Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
नर्मदा शुभतोया च तथा वेत्रवती नदी गोमती गोकुलाकीर्णा तथा पूर्वसरस्वती //
narmadā śubhatoyā ca tathā vetravatī nadī gomatī gokulākīrṇā tathā pūrvasarasvatī //
The Narmadā, whose waters are auspicious; the river Vetravatī; the Gomati—thronged with cowherd-settlements—and likewise the ancient (eastern) Sarasvatī.
This verse is not a pralaya (cosmic dissolution) passage; it functions as sacred geography, naming revered rivers whose waters and associations are praised for religious merit.
By highlighting holy rivers, it supports householders’ and rulers’ dharma through tirtha-yatra, bathing, and offerings—acts traditionally encouraged for purification, charity, and maintaining social-religious order.
Ritually, these rivers indicate preferred locales for snāna (sacred bathing), tarpana, and dāna; indirectly, such rivers are also classical markers for selecting auspicious temple/settlement sites near pure water sources.
