Matsya Purana — Solar Dynasty Prelude: Vivasvān–Saṃjñā–Chāyā
वव्रे स लोकपालत्वं पितृलोके नृपालयम् धर्माधर्मात्मकस्यापि जगतस्तु परीक्षणम् //
vavre sa lokapālatvaṃ pitṛloke nṛpālayam dharmādharmātmakasyāpi jagatastu parīkṣaṇam //
He chose the office of a world-guardian (Lokapāla), and kingship in the realm of the Fathers (Pitṛloka), along with the charge of examining the world—though it is of the nature of both dharma and adharma.
This verse is not describing pralaya directly; it emphasizes cosmic administration—appointing guardianship and the moral “testing” or discernment of the world’s dharma–adharma mixture, which is relevant to maintaining order across cosmic cycles.
It frames rulership as a moral office: a king (nṛpāla) must protect people while actively discerning and regulating dharma and adharma in society—governance is presented as ethical supervision, not merely power.
No vāstu/temple-construction rule is stated in this verse; the ritual-cosmological point is Pitṛloka’s governance and the duty of “parīkṣaṇa” (discernment), which aligns with broader Purāṇic ritual ethics rather than architecture.
