Matsya Purana — Dynastic Genealogies: Paurava–Anu Lines
तस्य सा तद्वचो देवी सर्वं कृतवती तदा तस्य सापानम् आसाद्य देवी परिहरत्तदा //
tasya sā tadvaco devī sarvaṃ kṛtavatī tadā tasya sāpānam āsādya devī pariharattadā //
Hearing his words, the Goddess did everything accordingly. Then, when the occasion of his curse arose, she warded it off at that very time.
This verse does not discuss Pralaya; it illustrates a common Puranic motif where a divine being neutralizes the effects of a curse through timely intervention and adherence to instruction.
It emphasizes the dharmic principle of following rightful counsel and acting promptly—qualities expected of rulers and householders to prevent misfortune and maintain social and ritual order.
No explicit Vastu or temple-building rule is stated, but the idea of averting inauspicious outcomes aligns with ritual remedies (śānti) that the Matsya Purana often associates with maintaining auspiciousness.
