Matsya Purana — Intermediate Dissolution
त्वया सार्धमिदं विश्वं स्थास्यत्यन्तरसंक्षये एवमेकार्णवे जाते चाक्षुषान्तरसंक्षये //
tvayā sārdhamidaṃ viśvaṃ sthāsyatyantarasaṃkṣaye evamekārṇave jāte cākṣuṣāntarasaṃkṣaye //
മന്വന്തരാന്ത്യ സംക്ഷയത്തിൽ ഈ സർവ്വവിശ്വവും നിന്നോടൊപ്പം നിലനിൽക്കും; അതുപോലെ ചാക്ഷുഷ മന്വന്തരക്ഷയത്തിൽ ഏകാർണവ പ്രളയം ഉയർന്നാലും ഇത് നിന്നോടൊപ്പം സംരക്ഷിതമാകും.
It describes the Manvantara-ending dissolution where the world becomes an ekārṇava (a single ocean), yet is preserved to endure through Manu under Matsya’s protection.
By placing preservation of the world’s continuity alongside Manu, it reinforces the Purāṇic ideal that righteous leadership safeguards society through crises—maintaining order, lineage, and sacred knowledge for renewal after calamity.
No direct Vāstu or ritual procedure is stated; the takeaway is cosmological—ritual and sacred traditions are implied to be preserved through the deluge so they can be re-established in the renewed age.
