Matsya Purana — Prayaga Mahatmya: Trimurti Presence
कल्पान्ते तत्समग्रं हि रुद्रः संहरते जगत् तदा प्रयागतीर्थं च न कदाचिद्विनश्यति //
kalpānte tatsamagraṃ hi rudraḥ saṃharate jagat tadā prayāgatīrthaṃ ca na kadācidvinaśyati //
At the end of a kalpa, Rudra indeed withdraws (dissolves) this entire world; yet even then, the sacred ford of Prayāga never perishes at any time.
It states that at kalpa’s end Rudra performs cosmic dissolution of the whole world, yet certain sacred loci like Prayāga are described as imperishable, emphasizing tirthas as transcendent anchors amid pralaya.
By highlighting Prayāga’s unfailing sanctity, it supports the dharmic duty of kings and householders to uphold pilgrimage, charity, and ritual observances at tirthas—acts believed to yield enduring merit even when worldly conditions are unstable.
Ritually, it elevates Prayāga as an eternally valid site for snāna (sacred bathing), śrāddha, and dāna; architecturally, it implies the enduring primacy of tirtha-zones (ghats, shrines, yajña spaces) as sacred planning centers in Puranic temple-and-pilgrimage culture.
