Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
सर्वेषां तु ग्रहाणां वै सूर्यो ऽधस्तात्प्रसर्पति विस्तीर्णं मण्डलं कृत्वा तस्योर्ध्वं चरते शशी //
sarveṣāṃ tu grahāṇāṃ vai sūryo 'dhastātprasarpati vistīrṇaṃ maṇḍalaṃ kṛtvā tasyordhvaṃ carate śaśī //
Among all the heavenly bodies, the Sun moves below, spreading forth and forming a broad circular sphere (maṇḍala); above that solar sphere the Moon moves.
This verse is not about pralaya; it gives a cosmological mapping of celestial motion, placing the Sun’s sphere below and the Moon’s path above it.
By describing Sun–Moon movement, it supports calendrical and auspicious-time (muhūrta/tithi) reckoning used by kings and householders for governance, sacrifices, vows, and public rituals.
Indirectly, it underpins ritual scheduling: temple worship, homa, and consecrations rely on lunar and solar calculations; the verse frames the Sun–Moon spheres that guide such timing.
