Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
नारदो नाम चैवोक्तो दुर्गशैलो महाचितः तत्राचलौ समुत्पन्नौ पूर्वं नारदपर्वतौ //
nārado nāma caivokto durgaśailo mahācitaḥ tatrācalau samutpannau pūrvaṃ nāradaparvatau //
O great-minded one, it is said that there was a mountain named Nārada and another called Durgaśaila. In that very place, two peaks first arose, formerly known as the twin Nārada mountains.
It does not describe Pralaya directly; instead, it preserves a sacred-geography tradition about how specific mountains (Nārada and Durgaśaila) were named and how twin peaks were said to have arisen at a particular site.
Indirectly, it supports the Purāṇic duty of rulers and householders to honor tīrthas and sacred landscapes—maintaining pilgrimage routes, protecting holy sites, and sponsoring worship connected to renowned mountains and their legends.
The verse is primarily toponymic (naming) and geographic; ritually, such named mountains often function as tīrthas where vows, worship, and donations are prescribed in surrounding passages, and architecturally they can be focal points for hill-temples and shrine placement in Puranic tradition.
