Matsya Purana — Paurava Genealogy
सुधन्वनस्तु दायादः पुत्रो मतिमतां वरः च्यवनस्तस्य पुत्रस्तु राजा धर्मार्थतत्त्ववित् //
sudhanvanastu dāyādaḥ putro matimatāṃ varaḥ cyavanastasya putrastu rājā dharmārthatattvavit //
Sudhanvan was his heir—an outstanding son among the wise. His son, Cyavana, was a king who understood the true principles of dharma and artha.
This verse does not discuss pralaya; it is part of a genealogical succession, highlighting heirs and the ethical qualifications of kings.
By praising Cyavana as a knower of dharma and artha, the verse frames ideal kingship as grounded in righteous duty (dharma) and sound governance/prosperity (artha), a core Rajadharma theme in the Matsya Purana.
No vastu, temple-building, or ritual procedure is mentioned; the focus is royal lineage and the moral-intellectual stature of rulers.
