Matsya Purana — Agastya’s Origin
इमं लोकं स चाप्नोति रूपारोग्यसमन्वितः द्वितीयेन भुवर्लोकं स्वर्गलोकं ततः परम् //
imaṃ lokaṃ sa cāpnoti rūpārogyasamanvitaḥ dvitīyena bhuvarlokaṃ svargalokaṃ tataḥ param //
Endowed with beauty and freedom from disease, he attains this world; by the second (merit) he reaches the Bhuvar-loka, and thereafter the Svarga-loka, and then the world beyond that (still higher).
This verse is not about Pralaya; it describes karmic results (phala) as a graded ascent through worlds—earth, Bhuvar-loka, Svarga-loka, and a higher realm beyond—based on accumulated merit.
It supports the Matsya Purana’s dharma framework: by performing righteous duties—such as charity, vows, ritual observances, and protection of subjects—a king or householder gains both worldly well-being (health, good form) and higher posthumous attainments.
No Vāstu or iconographic rule is stated directly; the ritual significance is phala-śruti style teaching—emphasizing that properly performed dharmic acts and observances yield progressively higher spiritual destinations.
