स्वचक्षुःसदृशैः पुष्पैः संछन्ने नलिनीवने छन्ना काचिच् चिरात्प्राप्ता कान्तेनान्विष्य यत्नतः //

In a lotus-grove thickly covered with blossoms like her own eyes, a certain woman lay hidden; after a long while, her beloved—searching with great effort—found her at last.
This verse is not about Pralaya; it uses poetic nature-imagery (a lotus-grove and blossoms) to depict concealment and eventual discovery in a human-scale narrative.
Indirectly, it highlights perseverance and focused effort (yatnataḥ) in fulfilling one’s commitment—qualities praised for householders and rulers alike, though the verse itself is primarily descriptive rather than prescriptive.
No explicit Vastu or ritual rule appears here; the key takeaway is the setting (nalinīvana), a natural grove used as a narrative backdrop rather than a technical architectural specification.
