Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
कोपास्फालितदीर्घाग्रकरास्फोटेन पातयन् विचचार रणे देवान् दुष्प्रेक्ष्ये गजदानवः //
kopāsphālitadīrghāgrakarāsphoṭena pātayan vicacāra raṇe devān duṣprekṣye gajadānavaḥ //
Gaja, the elephant-demon, dreadful to behold, ranged over the battlefield; and in wrath, with the whip-like crack of his long, sharp-tipped hand, he struck the gods down.
This verse does not address Pralaya; it is a battlefield description emphasizing the destructive force and terrifying presence of the demon Gaja during a Deva–Dānava conflict.
Indirectly, it reinforces the Purāṇic ethic that unchecked kopa (anger) becomes a cause of harm and disorder—an implied warning for rulers and householders to govern passions and prevent violence from overwhelming dharma.
No Vāstu or ritual procedure is specified here; the verse is purely martial imagery, using the ‘whip-crack’ (āsphoṭa) of a hand as a poetic device to convey overwhelming force.
