Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
इति प्रगाढसंकटे सुरासुरे सुसंगरे भयं समुझ्य दुर्जया भटाः स्फुटन्ति मानिनः //
iti pragāḍhasaṃkaṭe surāsure susaṃgare bhayaṃ samujhya durjayā bhaṭāḥ sphuṭanti māninaḥ //
Thus, in that deeply perilous and evenly matched battle between gods and Asuras, the proud warriors—though hard to overcome—cast off fear and pressed on, striking and breaking their foes.
This verse does not address pralaya; it depicts a deva–asura battlefield mood, emphasizing courage and the casting off of fear during crisis.
It aligns with the Purāṇic ethic of steadfastness in adversity: a king (or any duty-bound person) should not abandon responsibility out of fear, but act with resolve when facing public danger or conflict.
No Vāstu or ritual procedure is stated here; the verse is purely martial and ethical in tone, highlighting valor in a perilous encounter.
