Matsya Purana — The Cave-Sanctuary: Jewel-Lake
नानाविधैस्तथा पुष्पैः फलमूलैः सगोरसैः नित्यं त्रिषवणस्नायी वह्निपूजापरायणः //
nānāvidhaistathā puṣpaiḥ phalamūlaiḥ sagorasaiḥ nityaṃ triṣavaṇasnāyī vahnipūjāparāyaṇaḥ //
With many kinds of flowers, and with fruits and roots along with cow-derived offerings, he should bathe regularly at the three daily junctions and remain devoted to the worship of the sacred fire.
This verse is not about pralaya; it prescribes daily discipline—regular bathing at the three savanas and steadfast worship of the sacred fire.
It reflects the expected ācāra of a dhārmika leader or gṛhastha: maintaining purity through tri-savana bathing and sustaining Vedic order through Agni-worship and suitable offerings (flowers, fruits, roots, and cow-derived substances).
Ritually, it emphasizes Agni-pūjā/Agnihotra-style fire worship and prescribed upacāras (offerings). Indirectly, it implies the presence of a maintained household/altar fire space, central to orthodox domestic ritual practice.
