Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
तस्मिन्प्रतिहते चास्त्रे पावकास्त्रं व्यजृम्भत जज्वाल कायं जम्भस्य सरथं च ससारथिम् //
tasminpratihate cāstre pāvakāstraṃ vyajṛmbhata jajvāla kāyaṃ jambhasya sarathaṃ ca sasārathim //
When that weapon had been checked, the Fire-weapon, the Pāvakāstra, flared forth; it set Jambha’s body ablaze—together with his chariot and his charioteer.
This verse does not discuss Pralaya; it depicts a combat sequence where a repelled weapon is followed by the deployment of the Fire-weapon (Pāvakāstra), emphasizing the Purāṇic theme of escalating astras rather than cosmic dissolution.
Indirectly, it reflects the kṣātra (royal/warrior) ethic found across the Matsya Purāṇa: when one means is neutralized, a protector must respond decisively with an appropriate countermeasure—here portrayed through the disciplined use of astras in battle.
No Vāstu or temple-architecture rule is stated in this verse; its ritual subtext is the concept of mantra-empowered astras (divine missiles) associated with deities like Agni, illustrating how sacred power is invoked for specific effects.
