Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
अनमित्रसुतो निघ्नो निघ्नस्यापि तु द्वौ सुतौ प्रसेनश्च महावीर्यः शक्तिसेनश्च ताव् उभौ //
anamitrasuto nighno nighnasyāpi tu dvau sutau prasenaśca mahāvīryaḥ śaktisenaśca tāv ubhau //
Anamitra’s son was Nighna. And Nighna, in turn, had two sons—Prasena, of great valor, and Śaktisena; these two were his sons.
This verse does not discuss Pralaya; it is a genealogical entry preserving royal succession—Anamitra → Nighna → (Prasena, Śaktisena).
Indirectly, it supports the Purāṇic ideal of orderly succession and continuity of kṣatriya lineages, which underpins the king’s duty to preserve social stability and dharma across generations.
No Vāstu, temple-building, or ritual procedure is stated here; the verse functions purely as a dynastic record within the Matsya Purana’s lineage tradition.
