Matsya Purana — Genealogy of the Śūra–Vasudeva
ऐक्ष्वाक्यलभतापत्यम् अनाधृष्टेर्यशस्विनी निधूतसत्त्वं शत्रुघ्नं श्राद्धस्तस्मादजायत //
aikṣvākyalabhatāpatyam anādhṛṣṭeryaśasvinī nidhūtasattvaṃ śatrughnaṃ śrāddhastasmādajāyata //
From Anādhṛṣṭi, the illustrious Yaśasvinī bore a son in the Ikṣvāku lineage; and from him was born Śrāddha—also known as Śatrughna—pure in nature and a destroyer of foes.
This verse does not address Pralaya; it is a dynastic (vaṃśa) record describing succession and birth within the Ikṣvāku/Solar lineage.
Indirectly, it supports the Purāṇic ideal of righteous succession: kingship is framed through legitimate lineage and the rise of heirs described as 'pure in nature' and 'slayers of foes,' qualities associated with royal protection (rakṣaṇa) and order.
No Vāstu, temple architecture, or ritual procedure is taught in this verse; it functions purely as genealogical documentation within the Matsya Purana’s royal chronicles.
