Matsya Purana — Conclusion of the Prayaga Mahatmya: Kingship Restored
*सूत उवाच एवमुक्त्वाथ नन्दीशस् तत्रैवान्तरधीयत नारदो ऽपि जगामाशु प्रयागाभिमुखस्तथा //
*sūta uvāca evamuktvātha nandīśas tatraivāntaradhīyata nārado 'pi jagāmāśu prayāgābhimukhastathā //
Sūta said: Having spoken thus, Nandīśa vanished right there; and Nārada too quickly set off, facing toward Prayāga.
This verse does not address pralaya; it marks a narrative transition where Nandīśa disappears and Nārada proceeds toward the sacred tīrtha of Prayāga.
Indirectly, it supports the Purāṇic ethic of tīrtha-yātrā (pilgrimage) and seeking merit through sacred places—an approved dharmic practice for householders when performed with right intent.
No vāstu or temple-building rule is stated; the ritual takeaway is the emphasis on Prayāga as a destination worthy of approach, implying the importance of tīrtha-oriented rites and pilgrimage observances.
