Matsya Purana — The Pushkara Manifestation
नक्तसंध्याभ्रसंकाशाः प्रादहंस्तिग्मतेजसः ते रुदन्तो द्रवन्तश्च गर्हयन्तः पितामहम् //
naktasaṃdhyābhrasaṃkāśāḥ prādahaṃstigmatejasaḥ te rudanto dravantaśca garhayantaḥ pitāmaham //
Resembling clouds at the darkening twilight, blazing with sharp radiance, they set things ablaze; and, weeping and fleeing, they reviled Pitāmaha (Brahmā).
It depicts terrifying pralaya-portents: blazing, cloud-like apparitions that burn things and drive beings into panic, even provoking blame against Brahmā—signaling breakdown of cosmic order.
Indirectly, it warns that in times of overwhelming calamity people lose restraint and turn to fear and blame; the ethical takeaway is steadiness, refuge in dharma, and disciplined conduct rather than panic-driven accusation.
No direct Vāstu or temple-rule is stated; the verse functions as a cosmological omen-description, useful ritually as a warning motif about inauspicious times rather than a construction prescription.
