Matsya Purana — Manvantaras
गुरुवीतश्च मान्धाता अम्बरीषस्तथैव च युवनाश्वः पुरुकुत्सः स्वश्रवस्तु सदस्यवान् //
guruvītaśca māndhātā ambarīṣastathaiva ca yuvanāśvaḥ purukutsaḥ svaśravastu sadasyavān //
And (there were) Guruvīta, Māndhātā, and likewise Ambarīṣa; Yuvanāśva, Purukutsa, and Svaśravas—a king endowed with a worthy council of advisors.
This verse does not discuss Pralaya; it belongs to a genealogical passage listing notable kings of the Solar dynasty.
By describing Svaśravas as 'sadasyavān' (supported by an assembly/council), it implies an ideal of kingship where rulers govern with competent advisers rather than by isolated will—an ethical-political norm echoed across Purāṇic rajadharma.
No Vāstu, temple-building, or ritual procedure is stated in this verse; its focus is dynastic enumeration and a brief kingship attribute (having a council).
