Matsya Purana — Lineage of Yayāti through Yadu and the Deeds of Kārtavīrya Arjuna
न तस्य वित्तनाशः स्यान् नष्टं च लभते पुनः कार्तवीर्यस्य यो जन्म कथयेदिह धीमतः यथावत्स्विष्टपूतात्मा स्वर्गलोके महीयते //
na tasya vittanāśaḥ syān naṣṭaṃ ca labhate punaḥ kārtavīryasya yo janma kathayediha dhīmataḥ yathāvatsviṣṭapūtātmā svargaloke mahīyate //
For him there will be no loss of wealth, and what has been lost he obtains again. Whoever, with understanding, properly recounts here the birth of the wise Kārtavīrya—his soul purified as though by well-performed sacrifices—becomes honored in the heavenly world.
This verse does not discuss Pralaya; it is a phalaśruti promising worldly prosperity and heavenly merit for properly recounting Kārtavīrya’s birth narrative.
It frames Purāṇic listening/recitation as a dharmic household practice: preserving sacred history (vamśa-kathā) is said to yield prosperity (no loss of wealth, recovery of losses) and spiritual purification akin to correctly performed yajñas.
No Vāstu or temple-rule detail appears here; the ritual idea is comparative—recitation done “yathāvat” purifies the narrator like a “well-offered sacrifice” (sviṣṭa), highlighting correctness of performance.
