Matsya Purana — Śiva–Pārvatī Quarrel and Pārvatī’s Resolve for Austerity to Attain Gaurī-hood
यथा न काचित् प्रविशेद् योषिदत्र हरान्तिकम् दृष्ट्वा परांस्त्रियं चात्र वदेथा मम पुत्रक //
yathā na kācit praviśed yoṣidatra harāntikam dṛṣṭvā parāṃstriyaṃ cātra vadethā mama putraka //
See that no woman enters here into the private proximity of another man. And if you happen to see another man’s wife here, speak up at once: “She is mine, my son!”
Nothing directly—this verse is ethical instruction (nīti/ācāra) focused on household boundaries and social propriety, not cosmology or pralaya.
It frames a duty of vigilance and boundary-keeping: a householder (and by extension a ruler responsible for public order) should prevent improper access and situations that could lead to scandal, coercion, or breach of marital/social norms.
There is no explicit Vāstu or ritual rule, but it implies controlled access to private quarters—an idea that can align with household/inner-space management rather than temple architecture.
