Matsya Purana — The Greatness of Prayaga: Manasa Tirtha
*मार्कण्डेय उवाच शृणु राजन्प्रयागस्य माहात्म्यं पुनरेव तु यच्छ्रुत्वा सर्वपापेभ्यो मुच्यते नात्र संशयः //
*mārkaṇḍeya uvāca śṛṇu rājanprayāgasya māhātmyaṃ punareva tu yacchrutvā sarvapāpebhyo mucyate nātra saṃśayaḥ //
Mārkaṇḍeya said: Listen, O King, once again to the greatness of Prayāga; by hearing it, one is freed from all sins—of this there is no doubt.
This verse does not discuss pralaya; it introduces the tīrtha-māhātmya of Prayāga and emphasizes moral purification (release from sin) through hearing its sacred account.
By addressing the listener as “O King,” the text frames dharmic leadership as grounded in śravaṇa (hearing sacred teachings) and promoting pilgrimage culture and ethical purification—values a king/householder is expected to uphold and support.
No vastu or temple-architecture rule is stated here; the ritual takeaway is that attentive hearing of Prayāga’s māhātmya itself is treated as a purificatory act leading to pāpa-kṣaya (diminution of sin).
