Matsya Purana — Solar Dynasty Prelude: Vivasvān–Saṃjñā–Chāyā
विवस्वानथ तज्ज्ञात्वा संज्ञायाः कर्मचेष्टितम् त्वष्टुः समीपमगमद् आचचक्षे च रोषवान् //
vivasvānatha tajjñātvā saṃjñāyāḥ karmaceṣṭitam tvaṣṭuḥ samīpamagamad ācacakṣe ca roṣavān //
Then Vivasvān (the Sun), having understood Saṃjñā’s conduct and actions, went to Tvaṣṭṛ’s presence and, filled with anger, reported the matter to him.
This verse does not address Pralaya; it belongs to a genealogical/narrative thread about Vivasvān, Saṃjñā, and Tvaṣṭṛ, focusing on interpersonal and dynastic developments rather than cosmic dissolution.
Indirectly, it reflects the Purāṇic emphasis on accountability in household life: when disorder arises in conduct (karma-ceṣṭitam), the aggrieved party seeks adjudication from an elder/guardian figure (here, Tvaṣṭṛ), mirroring how disputes are to be addressed through proper authority rather than unchecked anger.
No Vāstu or temple-building rule is stated in this verse; the only technical-cultural note is the presence of Tvaṣṭṛ, the divine artisan, who elsewhere is associated with craftsmanship and sacred making, but here functions as Saṃjñā’s paternal authority.
