Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
अमुञ्चच्चार्चिषां वृन्दं भूमिवृत्तिर् विभावसुः गगनस्थश्च भगवान् अभीक्ष्णं परिदृश्यते //
amuñcaccārciṣāṃ vṛndaṃ bhūmivṛttir vibhāvasuḥ gaganasthaśca bhagavān abhīkṣṇaṃ paridṛśyate //
Vibhāvasu (the Sun), moving in his orbit around the earth, kept releasing clusters of blazing rays; and that revered lord, stationed in the sky, was repeatedly seen (thus) again and again.
It depicts an ominous intensification of the Sun’s fiery emission—an archetypal Purāṇic portent often used to signal cosmic imbalance and the approach of major upheaval or dissolution-like conditions.
As an omen-text, it implies vigilance: rulers and householders should respond to extraordinary celestial signs with restraint, dharmic conduct, and appropriate rites (śānti/propitiatory observances) rather than panic or adharma.
The verse itself is not a Vāstu rule; its practical ritual takeaway is the indication for śānti-karma (appeasement rites) when abnormal solar or fiery phenomena are observed—often a prelude in Purāṇas to prescribed remedial rituals.
