Matsya Purana — Yadu Lineage
प्रह्लादो निर्जितो युद्धे इन्द्रेणामृतमन्थने विरोचनस्तु प्राह्लादिर् नित्यम् इन्द्रवधोद्यतः //
prahlādo nirjito yuddhe indreṇāmṛtamanthane virocanastu prāhlādir nityam indravadhodyataḥ //
In the battle connected with the churning for nectar, Prahlāda was defeated by Indra; and Virocana, the son of Prahlāda, remained ever intent on slaying Indra.
This verse does not address Pralaya; it situates a Deva–Asura conflict within the Amṛta-manthana narrative, emphasizing rivalry and karmic enmity rather than cosmic dissolution.
Indirectly, it serves as a cautionary ethical motif: sustained vengeance (being “ever intent on killing”) perpetuates conflict across generations, contrasting with the Purāṇic ideal of restraint, righteous policy, and stability in governance.
No Vāstu, temple iconography, or ritual procedure is stated in this verse; the focus is historical-genealogical, tied to the Amṛta-manthana battle context.
