Matsya Purana — The Advent of Narasiṃha and Hiraṇyakaśipu’s Weapon-Assault
अव्यक्तप्रभवं दिव्यं किमिदं रूपमागतम् दैत्यान्तकरणं घोरं संशतीव मनो मम //
avyaktaprabhavaṃ divyaṃ kimidaṃ rūpamāgatam daityāntakaraṇaṃ ghoraṃ saṃśatīva mano mama //
“Born of the Unmanifest, truly divine—what is this form that has come forth? Terrible, a destroyer of the Daityas—my mind seems to tremble with anxious doubt.”
It frames the divine manifestation as arising from the “Unmanifest” (avyakta), a key pralaya idea: forms re-emerge from an unmanifest source, and the avatar appears as a cosmic corrective power amid crisis.
Manu’s reaction models discernment and reverent inquiry: when confronted by overwhelming power, a ruler should seek clarity about dharma and protection, rather than act rashly—an ethical posture emphasized throughout Purana-guidance to kings and householders.
No direct Vastu or temple-rule detail appears in this verse; its ritual takeaway is the recognition of a divya-rūpa (divine form) and the proper devotional response—wonder, humility, and inquiry—before proceeding with rites or decisions.
