brothers, Madhu and Kaitava.
Paramahaṁsa: He came to swallow Brahmā?
Prabhupāda: Yes.
Paramahaṁsa: So he was one of the first demons killed.
Prabhupāda: Yes.
