Matsya Purana — Prayaga Mahatmya Begins: Yudhishthira’s Remorse
भारते तु यदा वृत्ते प्राप्तराज्ये पृथासुते एतस्मिन्नन्तरे राजा कुन्तीपुत्रो युधिष्ठिरः //
bhārate tu yadā vṛtte prāptarājye pṛthāsute etasminnantare rājā kuntīputro yudhiṣṭhiraḥ //
When the events of the Bhārata had taken place and Pṛthā’s son had obtained the kingdom, in that interval King Yudhiṣṭhira—the son of Kuntī—ruled.
This verse does not discuss pralaya; it situates the narrative in the post-Bhārata period, marking Yudhiṣṭhira’s attainment of kingship.
By foregrounding Yudhiṣṭhira’s accession, it frames the ethical ideal of kingship (rājadharma) associated with him in Purāṇic-Itihāsa tradition—rule after conflict, restoration of order, and governance grounded in dharma.
No explicit Vāstu/temple-building or ritual procedure appears in this verse; it functions as a historical-genealogical transition into a royal narrative context.
