Matsya Purana — Dhruva as Cosmic Pivot: Motions of Sun–Moon–Planets
अहर्नाभिस्तु सूर्यस्य एकचक्रस्य वै स्मृतः अराः संवत्सरास्तस्य नेम्यः षडृतवः स्मृताः //
aharnābhistu sūryasya ekacakrasya vai smṛtaḥ arāḥ saṃvatsarāstasya nemyaḥ ṣaḍṛtavaḥ smṛtāḥ //
In the Sun’s single wheel, the day is remembered as the hub; its spokes are the years, and its rim is known to be the six seasons.
It does not describe Pralaya directly; it presents a stable cosmological model of time (kāla) as a solar wheel, emphasizing orderly cycles rather than dissolution.
By framing time as an ordered cycle of day, year, and seasons, it supports dharmic planning—performing rites, agriculture, governance, and vows in their proper seasonal and calendrical timings.
Ritually, it underlines correct kāla (timing) for ceremonies aligned with seasons; architecturally (Vastu practice), it reinforces solar/time orientation principles used to schedule consecrations and select auspicious periods.
