Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
एवं पुरूरवाः पुंसोर् अभवद् वंशवर्धनः इक्ष्वाकुर् अर्कवंशस्य तथैवोक्तस्तपोधनाः //
evaṃ purūravāḥ puṃsor abhavad vaṃśavardhanaḥ ikṣvākur arkavaṃśasya tathaivoktastapodhanāḥ //
Thus, from that man (the progenitor), Purūravas became an increaser of the lineage; and Ikṣvāku—of the Solar (Arka/Sūrya) dynasty—has likewise been declared, O wealth of austerity.
This verse does not describe Pralaya; it focuses on royal genealogy, naming Purūravas and Ikṣvāku as key lineage-increasers, especially for the Solar dynasty.
By praising figures as “vaṃśavardhana” (upholders and increasers of the line), it implies the dharmic ideal that rulers preserve social order and continuity through righteous governance and legitimate succession.
No Vāstu/temple-building or ritual procedure is stated here; the verse is a genealogical marker within the Matsya Purana’s dynastic narration.
