Matsya Purana — The Burning of Tripura and Rudra’s Victory
बद्धध्वजपताकानि स्वर्णरौप्यमयानि च गृहाणि तस्मिंस्त्रिपुरे दानवानामुपद्रवे दह्यन्ते दहनाभानि दहनेन सहस्रशः //
baddhadhvajapatākāni svarṇaraupyamayāni ca gṛhāṇi tasmiṃstripure dānavānāmupadrave dahyante dahanābhāni dahanena sahasraśaḥ //
In that Tripura, the houses—adorned with fastened banners and pennants, and fashioned of gold and silver—began to burn in the calamity that befell the Dānavas; countless structures, blazing like fire itself, were consumed by the conflagration.
It does not describe cosmic Pralaya directly; it depicts a localized, divinely-driven destruction—Tripura’s burning—used as Purāṇic imagery for the collapse of adharma and demonic power.
By implication, it warns that wealth and splendid construction (even “gold and silver houses”) are unstable when aligned with adharma; righteous governance and conduct are presented elsewhere in the Purāṇa as the true protection against ruin.
Architecturally, it references urban ornamentation—banners and pennants on buildings—signaling ceremonial display and civic grandeur; ritually, the scene functions as a narrative backdrop for the fire of divine retribution rather than a Vāstu prescription.
