Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
भद्राश्वं भारतं चैव केतुमालं च पश्चिमे उत्तराश्चैव कुरवः कृतपुण्यप्रतिश्रयाः //
bhadrāśvaṃ bhārataṃ caiva ketumālaṃ ca paścime uttarāścaiva kuravaḥ kṛtapuṇyapratiśrayāḥ //
Bhadrāśva and Bhārata, and also Ketumāla in the west; likewise the Northern Kurus—these are dwellings and sacred refuges for those whose merit has already been fulfilled.
This verse is not about Pralaya; it belongs to cosmography, listing earthly regions (varṣas) and describing them as merit-linked abodes rather than narrating dissolution.
Indirectly, it frames geography in moral terms: one’s puṇya (merit) determines one’s ‘abode’ or favorable realm, reinforcing the Purāṇic ethic that righteous conduct and dharma-oriented life lead to higher, auspicious stations.
No Vāstu or ritual procedure is specified here; the significance is sacred geography—identifying regions revered in Purāṇic cosmology, often used as a backdrop for pilgrimage, cosmological teaching, and merit doctrine.
