Matsya Purana — The Burning of Tripura and Rudra’s Victory
गृहैः पतद्भिर्ज्वलनावलीढैर् आसीत्समुद्रे सलिलं प्रतप्तम् कुपुत्रदोषैः प्रहतानुविद्धं यथा कुलं याति धनान्वितस्य //
gṛhaiḥ patadbhirjvalanāvalīḍhair āsītsamudre salilaṃ prataptam kuputradoṣaiḥ prahatānuviddhaṃ yathā kulaṃ yāti dhanānvitasya //
With houses collapsing and being licked by tongues of fire, the ocean’s waters became heated and distressed—just as a prosperous family is struck and pierced through by the faults of an unworthy son.
It depicts Pralaya-like devastation through collapsing, burning dwellings and even the ocean waters becoming heated—an image of the world’s stability breaking down under cosmic upheaval.
By comparing calamity to a family ruined by a ‘kuputra,’ it stresses that inner moral failure can destroy external prosperity—so householders and rulers must cultivate virtue, discipline, and worthy progeny/leadership to protect the lineage and realm.
No direct Vastu or ritual rule is stated; the verse uses the destruction of houses as imagery to emphasize impermanence and the vulnerability of built structures during catastrophic periods.
