Matsya Purana — Paurava Genealogy
हुत्वाग्निं विधिवत्सम्यक् पवित्रीकृतभोजना अग्निहोत्रक्रमेणैव सा सुष्वाप महाव्रता //
hutvāgniṃ vidhivatsamyak pavitrīkṛtabhojanā agnihotrakrameṇaiva sā suṣvāpa mahāvratā //
Having duly offered into the sacred fire in full accordance with the rite, and having taken food that was ritually purified, she—steadfast in the great vow—then lay down to sleep, following the proper sequence of the Agnihotra.
This verse does not address Pralaya; it focuses on disciplined daily ritual life—proper fire-offering, purified food, and observance of the Agnihotra order.
It reflects gṛhastha-dharma: performing Agnihotra correctly, maintaining ritual purity in eating, and following prescribed daily sequences—core duties for householders (and exemplary conduct for rulers supporting Vedic order).
The ritual significance is the strict “krama” (sequence) of Agnihotra and the emphasis on pavitrīkṛta (purified) food—highlighting procedural correctness and purity as essential components of Vedic fire worship.
