Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
दैत्यैः प्राह यदि स्वामी वो भवामि ततस्त्वलम् नासुरैः प्रतिपन्नं तत् प्रतिपन्नं सुरैस्तथा //
daityaiḥ prāha yadi svāmī vo bhavāmi tatastvalam nāsuraiḥ pratipannaṃ tat pratipannaṃ suraistathā //
He said to the Daityas: “If I become your lord, then let that be enough. What has been agreed to by the Asuras has likewise been accepted by the Devas.”
This verse does not address Pralaya; it focuses on political acceptance and mutual ratification between Daityas/Asuras and the Devas.
It reflects a dharmic principle of governance: legitimacy arises from acknowledged consent and keeping to what has been mutually accepted—an ideal relevant to kingship, treaties, and social order.
No Vastu, temple-building, or ritual procedure is stated here; the verse is about authority and agreement between rival groups.
