Matsya Purana — Code of Conduct and Vow-Procedure for Courtesans
ततः प्रभृति यो विप्रो रत्यर्थं गृहमागतः स मान्यः सूर्यवारे च स मन्तव्यो भवेत्तदा //
tataḥ prabhṛti yo vipro ratyarthaṃ gṛhamāgataḥ sa mānyaḥ sūryavāre ca sa mantavyo bhavettadā //
From that time onward, any Brahmin who comes to the house seeking sensual enjoyment is to be honored and treated with respect; and on Sunday as well, at that time, he is to be regarded as worthy of reverence.
This verse does not address pralaya or cosmology; it focuses on social-ethical conduct within household life, specifically how certain guests are to be treated.
It reinforces gṛhastha-dharma: honoring a visiting vipra as part of prescribed etiquette. The verse frames guest-honor (mānya, mantavya) as a normative duty, implying that social order and merit depend on regulated hospitality and respect.
No vastu/temple-architecture rule appears here; the ritual element is the weekday marker (sūryavāra), indicating that observances and conduct may be conditioned by calendrical/ritual time.
