Matsya Purana — Bhīma-Dvādaśī
य इदमघविदारणं शृणोति भक्त्या परिपठतीह परोपकारहेतोः तिथिमिह सकलार्थभाङ्नरेन्द्रस् तव चतुरानन साम्यतामुपैति //
ya idamaghavidāraṇaṃ śṛṇoti bhaktyā paripaṭhatīha paropakārahetoḥ tithimiha sakalārthabhāṅnarendras tava caturānana sāmyatāmupaiti //
Whoever, with devotion, listens to this “Sin-destroying” hymn and recites it here for the sake of benefiting others—such a king, endowed with every prosperity in this world, attains equality with the Four-faced (Brahmā) through your grace.
This verse is not a Pralaya narrative; it is a phalaśruti stating the merit gained by devoted hearing and recitation—especially the removal of sin and attainment of exalted status.
It highlights a king’s dharmic role: practicing devotion not only for personal merit but explicitly “for the benefit of others” (paropakāra), which aligns with the Purāṇic ideal of welfare-oriented rulership.
No Vāstu or temple-building rule is stated here; the ritual takeaway is the efficacy of śravaṇa (hearing) and pāṭha (recitation) performed with bhakti and altruistic intent.
