Matsya Purana — Paurava Genealogy
सोमकस्य सुतो जन्तुर् हते तस्मिञ्छतं बभौ पुत्राणामजमीढस्य सोमकस्य महात्मनः //
somakasya suto jantur hate tasmiñchataṃ babhau putrāṇāmajamīḍhasya somakasya mahātmanaḥ //
When Jantu, the son of Somaka, was slain, that great-souled Somaka—of the lineage of Ajāmīḍha—came to have a hundred sons.
This verse does not address pralaya; it belongs to a genealogical narration focused on royal succession and progeny in Somaka’s line.
Indirectly, it reflects the Purāṇic concern with continuity of lineage (putra-santāna) and royal succession—central social aims for kings and householders in dharma-based society.
No Vāstu, temple-building, or ritual procedure is stated in this verse; it is a lineage note about Somaka’s progeny after Jantu’s death.
