Matsya Purana — Genealogy of Kaśyapa: Ādityas
स्वर्भानोस्तु प्रभा कन्या शची चैव पुलोमजा उपदानवी मयस्यासीत् तथा मन्दोदरी कुहूः //
svarbhānostu prabhā kanyā śacī caiva pulomajā upadānavī mayasyāsīt tathā mandodarī kuhūḥ //
Svarbhānu’s daughter was Prabhā; and Śacī was the daughter of Puloman. Upadānavī became the wife of Maya; likewise there were Mandodarī and Kuhū.
This verse does not describe Pralaya; it preserves genealogical memory by listing notable women and marital connections among Dānava-related lineages.
Indirectly, it supports the Purāṇic ideal of preserving vaṁśa (lineage) records—important for kingship legitimacy, social order, and ancestral remembrance through correct naming and family history.
No ritual or Vāstu rule is stated, but the mention of Maya (a famed Dānava artisan/architect in Purāṇic tradition) is a genealogical reference that later traditions associate with extraordinary craftsmanship.
