Matsya Purana — Division of Bhārata-varṣa
सेतुकाः सूतिकाश्चैव कुपथां वाजिवासिकाः नवराष्ट्रा माहिषिकाः कलिङ्गाश्चैव सर्वशः //
setukāḥ sūtikāścaiva kupathāṃ vājivāsikāḥ navarāṣṭrā māhiṣikāḥ kaliṅgāścaiva sarvaśaḥ //
Also mentioned are the Setukas and the Sūtikās; the people of Kupatha and the Vājivāsikas; the Navarāṣṭras, the Māhiṣikas, and likewise the Kaliṅgas—everywhere, in all quarters.
This verse does not discuss Pralaya; it is part of a geographical-ethnographic listing of peoples and regions mentioned in the Matsya Purāṇa.
Indirectly, such catalogues support rājadhrama and governance by identifying recognized peoples/territories; a king’s duty includes knowing lands, boundaries, and communities under protection and taxation.
No direct Vāstu or ritual rule appears in this verse; its significance is contextual—locating communities that later Purāṇic traditions associate with pilgrimage routes, regional temples, and cultural zones.
