Matsya Purana — The Battle at Tripura: Shiva’s Strategy
ते तस्मिंस्त्रिपुरे दैत्या नद्यः सिन्धुपताविव विशन्ति क्रुद्धवदना वल्मीकमिव पन्नगाः //
te tasmiṃstripure daityā nadyaḥ sindhupatāviva viśanti kruddhavadanā valmīkamiva pannagāḥ //
There, in that Tripura, the Daityas entered—faces contorted with rage—like rivers flowing into the lord of rivers (the ocean), or like serpents slipping into an anthill (valmīka).
It does not describe Pralaya directly; instead, it uses cosmic-scale imagery (rivers entering the ocean) to convey the Daityas’ mass movement and inevitability as they pour into Tripura.
Indirectly, it highlights the danger of anger-driven collectives (“kruddha-vadanāḥ”): a king is cautioned to anticipate and contain hostile forces before they consolidate into a fortified base, and a householder is advised to restrain wrath that rushes in like an unstoppable current.
Architecturally, “Tripura” functions as an image of a fortified, engineered stronghold; the verse emphasizes how a well-known ‘city/fort’ becomes a locus where forces gather—useful for interpreting Matsya Purana themes around protected settlements and strategic enclosure (though no direct Vastu rule is stated here).
