Matsya Purana — Yadu Lineage
*मुनय ऊचुः कथं देवासुरकृते व्यापारं प्राप्तवान्स्वतः देवासुरं यथा वृत्तं तन्नः प्रब्रूहि पृच्छताम् //
*munaya ūcuḥ kathaṃ devāsurakṛte vyāpāraṃ prāptavānsvataḥ devāsuraṃ yathā vṛttaṃ tannaḥ prabrūhi pṛcchatām //
The sages said: “How did you, of your own accord, come to undertake action in the affair of the Devas and the Asuras? Tell us, as we ask, exactly how the conflict between the Devas and the Asuras took place.”}]}
This verse does not describe pralaya directly; it frames a narrative inquiry about divine intervention in deva–asura affairs, a common Purāṇic motif for explaining how cosmic order (ṛta/dharma) is maintained.
By emphasizing a requested, orderly account of conflict and intervention, it reflects the Purāṇic ethic that power should act with purpose and accountability—paralleling a king’s duty to intervene against disorder and explain actions in terms of dharma.
No Vāstu or ritual procedure is specified in this verse; it functions as a transition into a deva–asura episode, which elsewhere may ground later ritual or iconographic teachings by establishing divine authority and precedent.
