The ocean deity replied, "The boy was not actually taken by me but was captured by a demon named Pañcajana. This great demon generally remains deep in the water in the shape of a conchshell. The son of Your teacher might be within the belly of the demon, having been devoured by him."
On hearing this, Kṛṣṇa dove deep into the water and caught hold of the demon Pañcajana. He killed him on the spot but could not find the son of His teacher within his belly. Therefore He took the demon's dead body (in the shape of a conchshell) and returned to His chariot on the beach of Prabhāsa-kṣetra. From there He started for Saṁyamanī, the residence of Yamarāja, the superintendent of death. Accompanied by His elder brother, Balarāma, who is also known as Halāyudha, Kṛṣṇa arrived there and blew on His conchshell.
