Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
तुषारचयसंछन्नो मन्दरश्चापि पर्वतः उशीरबिन्दुश्च गिरिश् चन्द्रप्रस्थस्तथाद्रिराट् //
tuṣāracayasaṃchanno mandaraścāpi parvataḥ uśīrabinduśca giriś candraprasthastathādrirāṭ //
Also (there is) the mountain Mandara, covered with heaps of snow; and the peaks named Uśīrabindu, Giri, Candraprastha, and Adrīrāṭ as well.
This verse does not describe Pralaya directly; it functions as a sacred-geography catalogue, naming notable mountains/peaks within the Purana’s mapped world.
Indirectly, it supports dharmic life by identifying revered landscapes—useful for pilgrimage (tirtha-yatra), vows, and patronage of sacred places, which are praised duties for kings and householders in Purana-based ethics.
No explicit Vastu or ritual procedure is stated, but such mountain-and-terrain listings commonly inform auspicious site awareness—terrain, elevation, and sacred setting are traditional considerations when selecting locations for temples, hermitages, and rites.
