किंसंज्ञश्चैव भगवांल् लोके विज्ञायसे प्रभो तर्कये त्वां महात्मानं को ह्यन्यः स्थातुमर्हति //
kiṃsaṃjñaścaiva bhagavāṃl loke vijñāyase prabho tarkaye tvāṃ mahātmānaṃ ko hyanyaḥ sthātumarhati //

It frames the Pralaya episode as a revelation of divine supremacy: Manu recognizes that only the Supreme Lord could perform the extraordinary acts associated with the deluge narrative.
Manu models discernment (tarka) joined with reverence—an ideal for rulers and householders in the Matsya Purana: to inquire humbly, recognize true authority, and align conduct with dharma under divine guidance.
No direct Vastu or ritual procedure is stated; the verse is theological and dialogic, focusing on naming/recognition of the Lord rather than temple architecture rules.
