Matsya Purana — Description of Himavat
देवदारुवनैर्नीलैः कृताधोवसनं शुभम् मेघोत्तरीयकं शैलं ददृशे स नराधिपः //
devadāruvanairnīlaiḥ kṛtādhovasanaṃ śubham meghottarīyakaṃ śailaṃ dadṛśe sa narādhipaḥ //
That king beheld a mountain, auspicious in aspect: its lower slopes seemed clothed in dark-blue deodāra forests, and its upper region appeared draped in a mantle of clouds.
This verse is not about Pralaya; it is a sacred-geography style description highlighting auspicious natural features—forests and cloud-capped peaks—often used in the Purāṇas to mark holy terrain.
It presents the king as observant and responsive to auspicious surroundings—an implied royal virtue in Purāṇic ethics: to recognize sacred landscapes, undertake righteous journeys (yātrā), and honor places conducive to dharma.
No explicit Vāstu rule is stated, but the imagery encodes ritual-auspicious markers: a stable, forested mountain with cloud “garments” suggests a sanctified setting suitable for tīrtha visitation, tapas, or the placement of shrines in later contextual passages.
