Matsya Purana — Inquiry into Taraka’s Slaying and the Prelude to Guha
वज्राङ्गो नाम दैत्येन्द्रः कस्य वंशोद्भवः पुरा यस्याभूत्तारकः पुत्रः सुरप्रमथनो बली //
vajrāṅgo nāma daityendraḥ kasya vaṃśodbhavaḥ purā yasyābhūttārakaḥ putraḥ surapramathano balī //
“There was a lord of the Daityas named Vajrāṅga. From which lineage did he arise in former times—he whose son was Tāraka, the mighty one who crushed the hosts of the gods?”
This verse does not address Pralaya; it focuses on genealogical inquiry—identifying the lineage of the Daitya-king Vajrāṅga and noting his son Tāraka’s hostility toward the gods.
Indirectly, it supports the Purāṇic use of genealogy as moral-political instruction: rulers are remembered by lineage and deeds, and hostile power (like Tāraka’s) becomes a cautionary example of strength used against dharma-aligned order.
No Vāstu, temple-building, or ritual procedure is mentioned in this verse; it is purely dynastic (vaṃśa) and narrative in scope.
