Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
तथैवौण्ड्राश्च पौण्ड्राश्च वामचूडाः सकेरलाः क्षोभितास्तेन दैत्येन सदेवाश्चाप्सरोगणाः //
tathaivauṇḍrāśca pauṇḍrāśca vāmacūḍāḥ sakeralāḥ kṣobhitāstena daityena sadevāścāpsarogaṇāḥ //
Likewise, the Oṇḍras and the Pauṇḍras, the Vāmacūḍas and the Keralas—along with the gods and the hosts of Apsarās—were all thrown into agitation by that Daitya.
This verse does not describe Pralaya; it depicts worldly upheaval—social and cosmic disturbance—caused by a Daitya affecting human regions as well as Devas and Apsarās.
Indirectly, it underscores the Purāṇic ideal that rulers must protect their peoples from disruptive forces (adharma and violence). The mention of widespread agitation suggests the necessity of stable governance, defense, and dharmic order.
No explicit Vāstu or ritual procedure is stated here; the verse functions as a narrative-geographical notice listing peoples affected by a Daitya, rather than temple-building or rite instructions.
