Matsya Purana — Yadu Lineage
सम्प्रमूढास् ततः सर्वे न प्राबुध्यन्त किंचन अब्रवीत् सम्प्रमूढेषु काव्यस्तानसुरांस्तदा //
sampramūḍhās tataḥ sarve na prābudhyanta kiṃcana abravīt sampramūḍheṣu kāvyastānasurāṃstadā //
Then all of them became utterly bewildered and could understand nothing at all. At that moment, Kāvya (Śukra) spoke to those deluded Asuras.
Nothing directly about Pralaya is stated here; the verse focuses on moha (bewilderment) in an Asura episode, showing how confusion precedes a decisive intervention by a teacher (Śukra/Kāvya).
It implies a core dharmic lesson: when judgment is clouded, one should seek competent counsel (guru/minister) rather than act blindly—an indirect guideline relevant to royal policy and household decision-making.
No Vāstu, temple-building, or ritual procedure is mentioned in this specific verse; it is a narrative transition introducing Śukra’s instruction to the Asuras.
