kālanemī ruṣāviṣṭaḥ kṛtānta iva saṃkṣaye
kāṃścitkhaḍgena tīkṣṇena kāṃścin nārācavṛṣṭibhiḥ
kāṃścidgadābhirghorābhiḥ kāṃścidghoraiḥ paraśvadhaiḥ //

Under such circumstances, the demons taking their comrades to be the Devas began to slaughter one another. Kālanemi began to annihilate them like the angry Dharmarāja at the time of pralaya. He killed them with swords, arrows, clubs, battle-axes; severing the heads of some, the arms of others and crushed the chariots and the charioteers by the force of his chariot. He killed several with his fist. Thus Kālanemi killed his own armies. The demons on thus being fatally attacked by Kālanemi, and being horrified of the Devas began to yell and assume their proper forms. The angry Kālanemi could not recognise them when the demon Nemi said to him—"I am Nemi, recognise me. You have killed ten lacs of valiant demons through ignorance, whom the Devas even could not have killed. You should, therefore, discharge your Brahmāstra, without delay that defeats all the other weapons."—158-164.
