Matsya Purana — The Strategy to Defeat Tāraka: Pārvatī’s Birth
सरितः सागराश्चैव समाजग्मुश्च सर्वशः हिमशैलो ऽभवल्लोके तथा सर्वैश्चराचरैः //
saritaḥ sāgarāścaiva samājagmuśca sarvaśaḥ himaśailo 'bhavalloke tathā sarvaiścarācaraiḥ //
Rivers and oceans, from every direction, converged together; and the whole world, along with all moving and unmoving beings, became as though a single Himālaya-like mass.
It depicts a Pralaya-like condition where waters (rivers and oceans) merge and the differentiated world collapses into a single, undivided mass—an image of dissolution and cosmic leveling.
Indirectly, it supports the Purāṇic ethic of preparedness and detachment: rulers and householders should govern and live with awareness of impermanence, using dharma and prudent stewardship rather than assuming the world’s stability is permanent.
No direct Vāstu or ritual rule is stated; however, the verse’s flood-and-convergence imagery is often used in Purāṇic contexts to justify choosing elevated, stable sites (e.g., mountain-like ground) and prioritizing resilience in sacred and civic construction.
