Matsya Purana — Glory of Prayaga: The Fruit of the Anashaka Fast and the Merit of the Yamuna
*मार्कण्डेय उवाच दिष्ट्या ते सफलं जन्म दिष्ट्या ते तारितं कुलम् कीर्तनाद्वर्धते पुण्यं श्रुतात्पापप्रणाशनम् //
*mārkaṇḍeya uvāca diṣṭyā te saphalaṃ janma diṣṭyā te tāritaṃ kulam kīrtanādvardhate puṇyaṃ śrutātpāpapraṇāśanam //
Mārkaṇḍeya said: “Fortunate indeed is your life—your birth has become fruitful; fortunate indeed is your lineage, for it has been carried across to safety. Through recitation, merit increases; through hearing, sins are destroyed.”
This verse does not describe pralaya directly; it teaches a dharmic principle: sacred recitation (kīrtana) builds merit and sacred hearing (śravaṇa) destroys sin—practices often recommended as safeguards in times of moral decline.
It frames a core duty: sustaining dharma through listening to and reciting puranic teachings. For householders and rulers alike, śravaṇa and kīrtana are presented as accessible disciplines that purify conduct (pāpa-kṣaya) and strengthen virtue (puṇya-vṛddhi), thereby uplifting one’s family line.
No architectural rule is stated here; the ritual takeaway is the efficacy of two practices—kīrtana (recitation/praise) and śravaṇa (hearing)—as purificatory acts that generate merit and remove sin.
