Matsya Purana — Kailasa
ततस्तु नलिनी चापि प्राचीमेव दिशं ययौ कुपथान्प्लावयन्ती सा इन्द्रद्युम्नसरांस्यपि //
tatastu nalinī cāpi prācīmeva diśaṃ yayau kupathānplāvayantī sā indradyumnasarāṃsyapi //
Then the river Nalinī, too, flowed eastward, flooding the misguided channels and even inundating the lakes of Indradyumna.
It does not describe cosmic Pralaya directly; it uses flood imagery at a local, geographical scale—showing a river overflowing and submerging channels and sacred lakes.
Indirectly, it implies the importance of managing waterways and respecting sacred landscapes; a king’s dharma includes protecting tirthas, lakes, and proper watercourses from destructive overflow.
The verse highlights hydrology around sacred sites: for Vastu and temple-town planning, correct water-channel alignment and drainage are crucial, since misdirected courses (kupatha) can lead to inundation of tanks and ritual water-reservoirs.
