Matsya Purana — Dhruva as Cosmic Pivot: Motions of Sun–Moon–Planets
दह्यमानेषु तेष्वेव जङ्गमस्थावरेषु च धूमभूतास्तु ता ह्यापो निष्क्रामन्तीह सर्वशः //
dahyamāneṣu teṣveva jaṅgamasthāvareṣu ca dhūmabhūtāstu tā hyāpo niṣkrāmantīha sarvaśaḥ //
As those very beings—both moving and unmoving—are being scorched, the waters within them, having turned into smoke, stream forth everywhere from all sides.
It depicts an advanced stage of dissolution where living and non-living forms are scorched, and the internal element of water is forced out as vapour/smoke—an image of the elements breaking down and withdrawing from embodied forms.
Indirectly, it reinforces the Matsya Purana’s ethic of detachment: kings and householders should govern and live righteously while remembering impermanence, since even the world’s stable and moving beings are subject to dissolution.
No direct Vastu or ritual rule is stated; the takeaway is cosmological—fire/heat dries and expels moisture—often echoed in ritual symbolism where heat transforms offerings and represents elemental transmutation.
