Matsya Purana — The Battle for Tripura: Portents
व्रणैरजस्रं क्षतजं वमन्तः कोपोपरक्ता बहुधा नदन्तः गणेश्वरास्ते ऽसुरपुंगवाश्च युध्यन्ति शब्दं च महदुद्गिरन्तः //
vraṇairajasraṃ kṣatajaṃ vamantaḥ kopoparaktā bahudhā nadantaḥ gaṇeśvarāste 'surapuṃgavāśca yudhyanti śabdaṃ ca mahadudgirantaḥ //
Vomiting forth blood endlessly from their wounds, their eyes and faces reddened with rage, roaring in many ways, those captains of the hordes and the foremost of the Asuras fought on—uttering a tremendous din.
This verse does not discuss Pralaya; it is a vivid battlefield depiction emphasizing rage, injury, and the thunderous noise of Asura leaders in combat.
Indirectly, it functions as a Purāṇic cautionary image: unchecked kopa (anger) and violent frenzy lead to destruction and suffering—an ethical contrast to the self-control and measured force expected of righteous rulers and disciplined householders.
No Vāstu or ritual procedure is stated in this verse; its focus is purely narrative—describing the ferocity and soundscape of battle among Asura commanders.
