Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
विहरन्ति रमन्ते च दृश्यमानाश्च तैः सह तत्र पुण्या जनपदाश् चातुर्वर्ण्यसमन्विताः //
viharanti ramante ca dṛśyamānāśca taiḥ saha tatra puṇyā janapadāś cāturvarṇyasamanvitāḥ //
They sport and rejoice there, appearing together with them; and in that place are meritorious provinces and settlements, complete with the four varṇas (social orders).
This verse does not describe Pralaya directly; it highlights an ordered, auspicious human landscape—holy janapadas where beings are seen enjoying—implying stability and dharmic continuity rather than cosmic dissolution.
By praising janapadas “endowed with chaturvarnya,” the verse implies that a righteous king should protect social harmony and ensure each group can perform its duties, while householders sustain dharma through their roles within a well-ordered community.
Architecturally, it points to the ideal of a ‘complete’ settlement—organized communities (janapadas) aligned with dharma—supporting the broader Matsya Purana theme that town planning and civic order should facilitate proper ritual life and social functions.
