Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
तस्य पुत्रः पृथुर्नाम विश्वगश्चपृथोः सुतः इन्दुस्तस्य च पुत्रो ऽभूद् युवनाश्वस्ततो ऽभवत् //
tasya putraḥ pṛthurnāma viśvagaścapṛthoḥ sutaḥ industasya ca putro 'bhūd yuvanāśvastato 'bhavat //
His son was named Pṛthu, and Viśvaga was the son of Pṛthu. Indu was born as Viśvaga’s son, and from Indu was born Yuvanāśva.
This verse does not describe Pralaya; it preserves dynastic continuity by listing a succession of kings, emphasizing lineage transmission rather than cosmic dissolution.
Indirectly, it frames dharma through hereditary succession: the Matsya Purana often situates royal duty (rājadharma) within stable lineage, implying that governance and social order are sustained through legitimate descent.
No Vastu, temple-building, or ritual procedure is stated in this verse; it is strictly a genealogical notice used to anchor later narratives and dharmic discussions in a recognized royal line.
