Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
प्रजापतिगिरिश्चैव तथा पुष्करपर्वतः देवाभ्रपर्वतश्चैव तथा वै रेणुको गिरिः //
prajāpatigiriścaiva tathā puṣkaraparvataḥ devābhraparvataścaiva tathā vai reṇuko giriḥ //
Likewise (there are) Prajāpati Mountain, and also Puṣkara Mountain; Devābhra Mountain as well, and indeed the mountain called Reṇuka.
This verse does not describe Pralaya; it functions as a sacred-geography catalogue, naming mountains regarded as holy within the Matsya Purana’s tirtha-mahātmya context.
Indirectly, it supports dharma through pilgrimage culture: kings and householders are encouraged in Purāṇic ethics to honor tirthas, sponsor travel/rituals, and cultivate merit (puṇya) by visiting or venerating such sacred places.
The verse itself names mountains rather than giving building rules; ritually, such sites typically imply tirtha-darśana, bathing, offerings, and worship performed at or near these sacred mountains—common Matsya Purana tirtha practices.
