Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
संमुखो निमिमातङ्गो जवनाचलकम्पनः स्रुतरक्तो बभौ शैलो घनधातुह्रदो यथा //
saṃmukho nimimātaṅgo javanācalakampanaḥ srutarakto babhau śailo ghanadhātuhrado yathā //
Facing them head-on, Nimi’s mighty elephant advanced, its speed shaking the mountain; and the mountain seemed to stream with blood, like a lake thick with mineral ores.
It does not describe Pralaya directly; instead, it uses cosmic-scale natural imagery (a trembling mountain, blood-like flow) to intensify a battlefield or portent-like scene.
Indirectly, it reflects the Purana’s valor-and-order ethos: disciplined force (symbolized by the war-elephant) and the grave consequences of conflict—reminding rulers to wield power responsibly.
No explicit Vastu or ritual rule appears; the key technical image is geological—“a lake dense with mineral ores”—used as a simile for the mountain’s blood-like appearance.
