Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
देववानुपदेवश्च सुदेवो देवरक्षितः तेषां स्वसारः सप्तासन् वसुदेवाय ता ददौ //
devavānupadevaśca sudevo devarakṣitaḥ teṣāṃ svasāraḥ saptāsan vasudevāya tā dadau //
Devavān, Upadeva, Sudeva, and Devarakṣita—these were the sons. They had seven sisters; those seven were given in marriage to Vasudeva.
This verse does not discuss Pralaya; it records genealogical names and a marriage-alliance detail within a dynastic narrative.
It reflects the Purāṇic social-political practice of forming alliances through marriage, a householder (gṛhastha) institution and a royal strategy for stabilizing lineage and succession.
No Vāstu, temple-building, or ritual procedure is stated in this verse; its focus is strictly genealogical and matrimonial.
