Matsya Purana — Bhīma-Dvādaśī
त्वमादिकर्ता भव सौकरे ऽस्मिन् कल्पे महावीरवरप्रधान यस्याः स्मरन्कीर्तनमप्यशेषं विनष्टपापस्त्रिदशाधिपः स्यात् //
tvamādikartā bhava saukare 'smin kalpe mahāvīravarapradhāna yasyāḥ smarankīrtanamapyaśeṣaṃ vinaṣṭapāpastridaśādhipaḥ syāt //
In this Saukara Kalpa, be the primordial initiator—O foremost among the greatest heroes. By remembering Her and even singing Her praise, one’s sins are entirely destroyed, and one may become the lord of the thirty gods (Indra).
It situates the praise within a specific cosmic cycle (the Saukara Kalpa) and invokes a “primordial creator,” but it does not directly describe Pralaya; the emphasis is devotional efficacy within a Kalpa framework.
It promotes smaraṇa (remembrance) and kīrtana (praise/recitation) as accessible disciplines that purify wrongdoing—practices recommended for householders and rulers alike to maintain ethical clarity and merit.
No Vāstu or temple-building rule is stated; the ritual takeaway is the power of kīrtana/smaraṇa as a purificatory act capable of granting high divine status (Indrahood) in Puranic merit logic.
