Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
एते चान्ये च बहवो घोरोत्पाताः समुत्थिताः दैत्येन्द्रस्य विनाशाय दृश्यन्ते कालनिर्मिताः //
ete cānye ca bahavo ghorotpātāḥ samutthitāḥ daityendrasya vināśāya dṛśyante kālanirmitāḥ //
These—and many other—terrifying portents have arisen; they are seen as wrought by Time itself, for the destruction of the lord of the Daityas.
It does not describe Pralaya directly; it frames destruction as a targeted, time-ordained dissolution—Kāla manifests omens as instruments of inevitable ruin for an unrighteous power.
It implies that governance and conduct must align with dharma; when adharma dominates, signs of decline appear and Time brings consequences—an ethical warning for rulers and householders to correct course before collapse.
No Vāstu or ritual procedure is specified here; the key takeaway is the Purāṇic idea of “utpāta” as a diagnostic sign—used in ritual-astral traditions to interpret impending calamity.
