Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
सत्यवान्युयुधानस्तु शिनेर्नप्ता प्रतापवान् असङ्गो युयुधानस्य द्युम्निस्तस्यात्मजो ऽभवत् //
satyavānyuyudhānastu śinernaptā pratāpavān asaṅgo yuyudhānasya dyumnistasyātmajo 'bhavat //
Now, Satyavān—namely Yuyudhāna—was the valiant grandson of Śini. From Yuyudhāna was born Asaṅga, and Dyumni was born as Asaṅga’s son.
Nothing directly—this verse is genealogical, preserving dynastic succession rather than describing pralaya (cosmic dissolution).
Indirectly, it supports the Purāṇic ideal of continuity through righteous lineage—kingship and household life are framed as responsibilities carried forward through generations.
None is stated here; the verse is focused on lineage (vaṃśa) and does not discuss Vāstu, temple rules, or ritual procedure.
