Matsya Purana — The Devasura War: Tumult
*सूत उवाच सुरासुराणां सम्मर्दस् तस्मिन्नत्यन्तदारुणे तुमुलो ऽतिमहानासीत् सेनयोरुभयोरपि //
*sūta uvāca surāsurāṇāṃ sammardas tasminnatyantadāruṇe tumulo 'timahānāsīt senayorubhayorapi //
Sūta said: In that exceedingly dreadful clash between the gods and the asuras, a tumult of overwhelming magnitude arose on both armies’ sides.
This verse does not describe Pralaya directly; it portrays cosmic-scale disorder as battle-noise and devastation, a common Purāṇic motif that contrasts with the restoration of order (dharma) after conflict.
Indirectly, it frames the Purāṇic ethic that society must resist adharma: just as devas and asuras contend for cosmic order, a king is expected to restrain chaos and protect stability, while householders support order through righteous conduct.
No explicit Vāstu or ritual procedure is stated here; the verse functions as narrative scene-setting for a battle episode rather than temple-building rules or liturgical instructions.
