Matsya Purana — Description of Himavat
क्वचित्संस्पृष्टसूर्यांशुं क्वचिच् च तमसावृतम् दरीमुखैः क्वचिद्भीमैः पिबन्तं सलिलं महत् //
kvacitsaṃspṛṣṭasūryāṃśuṃ kvacic ca tamasāvṛtam darīmukhaiḥ kvacidbhīmaiḥ pibantaṃ salilaṃ mahat //
In some places it was touched by the sun’s rays; in other places it was veiled in darkness. And in some fearful regions, through cavern-like mouths, it seemed to be drinking up the vast waters.
It depicts Pralaya-like conditions through unstable light and darkness and a terrifying image of the landscape ‘swallowing’ immense waters—classic Purāṇic language for catastrophic dissolution and inundation.
Indirectly, it reinforces the Matsya Purana’s warning that worldly stability can collapse; hence kings and householders should uphold dharma, prepare through right conduct and charity, and remain detached amid impermanence.
No direct Vāstu or ritual rule is stated; however, the verse’s imagery of cavern-mouths and engulfing waters is often read as a cautionary backdrop for choosing safe, well-drained sites and respecting natural landforms in traditional planning.
