Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
ततो ऽस्य विविशुर्वक्त्रं समहारथकुञ्जरा सुरसेनाविशद्भीमं पातालोत्तानतालुकम् //
tato 'sya viviśurvaktraṃ samahārathakuñjarā surasenāviśadbhīmaṃ pātālottānatālukam //
Then the army of the gods—together with chariots and elephants—rushed into his mouth, dreadful and gaping, whose palate seemed uplifted like the very vault of the netherworld.
This verse is not a pralaya-teaching directly; it uses cosmological imagery (Pātāla) as a simile to convey the vast, terrifying scale of a gaping mouth in a battle episode.
Indirectly, it reinforces the Purāṇic ethic that adharma manifests as overwhelming, destructive force, while the sura-senā’s collective action models disciplined resistance—an ideal echoed in kingly duty to protect order.
No explicit Vāstu or ritual rule appears here; the significance is poetic-cosmological—invoking Pātāla to intensify the scene, a common Purāṇic technique for conveying magnitude.
