Matsya Purana — Solar Dynasty Prelude: Vivasvān–Saṃjñā–Chāyā
पुरतः संस्थितां दृष्ट्वा संज्ञा तां प्रत्यभाषत छाये तं भज भर्तारम् अस्मदीयं वरानने //
purataḥ saṃsthitāṃ dṛṣṭvā saṃjñā tāṃ pratyabhāṣata chāye taṃ bhaja bhartāram asmadīyaṃ varānane //
Seeing her standing before her, Saṃjñā spoke to her: “O Chāyā, O fair-faced one—go and attend upon that husband of ours.”
This verse does not address Pralaya directly; it belongs to an early mythic-genealogical narrative emphasizing domestic order and lineage context rather than cosmic dissolution.
It reflects gṛhastha-dharma in narrative form: maintaining the household order and marital role (service/companionship to the husband) is presented as a stabilizing duty that supports lineage and social continuity.
No Vāstu, temple-building, or ritual procedure is specified in this verse; its significance is genealogical and ethical (household conduct) rather than architectural.
