Matsya Purana — Purūravas Beholds the Divine Himalayan River
या हि सुतानिव पाति मनुष्यान् या च युता सततं हिमसंघैः या च युता सततं सुरवृन्दैर् या च जनैः स्वहिताय श्रिता वै //
yā hi sutāniva pāti manuṣyān yā ca yutā satataṃ himasaṃghaiḥ yā ca yutā satataṃ suravṛndair yā ca janaiḥ svahitāya śritā vai //
She who protects human beings as though they were her own sons; she who is ever accompanied by the Himalayan masses of snow; she who is ever attended by hosts of gods; and she whom people resort to for their own welfare—that sacred one is praised here.
This verse is not about pralaya; it is a tirtha-mahatmya style praise describing a sacred river/Devi who protects people and is associated with Himalayan snows and divine attendants.
It supports the dharmic ideal that householders (and rulers who guide them) should seek welfare through righteous means—such as honoring sacred places, maintaining faith, and pursuing public well-being under divine order rather than mere self-interest.
The verse implies ritual significance of a tirtha: people ‘resort’ to it for welfare—suggesting pilgrimage, bathing, and offerings. No specific Vastu or temple-construction rule is stated in this shloka.
