Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
सर्वा मणिमयी भूमिः सूक्ष्मा काञ्चनवालुका सर्वत्र सुखसंस्पर्शा निःशब्दाः पवनाः शुभाः //
sarvā maṇimayī bhūmiḥ sūkṣmā kāñcanavālukā sarvatra sukhasaṃsparśā niḥśabdāḥ pavanāḥ śubhāḥ //
The ground there is entirely gem-like; its sand is fine and golden. Everywhere it is pleasant to the touch, and the auspicious breezes move about noiselessly.
This verse is not describing Pralaya directly; instead it depicts an ideal, purified realm/terrain where the very elements (earth, sand, wind) are auspicious—imagery often used in Puranic cosmology to contrast ordinary worlds with higher, perfected spaces.
By highlighting auspicious environmental qualities—pleasant ground, fine sand, and calm winds—it supports the Matsya Purana’s broader ethic that rulers and householders should choose and maintain wholesome, well-sited settlements and ritual spaces for public welfare and dharmic living.
The verse functions like a vastu indicator: ideal land is smooth/pleasant to touch, refined (fine sand), and free from harsh noise or disruptive winds—traits aligned with selecting a temple or sacred precinct site that is naturally ‘śubha’ (auspicious).
