Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
तामापतन्तीं सम्प्रेक्ष्य मृगेन्द्रः शक्तिमुज्ज्वलाम् हुंकारेणैव रौद्रेण बभञ्ज भगवांस्तदा //
tāmāpatantīṃ samprekṣya mṛgendraḥ śaktimujjvalām huṃkāreṇaiva raudreṇa babhañja bhagavāṃstadā //
Seeing that blazing spear-weapon rushing toward him, the Lord—lion among beasts—then shattered it merely with a fierce, wrathful roar.
This verse is not about Pralaya; it highlights divine protective power in a battle context—showing that the Lord can neutralize destructive forces instantly.
It models the dharmic ideal of protection: like the Lord who stops a lethal threat, a king should safeguard subjects and a householder should defend dependents—using strength with restraint and purpose.
No direct Vāstu or temple-ritual rule appears here; the key takeaway is iconographic—“mṛgendra” evokes lion-like divine imagery often used in Purāṇic descriptions of protective forms.
