Matsya Purana — Dhruva as Cosmic Pivot: Motions of Sun–Moon–Planets
अशीतिमण्डलशतं काष्ठयोरुभयोश्चरन् ध्रुवेण मुच्यमानेन पुना रश्मियुगेन च //
aśītimaṇḍalaśataṃ kāṣṭhayorubhayoścaran dhruveṇa mucyamānena punā raśmiyugena ca //
Moving through one hundred and eighty circular courses along both solstitial paths, it is set in motion by Dhruva, and again by the paired yoke of rays.
This verse is not describing pralaya; it presents a cosmological/astronomical model where celestial motion is regulated around Dhruva and driven by the sun’s rays.
Indirectly, it supports dharma through timekeeping: understanding solar courses underpins calendrical reckoning for rites, festivals, taxation seasons, and orderly governance.
Ritually, it relates to fixing auspicious timings (muhūrta) and seasonal observances; architecturally, such cosmological orientation can inform temple alignment and calendrical consecration schedules rather than giving direct Vāstu rules.
