Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
स तु मेरुः परिवृतो भुवनैर्भूतभावनैः यस्येमे चतुरो देशा नानापार्श्वेषु संस्थिताः //
sa tu meruḥ parivṛto bhuvanairbhūtabhāvanaiḥ yasyeme caturo deśā nānāpārśveṣu saṃsthitāḥ //
That Mount Meru is encircled by the worlds—those that nurture all beings; and upon its various sides are situated these four regions (quarters).
This verse is not about Pralaya; it outlines stable cosmic geography—Meru as the central axis, encircled by life-sustaining realms, with four regions positioned around it.
Indirectly, it frames the ordered universe (dik and deśa arrangement) that underlies dharmic life—ritual orientation, governance by quarters, and the idea that worldly order mirrors cosmic order.
By emphasizing quarters and sidedness around a central axis (Meru), it supports Vastu and ritual principles of orientation (dik-nirṇaya): placing structures/altars with reference to cardinal regions and a central bindu.
