Matsya Purana — Paurava Genealogy
चैद्योपरिचरो वीरो वसुर्नामान्तरिक्षगः चैद्योपरिचराज्जज्ञे गिरिका सप्त वै सुतान् //
caidyoparicaro vīro vasurnāmāntarikṣagaḥ caidyoparicarājjajñe girikā sapta vai sutān //
There was the heroic Vasu, renowned as Caidyoparicara, who moved through the sky. From Caidyoparicara, Girikā indeed bore seven sons.
This verse does not discuss Pralaya; it belongs to the dynastic (vaṁśa) narration, identifying King Vasu (Caidyoparicara) and stating that Girikā bore him seven sons.
Indirectly, it supports the Matsya Purana’s royal-ethics framework by grounding dharma in lineage and succession: a king’s household and progeny ensure continuity of governance and ritual obligations through the royal line.
No explicit Vastu Shastra, temple architecture, or ritual procedure is stated in this verse; its focus is purely genealogical (naming the king and noting the birth of seven sons).
