Matsya Purana — Paurava Genealogy: Bharata
*सूत उवाच पूरोः पुत्रो महातेजा राजा स जनमेजयः प्राचीत्वतः सुतस्तस्य यः प्राचीमकरोद्दिशम् //
*sūta uvāca pūroḥ putro mahātejā rājā sa janamejayaḥ prācītvataḥ sutastasya yaḥ prācīmakaroddiśam //
Sūta said: From Puru was born the mighty, radiant king Janamejaya. His son was Prācītvata, who made the eastern quarter renowned—expanding his rule toward the East.
This verse does not discuss Pralaya; it is a genealogical notice establishing succession in the Puru dynasty and a king associated with expansion toward the East.
Indirectly, it reflects the Purāṇic ideal of kingship through lineage and territorial governance—naming rulers whose fame is tied to protecting and organizing regions (here, the eastern quarter).
No explicit Vāstu or ritual rule appears here; the only technical note is directional (prācī, ‘east’), a key concept later used in Vāstu and ritual orientation, but not elaborated in this verse.
