Matsya Purana — The Advent of Narasiṃha and Hiraṇyakaśipu’s Weapon-Assault
ते दानवाः पाशगृहीतहस्ता महेन्द्रतुल्याशनिवज्रवेगाः समन्ततो ऽभ्युद्यतबाहुकायाः स्थितास्त्रिशीर्षा इव नागपाशाः //
te dānavāḥ pāśagṛhītahastā mahendratulyāśanivajravegāḥ samantato 'bhyudyatabāhukāyāḥ sthitāstriśīrṣā iva nāgapāśāḥ //
Those Dānavas, with nooses gripped in their hands, swift as Indra’s thunderbolt and lightning, stood all around with their arms raised—like serpent-nooses, as though triple-headed, poised to strike.
Nothing directly about Pralaya is stated here; the verse is a battlefield description emphasizing the Dānavas’ readiness and weaponry (pāśa/noose) through vivid similes.
Indirectly, it underscores vigilance and preparedness in the face of aggression—qualities the Matsya Purana often associates with righteous protection (rakṣaṇa) and the maintenance of order, though this particular verse is not a direct dharma injunction.
No Vāstu or ritual procedure is specified; the technical focus is martial—pāśa (noose-weapon) and the nāga-pāśa simile used to convey encirclement and imminent capture.
