Matsya Purana — Paurava Genealogy
सुखीवलसुतश्चापि भावी राजा परिष्णवः परिष्णवसुतश्चापि भविता सुतपा नृपः //
sukhīvalasutaścāpi bhāvī rājā pariṣṇavaḥ pariṣṇavasutaścāpi bhavitā sutapā nṛpaḥ //
And the son of Sukhīvala will become king—Pariṣṇava. And the son of Pariṣṇava will in turn become the ruler named Sutapā.
This verse does not address pralaya; it records royal succession in a dynastic genealogy.
Indirectly, it situates kingship as a hereditary succession (vamsha), providing a historical frame for later teachings on rajadharma by identifying legitimate rulers in sequence.
No Vastu or ritual procedure is mentioned; the focus is purely genealogical (naming successive kings).
