Matsya Purana — Bhīma-Dvādaśī
तस्यां कदाचिदासीनः सभायाममितद्युतिः भार्याभिर्वृष्णिभिश्चैव भूभृद्भिर् भूरिदक्षिणैः //
tasyāṃ kadācidāsīnaḥ sabhāyāmamitadyutiḥ bhāryābhirvṛṣṇibhiścaiva bhūbhṛdbhir bhūridakṣiṇaiḥ //
Once, while seated in the royal assembly in that city, the Lord of boundless splendor sat surrounded by his queens, by the Vṛṣṇi heroes, and by many kings renowned for their abundant gifts and generosity.
This verse does not discuss pralaya; it is a courtly narrative snapshot emphasizing royal splendor and the presence of generous rulers.
By highlighting “bhūridakṣiṇaiḥ” (those who give abundant gifts), the verse aligns kingship with dāna (charitable giving) and public generosity as a hallmark of righteous rule.
While no Vāstu rule is stated, the mention of “sabhā” (assembly hall) points to the institutional space of governance; later Vāstu contexts treat sabhā as a key royal/public structure, but this verse itself is descriptive rather than prescriptive.
