Matsya Purana — Division of Bhārata-varṣa
स्तोशलाः कोसलाश्चैव त्रैपुरा वैदिशास्तथा तुमुरास् तुम्बराश्चैव पद्गमा नैषधैः सह //
stośalāḥ kosalāścaiva traipurā vaidiśāstathā tumurās tumbarāścaiva padgamā naiṣadhaiḥ saha //
Also (are mentioned) the Stośalās and the Kosalas; likewise the Traipuras and the Vaidiśas; the Tumurās and the Tumbarās as well, and the Padgamās—together with the Naiṣadhas.
Nothing directly—this verse is a geographic/ethnographic catalog naming janapadas (peoples and regions), not a Pralaya description.
Indirectly: by listing recognized peoples and regions, it supports the Purana’s broader political-geographic worldview that kings must understand for governance, alliances, taxation, and protection of territories.
No explicit Vastu or ritual rule appears here; the verse functions as a toponymic/ethnonymic enumeration rather than prescribing temple architecture or rites.
