Matsya Purana — Kailasa
आयतास्ते महाशैलाः समुद्रं दक्षिणं प्रति चक्रमैनाकयोर्मध्ये दिवि सन् दक्षिणापथे //
āyatāste mahāśailāḥ samudraṃ dakṣiṇaṃ prati cakramainākayormadhye divi san dakṣiṇāpathe //
Those great mountain ranges stretch toward the southern ocean; and in Dakṣiṇāpatha, as though standing in the sky, they lie between Cakra and Maināka.
This verse is not about pralaya; it belongs to the Matsya Purana’s cosmographic mapping of the world, describing how mountain ranges are oriented toward the southern ocean within Dakṣiṇāpatha.
Indirectly, such geographic catalogues underpin pilgrimage routes, regional identities, and the idea of dharmic space; a king’s duty includes protecting territories and sacred routes, while householders use such knowledge to orient travel, vows, and tīrtha-observances.
The verse does not give direct Vāstu rules, but its emphasis on direction (south/Dakṣiṇāpatha) reflects the broader Purāṇic habit of linking ritual and sacred activity to orientation—useful background for Vāstu-informed site selection and directional sanctity.
