Matsya Purana — Intermediate Dissolution
यद्भवद्भिः पुरा पृष्टः सृष्ट्यादिकमहं द्विजाः तद् एवैकार्णवे तस्मिन् मनुः पप्रच्छ केशवम् //
yadbhavadbhiḥ purā pṛṣṭaḥ sṛṣṭyādikamahaṃ dvijāḥ tad evaikārṇave tasmin manuḥ papraccha keśavam //
Ó sábios duas-vezes-nascidos, o mesmo tema sobre a criação e assuntos correlatos que outrora me perguntastes—sobre esse mesmo assunto, naquele tempo do único oceano cósmico, Manu interrogou Keśava (Viṣṇu).
It frames the teaching as arising in the ekārṇava—an all-engulfing ocean condition associated with pralaya—where Manu asks Viṣṇu about creation and allied cosmological topics.
Indirectly: it establishes Manu (the archetypal lawgiver and ruler) as receiving foundational cosmological knowledge from Viṣṇu, which underpins later dharma-guidance for governance and right living.
None explicitly in this verse; it is a narrative bridge introducing a cosmological inquiry rather than Vāstu or ritual procedure.
