Matsya Purana — Description of Himavat
नदीप्रवाहसंजातमहाशब्दैः समन्ततः असंश्रुतान्यशब्दं तं शीततोयं मनोरमम् //
nadīpravāhasaṃjātamahāśabdaiḥ samantataḥ asaṃśrutānyaśabdaṃ taṃ śītatoyaṃ manoramam //
All around, the mighty roar born of the river’s rushing current drowned out every other sound; that cool-water stream was exceedingly delightful.
This verse is not about Pralaya; it is a poetic description of a river whose powerful current creates a continuous roar, emphasizing sacred landscape ambiance rather than cosmic dissolution.
Indirectly, it supports Purāṇic ideals of pilgrimage and reverence for tīrthas: a householder or king who protects waterways, supports tīrtha access, and honors sacred landscapes accrues religious merit and public welfare.
No explicit Vāstu or temple rule is stated, but such river descriptions commonly indicate an auspicious setting for tīrtha-bathing, riverside rites, and the ideal placement of ghāṭas or shrines near cool, flowing water.
