Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
वासुकिस्तक्षकश्चैव कर्कोटकधनंजयौ एलामुखः कालियश्च महापद्मश्च वीर्यवान् //
vāsukistakṣakaścaiva karkoṭakadhanaṃjayau elāmukhaḥ kāliyaśca mahāpadmaśca vīryavān //
Vāsuki and Takṣaka as well; Karkoṭaka and Dhanaṃjaya; Elāmukha and Kāliya; and the mighty Mahāpadma—these are the powerful Nāgas (serpent-lords).
This verse does not describe Pralaya directly; it preserves a Puranic catalogue of Nāga lords, supporting the Matsya Purāṇa’s broader cosmological mapping of beings across realms.
Indirectly, it serves as authoritative tradition (smṛti-style remembrance): knowing sacred lineages and cosmic orders is presented in Purāṇas as part of a learned king’s or householder’s cultural-religious literacy.
No explicit Vāstu or ritual procedure appears here; however, Nāga names commonly inform temple/ritual invocations and protective iconography in later practice, where Nāgas are invoked for guardianship and auspiciousness.
