Matsya Purana — Inquiry into Taraka’s Slaying and the Prelude to Guha
दितेः सकाशाल्लोकास्तु हिरण्यकशिपादयः दानवाश्च दनोः पुत्रा गावश्च सुरभीसुताः //
diteḥ sakāśāllokāstu hiraṇyakaśipādayaḥ dānavāśca danoḥ putrā gāvaśca surabhīsutāḥ //
From Diti arose lineages such as Hiraṇyakaśipu and others; from Danu were born the Dānavas; and from Surabhī came forth the cattle, the cows.
It does not describe Pralaya directly; it catalogs creation through lineage—how specific classes of beings (Daityas/Dānavas) and cattle are said to originate from Diti, Danu, and Surabhī.
Indirectly, it grounds dharma in cosmic order: knowing genealogies and the sanctity of Surabhī-born cattle supports household and royal ethics such as go-rakṣaṇa (protection of cattle) and proper social-ritual conduct.
No Vāstu or temple rule is stated, but the mention of Surabhī-born cows links to ritual economy—milk, ghee, and other cow-products central to yajña and consecration rites in Purāṇic practice.
