Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
खेचराश्च सतीपुत्राः पातालतलवासिनः गणस्तथा परो रौद्रो मेघनामाङ्कुशायुधः //
khecarāśca satīputrāḥ pātālatalavāsinaḥ gaṇastathā paro raudro meghanāmāṅkuśāyudhaḥ //
There are also the sky-roaming beings, the sons of Satī, and those dwelling in the nether regions (Pātāla). Likewise, another fierce (raudra) gaṇa is mentioned—Megha by name—whose weapon is a goad (aṅkuśa).
This verse does not describe Pralaya directly; it catalogs classes of Rudra’s attendants across realms (sky and Pātāla), showing the Purāṇic cosmic ordering of beings rather than dissolution events.
Indirectly, it supports the Matsya Purāṇa’s broader ethic of governance through knowledge of cosmic hierarchy—kings and householders uphold dharma by honoring deities and their hosts through proper worship and restraint, acknowledging forces described as ‘raudra’ (fierce).
Ritually, the verse aids identification of Rudra’s gaṇas in Śaiva contexts; such catalogues inform offerings and invocations in worship. It does not give explicit Vāstu or temple-building rules, but it contributes to iconographic/ritual taxonomy (e.g., recognizing a gaṇa ‘Megha’ with an aṅkuśa).
