Matsya Purana — Yayāti’s Rule
पूरोस्तु पौरवो वंशो यत्र जातो ऽसि पार्थिव इदं वर्षसहस्रात्तु राज्यं कुरुकुलागतम् //
pūrostu pauravo vaṃśo yatra jāto 'si pārthiva idaṃ varṣasahasrāttu rājyaṃ kurukulāgatam //
From Pūru arises the Paurava lineage, in which you were born, O king. This sovereignty has come down in the Kuru family for a thousand years.
This verse does not discuss Pralaya; it focuses on dynastic continuity—how royal authority is inherited through the Paurava–Kuru line.
By grounding kingship in an inherited lineage, it implies the king’s dharma includes preserving the stability, customs, and responsibility of a long-established royal succession.
No direct Vāstu or ritual procedure is stated; the verse is primarily genealogical, serving as a historical-legal validation of sovereignty.
