Matsya Purana — Genealogy of Kaśyapa: Ādityas
इल्वलो नमुचिश्चैव श्वसृपश् चाजनस् तथा नरकः कालनाभश्च सरमाणस् तथैव च //
ilvalo namuciścaiva śvasṛpaś cājanas tathā narakaḥ kālanābhaśca saramāṇas tathaiva ca //
Ilvala and Namuci, and also Śvasṛpa and Ajana; Naraka and Kālanābha, and likewise Saramāṇa—these too are named among them.
This verse is not a Pralaya (dissolution) teaching; it functions as a genealogical/categorical naming of beings (often classed as Asuras/Daityas/Dānavas) within the Purāṇa’s early-world catalogues.
Directly, it does not prescribe rājadharma or gṛhastha-dharma; indirectly, such catalogues frame the Purāṇic moral universe by identifying forces opposed to dharma, against which kings are expected to protect society.
No Vāstu, temple-building, iconographic, or ritual procedure is stated in this verse; it is purely a name-list within a mythic-genealogical register.
