Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
सप्त धूम्रनिभा घोराः सूर्या दिवि समुत्थिताः सोमस्य गगनस्थस्य ग्रहास्तिष्ठन्ति शृङ्गगाः //
sapta dhūmranibhā ghorāḥ sūryā divi samutthitāḥ somasya gaganasthasya grahāstiṣṭhanti śṛṅgagāḥ //
Seven dreadful, smoke-hued suns arise in the sky; and the planets stand upon the Moon, which is stationed in the firmament, as though perched on its horns.
The imagery of “seven smoke-hued suns” and abnormal planetary positions is presented as a catastrophic celestial portent—an omen-class description commonly associated with impending large-scale upheaval, drought, or dissolution-like conditions.
As a nimitta (omen) verse, it implies vigilance: rulers and householders should respond to ominous astral signs with restraint, charity, protective rites, and dharmic governance—standard Purāṇic guidance when cosmic order appears disturbed.
No direct Vāstu rule is stated, but the verse functions as a trigger for śānti-karma (pacificatory rites). In temple/ritual practice, such portents are traditionally met with appeasement ceremonies to restore auspiciousness.
