Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
तस्य पुत्रास् त्रयो जाता दृढाश्वो दण्ड एव च कपिलाश्वश्च विख्यातो धौन्धुमारिः प्रतापवान् //
tasya putrās trayo jātā dṛḍhāśvo daṇḍa eva ca kapilāśvaśca vikhyāto dhaundhumāriḥ pratāpavān //
He had three sons: Dṛḍhāśva, Daṇḍa, and the renowned Kapilāśva—known as Dhaundhumāri—mighty and valorous.
Nothing directly—this verse is genealogical, listing three sons and highlighting Kapilāśva’s fame as Dhaundhumāri.
Indirectly: by preserving lineage records and praising pratāpa (royal valor), it reflects the Purāṇic ideal of kingship—protection, strength, and fame earned through righteous rule.
None is stated; the verse focuses on lineage and a celebrated epithet rather than Vastu Shastra, temple rules, or ritual procedure.
