Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
रणागारमिवोद्गारं तत्याजासुरनन्दनः तदस्त्रतेजसा तस्य रूपं दैत्यस्य नाशितम् //
raṇāgāramivodgāraṃ tatyājāsuranandanaḥ tadastratejasā tasya rūpaṃ daityasya nāśitam //
The son of the Asuras let out a roar like the tumult of a battlefield; yet by the blazing power of that weapon, the Daitya’s very form was destroyed.
It does not describe cosmic Pralaya directly; it uses the idea of “form being destroyed” to depict the annihilating force of an astra in a battle episode.
Indirectly, it reinforces the Purāṇic ethic that unrighteous force (Daitya aggression) is checked by rightful power; kings are expected to restrain violence through dharmic strength and disciplined use of weapons.
No Vāstu or temple-ritual rule is stated here; the key technical term is astra-tejas—ritually empowered, divinely charged weapon-power—often tied to mantra and consecration in broader Purāṇic tradition.
