Matsya Purana — Dynastic Genealogies: Paurava–Anu Lines
प्रचेतसः पुत्रशतं राजानः सर्व एव ते म्लेच्छराष्ट्राधिपाः सर्वे उदीचीं दिशम् आश्रिताः //
pracetasaḥ putraśataṃ rājānaḥ sarva eva te mleccharāṣṭrādhipāḥ sarve udīcīṃ diśam āśritāḥ //
All those kings—the one hundred sons of Pracetasa—became rulers over Mleccha kingdoms, and all of them were established in the northern direction.
This verse is not about Pralaya; it is a genealogical-geographical note describing how Pracetas’ hundred sons became rulers of northern Mleccha realms.
Indirectly, it frames kingship as territorial governance: rulers are identified by the realms they administer, emphasizing the Purāṇic concern with legitimate lineages and the ordering of regions under royal authority.
No Vāstu or ritual procedure is stated in this verse; its significance lies in mapping dynasties to regions (especially the northern quarter), which can contextualize later references to regional customs and polities.
