Matsya Purana — Śukra Warns Vṛṣaparvan: The Ripening of Adharma and Devayānī’s Demand for Śar...
*शौनक उवाच एवमुक्तो द्विजश्रेष्ठो दुहित्रा सुमहायशाः प्रविवेश पुरं हृष्टः पूजितः सर्वदानवैः //
*śaunaka uvāca evamukto dvijaśreṣṭho duhitrā sumahāyaśāḥ praviveśa puraṃ hṛṣṭaḥ pūjitaḥ sarvadānavaiḥ //
Śaunaka said: Thus addressed, the foremost of the twice-born sages, of very great renown, entered the city with his daughter, delighted, and was honored by all the Dānavas.
This verse does not discuss Pralaya directly; it is a narrative transition describing a revered sage entering a city with his daughter and being honored by the Dānavas.
It highlights the dharmic ideal of honoring worthy guests (atithi-satkāra): even powerful groups like the Dānavas are depicted as offering respectful reception to a renowned dvija, reflecting a widely upheld social-ethical norm.
No specific Vāstu or ritual procedure is stated; the mention of entering a “pura” (city) functions as scene-setting rather than prescribing temple or town-planning rules.
