Matsya Purana — Division of Bhārata-varṣa
गान्धारा यवनाश्चैव सिन्धुसौवीरमद्रकाः शका द्रुह्याः पुलिन्दाश्च पारदाहारमूर्तिकाः //
gāndhārā yavanāścaiva sindhusauvīramadrakāḥ śakā druhyāḥ pulindāśca pāradāhāramūrtikāḥ //
Also (there are) the Gāndhāras and the Yavanas; the Sindhus, the Sauvīras, and the Madrakas; the Śakas, the Druhyas, and the Pulindas; and likewise the Pāradas, the Hāras, and the Mūrtikas.
Nothing directly—this verse is a geographic/ethnographic catalogue, naming peoples and regions rather than describing pralaya, cosmogenesis, or dissolution.
Indirectly, it supports rajadharma by mapping the known world: a king’s diplomacy, frontier policy, and protection of trade routes depend on knowing neighboring janapadas such as the Gandharas, Yavanas, and Śakas.
No explicit Vāstu or ritual rule appears here; the verse functions as a regional listing that can serve as contextual background for where rites, temples, and royal patronage might be situated across different lands.
