Matsya Purana — Dhruva as Cosmic Pivot: Motions of Sun–Moon–Planets
शीकरान् सम्प्रमुञ्चन्ति नीहार इति स स्मृतः दक्षिणेन गिरिर्यो ऽसौ हेमकूट इति स्मृतः //
śīkarān sampramuñcanti nīhāra iti sa smṛtaḥ dakṣiṇena giriryo 'sau hemakūṭa iti smṛtaḥ //
That which releases fine sprays of water is called “nīhāra” (mist). And to the south, the mountain there is known as Hemakūṭa.
This verse is not about Pralaya; it belongs to the Matsya Purāṇa’s cosmography, defining a natural phenomenon (nīhāra, mist) and naming the southern mountain Hemakūṭa.
Indirectly, it supports dharma through knowledge of sacred geography—important for rulers and householders in planning pilgrimages, ritual journeys, and understanding the Purāṇic map of the world.
No direct Vāstu rule is stated; however, such geographic markers are used in Purāṇic tradition to orient sacred space and contextualize tīrtha-yātrā and regional ritual identities.
