Matsya Purana — The Ravi-Śayana
इदं वसिष्ठेन पुरार्जुनेन कृतं कुबेरेण पुरंदरेण यत्कीर्तनेनाप्यखिलानि नाशम् आयान्ति पापानि न संशयो ऽस्ति //
idaṃ vasiṣṭhena purārjunena kṛtaṃ kubereṇa puraṃdareṇa yatkīrtanenāpyakhilāni nāśam āyānti pāpāni na saṃśayo 'sti //
This (hymn) was composed by Vasiṣṭha, by Purārjuna, by Kubera, and by Purandara; by merely reciting it, all sins are destroyed—of this there is no doubt.
It does not address pralaya directly; it emphasizes moral purification—sins are said to be destroyed through kīrtana (devotional recitation), a recurring Purāṇic method for restoring dharmic order in any age.
It frames kīrtana as a practical dharma for all—kings and householders alike—because regular recitation and praise are presented as a means to cleanse pāpa and sustain righteous conduct (ācāra).
No Vāstu/temple-building rule is stated here; the ritual takeaway is the potency of stotra-kīrtana itself—recitation is treated as a purificatory rite with papa-nāśana (sin-destroying) fruit.
