Matsya Purana — The Battle for Tripura: Portents
आक्रोशे ऽपि समप्रख्ये तेषां देहनिकृन्तनम् प्रवृत्तं युद्धमतुलं प्रहारकृतनिःस्वनम् //
ākrośe 'pi samaprakhye teṣāṃ dehanikṛntanam pravṛttaṃ yuddhamatulaṃ prahārakṛtaniḥsvanam //
Even amid their cries—each matching the other in fury—there began among them an unequalled battle: bodies hewn down, resounding with the din born of blows.
This verse does not discuss Pralaya; it is a vivid battlefield depiction focused on human conflict, cries, and the din of weapon-strikes.
It aligns more with kṣatriya-context narration: war is portrayed as intense and bodily destructive, implicitly underscoring the grave responsibility of rulers to weigh conflict carefully and uphold dharma even amid battle.
No Vāstu, temple-building, or ritual procedure is stated here; the verse is purely martial imagery emphasizing sound (niḥsvana) and the violence of combat.
