Matsya Purana — Ila–Sudyumna Episode and the Expansion of the Ikṣvāku
दीर्घबाहुरजाज्जातश् चाजपालस्ततो नृपः तस्माद्दशरथो जातस् तस्य पुत्रचतुष्टयम् //
dīrghabāhurajājjātaś cājapālastato nṛpaḥ tasmāddaśaratho jātas tasya putracatuṣṭayam //
From Aja was born Dīrghabāhu; and then the king Ajapāla. From him was born Daśaratha, who had a set of four sons.
This verse does not discuss Pralaya; it is a dynastic notice listing successive kings culminating in Daśaratha and his four sons.
By preserving succession and lineage, the verse supports the Purāṇic ideal of rājad-harma: stable inheritance, legitimate progeny, and continuity of governance through an established royal line.
No Vāstu, temple-building, or ritual procedure is stated here; the focus is purely genealogical, serving as narrative scaffolding for later dharma and tradition.
