Matsya Purana — Yadu Lineage
बुद्ध्वा तदन्तरं सो ऽपि दैत्यानामिन्द्रनोदितः काव्यस्य रूपमास्थाय असुरान् समुपाह्वयत् //
buddhvā tadantaraṃ so 'pi daityānāmindranoditaḥ kāvyasya rūpamāsthāya asurān samupāhvayat //
Having understood that opportune interval, he too—urged on by Indra—assumed the form of Kāvya (Śukrācārya) and summoned the Asuras.
This verse does not address Pralaya; it focuses on tactical maneuvering in a Deva–Asura conflict, highlighting disguise and counsel rather than cosmic dissolution.
Indirectly, it reflects the Purāṇic theme of nīti (statecraft): recognizing the right moment (antara) and acting decisively—though the verse itself depicts a deceptive tactic rather than an explicit dharma teaching.
No Vāstu, temple-building, or ritual procedure is stated here; the content is narrative and political-strategic (assuming a form and summoning opponents).
