Kṛṣṇa and Balarāma mounted a chariot and went to Prabhāsa, where They approached the shore and were worshiped by the presiding deity of the ocean. Kṛṣṇa asked the ocean to return His spiritual master’s son, and the lord of the ocean replied that a demon dwelling within the ocean named Pāñcajana had taken the boy away. Hearing this, Śrī Kṛṣṇa entered the ocean, killed that demon and took the shell that had grown from his body. But when Kṛṣṇa did not find His guru’s son within the demon’s belly, He went to the planet of Yamarāja, the lord of death. Yamarāja came forward when he heard Kṛṣṇa blow the Pāñcajanya conchshell and devotedly worshiped Him. Lord Kṛṣṇa then asked Yamarāja for Sāndīpani Muni’s son, and Yamarāja immediately gave him to the two Lords.
