Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
बृहस्पतिगृहे सर्वे जातकर्मोत्सवे तदा अपृच्छंस्ते सुरास्तारां केन जातः कुमारकः //
bṛhaspatigṛhe sarve jātakarmotsave tadā apṛcchaṃste surāstārāṃ kena jātaḥ kumārakaḥ //
Then, at Bṛhaspati’s house, during the child’s birth-rite celebration (jātakarma), all the gods asked Tārā: “By whom was this boy begotten?”
This verse does not address pralaya; it focuses on a social-ritual moment (jātakarma) and a genealogical question about a child’s paternity.
It highlights the importance of saṃskāras—especially jātakarma—as a householder duty, and reflects how lineage and rightful parentage were treated as ethically and socially significant in Purāṇic culture.
Ritually, it explicitly situates the scene in the jātakarma celebration—an early-life saṃskāra marking a child’s formal welcome and blessing—rather than any Vāstu or temple-building rule.
