Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
देवकश्चोग्रसेनश्च देवगर्भसमाव् उभौ देवकस्य सुता वीरा जज्ञिरे त्रिदशोपमाः //
devakaścograsenaśca devagarbhasamāv ubhau devakasya sutā vīrā jajñire tridaśopamāḥ //
Devaka and Ugrasena—both born of Devagarbhā—are named. And to Devaka were born heroic sons, like the gods themselves.
Nothing directly—this verse is genealogical, naming Devaka and Ugrasena and praising Devaka’s godlike offspring, not describing pralaya or cosmology.
Indirectly, it supports the Purāṇic ideal that royal families preserve dharma through worthy progeny and legitimate lineage—an ethical emphasis on responsibility, succession, and continuity in household and kingship.
No explicit vastu/ritual rule appears here; the verse functions as a lineage record rather than a temple-building or sacrificial instruction.
