Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
शुचिविद्यः शतायुश्च सर्वे दिव्यबलौजसः आयुषो नहुषः पुत्रौ वृद्धशर्मा तथैव च //
śucividyaḥ śatāyuśca sarve divyabalaujasaḥ āyuṣo nahuṣaḥ putrau vṛddhaśarmā tathaiva ca //
Śucividya and Śatāyu—indeed all of them endowed with divine strength and vigor—were the sons of Āyuṣa and Nahuṣa; and likewise there was Vṛddhaśarmā.
This verse does not describe Pralaya; it functions as a genealogical record, listing descendants in the Āyuṣa–Nahuṣa line and emphasizing their exceptional (divya) vigor.
Indirectly, it supports the Matsya Purāṇa’s royal-ethical framework by preserving lineage memory: dynastic catalogues legitimize kingship and imply ideals of longevity, strength, and dharma that rulers are expected to embody.
No Vāstu, temple-building, or ritual procedure is mentioned; the verse is strictly genealogical, useful for tracing Puranic dynasties rather than Matsya Purana Vastu Shastra tips.
