Matsya Purana — Yadu Lineage
षष्ठो ह्य् आडीबकाख्यस्तु सप्तमस्त्रैपुरस्तथा अन्धकाख्यो ऽष्टमस्तेषां नवमो वृत्रघातकः //
ṣaṣṭho hy āḍībakākhyastu saptamastraipurastathā andhakākhyo 'ṣṭamasteṣāṃ navamo vṛtraghātakaḥ //
Among them, the sixth is called ĀḌībaka; the seventh is Traipura; the eighth is named Andhaka; and the ninth is the slayer of Vṛtra (Vṛtra-ghātaka).
This verse is not about Pralaya; it is a technical name-list enumerating specific forms/attendants (or weapon-associated manifestations) used in ritual and iconographic contexts.
Indirectly, such enumerations support dharmic practice: kings and householders sponsor worship, consecrations, and protective rites where correct recitation of sanctioned name-lists is considered essential for efficacy and legitimacy.
The ritual significance is the precise identification of specific named forms (e.g., Traipura, Andhaka, Vṛtraghātaka) that can be invoked or placed in a deity’s protective retinue (āvaraṇa) during temple installation and related pūjā/nyāsa procedures.
