Matsya Purana — Paurava Genealogy
येषु वै स्थास्यते क्षत्रम् उत्पत्स्यन्ते नृपाश्च ये तेषाम् आयुष्प्रमाणं च नामतश्चैव तान्नृपान् //
yeṣu vai sthāsyate kṣatram utpatsyante nṛpāśca ye teṣām āyuṣpramāṇaṃ ca nāmataścaiva tānnṛpān //
“In which lines the Kṣatriya power will endure, and which kings will arise—tell those kings by name, along with the measure of their lifespans.”
This verse does not discuss Pralaya; it shifts to royal chronology—asking which Kshatriya lineages will endure and which kings will be born, including their lifespans.
Indirectly, it frames kingship as a dharmic institution within lineage and time: the Purana treats rulers as accountable within a recorded succession, where their reigns and lifespans become part of moral-historical memory.
No Vastu, temple-building, or ritual procedure is mentioned in this verse; its focus is genealogical prophecy about kings and their longevity.
