Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
आनन्दाश्च सुखाश्चैव क्षेमकाश्च नवैः सह वर्णाश्रमाचारयुता देशास्ते सप्त विश्रुताः //
ānandāśca sukhāścaiva kṣemakāśca navaiḥ saha varṇāśramācārayutā deśāste sapta viśrutāḥ //
Ānanda, Sukha, and Kṣemaka—together with nine others—are regions endowed with the observances of varṇa and āśrama; these are the seven famed lands.
This verse does not describe pralaya directly; it classifies famed regions by their adherence to varṇāśrama conduct, reflecting the post-creation ordering of the world through dharma.
By praising lands “endowed with varṇāśrama practice,” it implies that a king should protect social and ritual order, and householders should sustain their āśrama duties—together forming the mark of a stable, ‘secure’ realm.
The verse signals a ritual-civilizational ideal: settlements are considered exemplary when they support varṇāśrama-ācāra—an underlying principle often paired in the Matsya Purana with orderly town planning, temple rites, and socially supported worship.
