Matsya Purana — Yadu Lineage
बृहस्पतिर् उवाचैनान् असम्भ्रान्तस्तपोधनः काव्यो वो ऽहं गुरुर्दैत्या मद्रूपो ऽयं बृहस्पतिः //
bṛhaspatir uvācainān asambhrāntastapodhanaḥ kāvyo vo 'haṃ gururdaityā madrūpo 'yaṃ bṛhaspatiḥ //
Bṛhaspati, the serene ascetic rich in austerity, addressed them: “O Daityas, I am Kāvya (Śukra), your preceptor. This Bṛhaspati here bears my very form.”
Nothing directly—this verse belongs to a narrative episode about counsel and deception among Devas/Daityas, not the Pralaya cosmology.
It highlights the political-ethical theme that discernment (viveka) is essential: rulers must verify advisors and appearances, since even “guru” authority can be mimicked to mislead a polity.
No Vāstu or ritual procedure is stated in this verse; its focus is narrative identity-claim and strategic speech.
