Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
निरुत्साहं रणे तस्मिन् गतयुद्धोत्सवोद्यमम् ततः पतत एवास्य चर्म चोत्कृत्य भैरवम् //
nirutsāhaṃ raṇe tasmin gatayuddhotsavodyamam tataḥ patata evāsya carma cotkṛtya bhairavam //
In that battle he became spiritless, his former martial exhilaration and enterprise spent. Then, as he fell, his hide (skin/armour) was cut off, and a dreadful, terrifying cry arose.
This verse does not address pralaya; it focuses on battlefield psychology—loss of zeal, falling in combat, and the arising of terror.
It reflects Rajadharma/Kshatra-dharma indirectly: a ruler’s side must avoid collapse of morale in war, since loss of initiative (udyama) leads to defeat and भय (fear/terror) spreading through the ranks.
No Vastu or ritual procedure is specified here; the key takeaway is narrative imagery (fall in battle, cutting of armour/skin, and a fearsome cry) used to intensify the dharmic lesson about courage and consequence.
