Matsya Purana — Yadu Lineage
श्रुत्वा तथा ब्रुवाणं तं संभ्रान्तास्ते तदाभवन् प्रेक्षन्तस् ताव् उभौ तत्र स्थितासीनौ सुविस्मिताः //
śrutvā tathā bruvāṇaṃ taṃ saṃbhrāntāste tadābhavan prekṣantas tāv ubhau tatra sthitāsīnau suvismitāḥ //
Hearing him speak in that manner, they became agitated at that time; and, gazing there upon those two—one standing and one seated—they remained utterly astonished.
It signals the solemn, extraordinary tone of the Pralaya-related discourse: the listeners’ agitation and amazement indicate that the speech concerns events beyond ordinary experience, consistent with the Matsya Purana’s flood/pre-dissolution narrative atmosphere.
Indirectly, it models attentive reception of authoritative teaching: when divine or dharmic instruction is given (as in the Manu-centered frame), the proper response is focused observation and seriousness—qualities essential for a king or householder who must act on guidance responsibly.
No explicit Vāstu or ritual procedure is stated in this verse; its function is narrative—marking the awe and heightened attention that typically precede important instructions (which, elsewhere in the Matsya Purana, may include ritual and technical teachings).
