The story of Bhaumāsura--how he kidnapped and made captive 16,000 princesses by collecting them from the palaces of various kings and how he was killed by Kṛṣṇa, the Supreme Lord of wonderful character--is all described by Śukadeva Gosvāmī to King Parīkṣit in the Śrīmad-Bhāgavatam. Generally, the demons are always against the demigods. This demon, Bhaumāsura, having become very powerful, took by force the umbrella from the throne of the demigod Varuṇa. He also took the earrings of Aditi, the mother of the demigods. He conquered a portion of heavenly Mount Meru and occupied the portion which was known as Maṇi-parvata. The king of the heavenly planets, Indra, therefore came to Dvārakā to complain about Bhaumāsura before Lord Kṛṣṇa.
