Matsya Purana — War of Devas and Dānavas: Yama and Kubera Defeated; Kālanemi’s Māyā and the A...
जघ्ने मर्मसु तीक्ष्णाग्रैर् असुरं भीमदर्शनम् ताभ्यां बाणप्रहारैः स किंचिदायस्तचेतनः //
jaghne marmasu tīkṣṇāgrair asuraṃ bhīmadarśanam tābhyāṃ bāṇaprahāraiḥ sa kiṃcidāyastacetanaḥ //
He struck the dreadful-looking asura at his vital points with sharp-pointed arrows; and by the impact of those two arrow-blows, the demon was for a moment weakened, his senses dulled.
This verse does not discuss pralaya or cosmology; it focuses on a battle scene, emphasizing tactical strikes at vital points (marmas) and the resulting loss of strength and clarity in the asura.
Indirectly, it reflects the Purāṇic ideal of confronting adharma with disciplined force—precise, purposeful action rather than uncontrolled violence—an ethic applicable to kingship (protecting order) and to householders (self-control in conflict).
No vastu, temple-building, or ritual procedure is stated here; the only technical term is "marma" (vital points), relevant to martial/medical notions rather than architecture.
