After Lord Kṛṣṇa had thoroughly defeated the ghosts and hobgoblins fighting under Lord Śiva, the Śiva-jvara weapon — a personification of fever with three heads and three legs — approached Lord Kṛṣṇa to fight Him. Seeing the Śiva-jvara, Kṛṣṇa released His Viṣṇu-jvara. The Śiva-jvara was overwhelmed by the Viṣṇu-jvara; having nowhere else to turn for shelter, the Śiva-jvara began to address Lord Kṛṣṇa, glorifying Him and asking for mercy. Lord Kṛṣṇa was pleased with the Śiva-jvara, and after the Lord had promised him freedom from fear, the Śiva-jvara bowed down to Him and departed.
