Matsya Purana — The Battle for Tripura: Portents
व्रणाननैर् अङ्गरसं स्रवद्भिः सुरासुरैर्नक्रतिमिङ्गिलैश्च कृतो मुहूर्तेन समुद्रदेशः सरक्ततोयः समुदीर्णतोयः //
vraṇānanair aṅgarasaṃ sravadbhiḥ surāsurairnakratimiṅgilaiśca kṛto muhūrtena samudradeśaḥ saraktatoyaḥ samudīrṇatoyaḥ //
In but a single muhūrta, the ocean-region became a scene of upheaval—its waters churned and swollen, reddened with blood—filled with gods and asuras whose wounded mouths streamed bodily fluid, and with creatures like crocodiles and the timiṅgila sea-monsters.
It portrays Pralaya-like chaos through a violently heaving ocean, blood-reddened waters, and beings (devas, asuras, and sea-monsters) thrown into turmoil—an emblem of cosmic order collapsing into agitation.
Indirectly, it functions as a warning-image: when the world becomes unstable and dangerous, dharma emphasizes preparedness, self-restraint, and reliance on divine guidance—virtues highlighted in the broader Matsya–Manu narrative even if not legislated in this single verse.
No explicit Vāstu or ritual procedure is taught in this verse; its significance is primarily cosmological and narrative, supplying vivid Pralaya imagery rather than temple-building or rite-instructions.
