Matsya Purana — The Legend of Acchodā: Pitṛloka
कन्या भूत्वा च लोकान्स्वान् पुनराप्स्यसि दुर्लभान् पराशरस्य वीर्येण पुत्रमेकमवाप्स्यसि //
kanyā bhūtvā ca lokānsvān punarāpsyasi durlabhān parāśarasya vīryeṇa putramekamavāpsyasi //
Having become a maiden, you shall regain again your own worlds that are hard to attain; and by the potency of Parāśara you shall obtain a single son.
This verse does not describe Pralaya; it focuses on personal destiny—restoration of a maiden-state and the begetting of a son through the sage Parāśara.
Indirectly, it reflects the Purāṇic emphasis on lineage and righteous progeny: household life and social order are sustained through dharmic continuity of descendants, here foretold as a single son.
No Vāstu, temple-building, or ritual procedure is specified in this verse; its technical focus is on destiny, purity/maidenhood, and lineage through Parāśara.
