Matsya Purana — Genealogy of Kaśyapa: Ādityas
धृतराष्ट्रस् तथा सूर्यश् चन्द्रश्चन्द्रांशुतापनः निकुम्भनाभो गुर्वक्षः कुक्षिभीमो विभीषणः //
dhṛtarāṣṭras tathā sūryaś candraścandrāṃśutāpanaḥ nikumbhanābho gurvakṣaḥ kukṣibhīmo vibhīṣaṇaḥ //
Also (are named) Dhṛtarāṣṭra; Sūrya (the Sun); Candra (the Moon); Candrāṃśu-tāpana, “the heater by moon-rays”; Nikumbha-nābha, “he whose navel is like Nikumbha”; Gurv-akṣa, “heavy-eyed”; Kukṣi-bhīma, “terrible in the belly”; and Vibhīṣaṇa.
This verse does not describe Pralaya directly; it functions as a catalogue of names/epithets, a common Purāṇic method for preserving traditional memory and lineages rather than narrating cosmic dissolution.
Indirectly: Purāṇic name-lists anchor dharma through lineage and exemplars—figures like Sūrya and Candra underpin royal legitimacy (solar/lunar lines), while Vibhīṣaṇa is remembered as a model of righteous allegiance and ethical choice.
No Vāstu or ritual procedure is taught in this specific śloka; it is primarily onomastic (names). Its practical value is contextual—helping place later ritual, dynasty, and temple-donation narratives within recognized Purāṇic personages.
