जातमात्रं च तस्यापि यावत्पुत्रशतं तथा च्यवनस्य तु शापेन विनाशमपयास्यति //

Even from the moment of his birth, and even if a hundred sons are born to him, he will nonetheless meet destruction—brought about by the curse of Cyavana.
This verse does not describe cosmic pralaya; it speaks of personal ruin (vināśa) caused by a sage’s curse within a dynastic narrative.
It underscores that lineage and progeny do not protect one from the results of adharma; a ruler or householder must uphold dharma and avoid actions that provoke a ṛṣi’s curse or moral downfall.
No Vāstu or temple-ritual rule is stated here; the focus is genealogical and ethical, emphasizing the power of śāpa (curse) in Purāṇic history.
