Matsya Purana — Dhruva as Cosmic Pivot: Motions of Sun–Moon–Planets
सैष भ्रमन्भ्रामयते चन्द्रादित्यौ ग्रहैः सह भ्रमन्तमनुसर्पन्ति नक्षत्राणि च चक्रवत् //
saiṣa bhramanbhrāmayate candrādityau grahaiḥ saha bhramantamanusarpanti nakṣatrāṇi ca cakravat //
This itself (cosmic power/time), while revolving, causes the Moon and the Sun—together with the planets—to revolve; and as it moves, the nakṣatras also follow it, circling like a wheel.
It highlights the governing principle (often understood as Kāla—Time, or a cosmic regulator) that drives the orderly revolution of the luminaries; such ordered motion is a hallmark of cosmic maintenance between creations and dissolutions, rather than a direct description of Pralaya itself.
By grounding dharma in cosmic order: just as the Sun, Moon, planets, and nakṣatras move in disciplined cycles, a king and householder are expected to align actions (ritual timing, vows, governance) with regulated time—days, months, seasons, and auspicious nakṣatra-based calendars.
Ritually, it supports nakṣatra- and graha-based timing for rites (saṃskāras, donations, temple consecrations). Architecturally (Vāstu), it underpins orientation and calendrical selection of muhūrtas—linking temple directions and consecration schedules to the perceived wheel-like motion of the heavens.
