Matsya Purana — Kailasa
पुलिकांश्च कुलत्थांश्च अङ्गलोक्यान्वरांश्च यान् कृत्वा द्विधा हिमवन्तं प्रविष्टा दक्षिणोदधिम् //
pulikāṃśca kulatthāṃśca aṅgalokyānvarāṃśca yān kṛtvā dvidhā himavantaṃ praviṣṭā dakṣiṇodadhim //
Having divided (the peoples/regions) such as the Pulikas and the Kulatthas, and also the folk of Aṅga and the Varas—splitting the Himavat in two—it then entered the Southern Ocean.
This verse is not about Pralaya; it belongs to the Purana’s geographic narration, describing how a major flow/course (implicitly a river-system or boundary line) traverses the Himalaya and reaches the Southern Ocean while delineating regions/peoples.
Indirectly, it supports rajadharma through knowledge of janapadas (regions and peoples): a king’s governance, taxation, protection, and pilgrimage patronage depend on understanding territorial divisions and routes described in Puranic geography.
No direct Vastu or ritual rule appears here; the practical takeaway is topographic orientation—Himalaya-to-southern-sea directionality—which later aids pilgrimage planning and temple network siting across regions.
