Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
मध्ये तस्य महामेरुर् विधूम इव पावकः वेद्यर्धं दक्षिणं मेरोर् उत्तरार्धं तथोत्तरम् //
madhye tasya mahāmerur vidhūma iva pāvakaḥ vedyardhaṃ dakṣiṇaṃ meror uttarārdhaṃ tathottaram //
At its center stands the great Mount Meru, like a smokeless fire. Of the Vedi (the cosmic altar‑region), one half lies to the south of Meru, and likewise the other half lies to the north.
This verse is cosmographic rather than pralaya-focused: it fixes Meru as the central axis and describes a structured division of the cosmic region (vedi) into southern and northern halves.
By presenting an ordered cosmic model (center, north, south), it underwrites dharmic governance and household ritual orientation—kings and householders are expected to align settlements, rites, and boundaries with sacred order and proper directional division.
The term “vedi” suggests an altar-like plan: Meru functions as the central pivot, and the space is conceptually laid out into north and south halves—an idea echoed in Vastu planning where the center and cardinal directions govern layout and ritual placement.
