Matsya Purana — Emergence of Brahmā from the Golden Lotus and the Lotus-Form Earth
यानि पद्मस्य पर्णानि भूरीणि तु नराधिप ते दुर्गमाः शैलचिता म्लेच्छदेशा विकल्पिताः //
yāni padmasya parṇāni bhūrīṇi tu narādhipa te durgamāḥ śailacitā mlecchadeśā vikalpitāḥ //
O king, just as a lotus has many leaves, so too are there many regions—conceived as difficult to access—mountain-strewn tracts and the lands of the Mlecchas, set apart in this division.
This verse is not about Pralaya; it belongs to the Matsya Purana’s cosmography, classifying terrestrial regions as numerous and often difficult to traverse (especially mountainous and frontier lands).
By addressing the ruler (“narādhipa”), it frames geography as practical knowledge for governance—understanding remote, rugged, and frontier territories (including mleccha regions) relevant to diplomacy, security, and administration.
No direct Vāstu/ritual rule is stated; the main takeaway is spatial classification of lands, which can indirectly inform settlement planning and statecraft in later Vāstu or administrative contexts.
