Matsya Purana — Yayāti in Amarāvatī-like Splendor: Devayānī Installed
ऋतुकाले तु सम्प्राप्ते देवयानी वराङ्गना लेभे गर्भं प्रथमतः कुमारश्च व्यजायत //
ṛtukāle tu samprāpte devayānī varāṅganā lebhe garbhaṃ prathamataḥ kumāraśca vyajāyata //
When the season of fertility arrived, Devayānī, that noble and beautiful lady, first conceived; and in due course a son was born.
This verse does not discuss pralaya; it focuses on human lineage—Devayānī’s conception and the birth of a son—supporting the Purāṇa’s dynastic continuity themes.
It reflects the householder ideal of progeny and lineage-continuation (prajā), a central Purāṇic concern tied to dharma, inheritance, and the stability of royal and familial succession.
No Vāstu/temple-building rule is stated here; the only implicit ritual frame is ṛtukāla—conjugal timing regarded in Dharma traditions as appropriate for conception.
