Matsya Purana — Dynastic Genealogies: Paurava–Anu Lines
तामुवाच ततः सो ऽथ यत्ते परिहृतं शुभे विनापानं कुमारं तु जनयिष्यसि पूर्वजम् //
tāmuvāca tataḥ so 'tha yatte parihṛtaṃ śubhe vināpānaṃ kumāraṃ tu janayiṣyasi pūrvajam //
Then he spoke to her: “Auspicious one, that which was withheld from you—you shall give birth to a son, Vināpāna, an elder-born, born first.”
This verse does not describe Pralaya; it focuses on a prophecy of birth and lineage continuity, a common Purāṇic theme used to preserve dynastic history.
It reflects the Purāṇic concern with legitimate succession and lineage: for kings, ensuring rightful heirs; for householders, the dharmic continuity of family through progeny.
No Vāstu/temple-architecture or ritual procedure is stated in this verse; its significance is genealogical and prophetic rather than architectural.
