Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
मुमोच मुद्गरं भीमं सहस्राक्षाय संगरे दृष्ट्वा मुद्गरम् आयान्तम् अनिवार्यमथाम्बरे //
mumoca mudgaraṃ bhīmaṃ sahasrākṣāya saṃgare dṛṣṭvā mudgaram āyāntam anivāryamathāmbare //
In the battle he hurled a dreadful mace (mudgara) at Sahasrākṣa (Indra). Seeing that mace coming through the sky—irresistible—Indra braced himself to meet it.
This verse does not address Pralaya; it depicts a martial episode where a formidable mace is hurled at Indra, emphasizing irresistible force in Puranic warfare.
Indirectly, it reflects the Kshatriya ideal of confronting unavoidable danger with steadiness; the verse highlights the reality of conflict and the need for courage and readiness when threats cannot be averted.
No Vastu or ritual procedure is stated; the technical focus is on weapon imagery (mudgara) and the depiction of an ‘anivārya’ (irresistible) attack in the sky.
