Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
द्विगुणेषु सहस्रेषु योजनानां शतेषु च ग्रहान्तरम् अथैकैकम् ऊर्ध्वं नक्षत्रमण्डलात् //
dviguṇeṣu sahasreṣu yojanānāṃ śateṣu ca grahāntaram athaikaikam ūrdhvaṃ nakṣatramaṇḍalāt //
Above the circle of the nakṣatras (the constellation-sphere), the interval between each planet, one after another in ascending order, is two thousand and two hundred yojanas.
It does not describe pralaya directly; it lays out a cosmological measurement system, specifying the vertical spacing of planetary spheres above the nakṣatra-mandala.
Indirectly, such astronomical measures support calendrical reckoning and auspicious timing (muhūrta) used by kings and householders for governance, rituals, and public ceremonies.
No explicit Vāstu rule is stated, but the verse underpins ritual astronomy—using the ordered cosmic strata that inform temple/altar symbolism and timekeeping for rites.
