Matsya Purana — The Greatness and Procedure of the Aṅgāra
*ईश्वर उवाच अथ तद्वचनं श्रुत्वा भार्गवस्य महात्मनः प्रह्रादनन्दनो वीरः पुनः पप्रच्छ विस्मितः //
*īśvara uvāca atha tadvacanaṃ śrutvā bhārgavasya mahātmanaḥ prahrādanandano vīraḥ punaḥ papraccha vismitaḥ //
The Lord said: Having heard the words of the great-souled Bhārgava, the heroic son of Prahrāda, astonished, questioned him again.
This verse does not describe pralaya directly; it highlights the Purāṇic method of transmitting knowledge—after hearing a teaching, the listener (Prahrāda’s son) asks further questions to clarify doctrine.
Indirectly, it models dharmic conduct: attentive listening to a qualified teacher (Bhārgava) followed by respectful inquiry—an essential discipline for rulers and householders when learning dharma and governance.
No explicit Vāstu or ritual rule appears in this line; it functions as a narrative transition into further instruction, which in the Matsya Purāṇa often precedes technical teachings (including ritual and śāstric topics).
