Matsya Purana — War of Devas and Asuras; Birth of Aurva Fire; Countering Tamasī Māyā through ...
सा ददाह ततः सर्वान् माया मयविकल्पिता दैत्याश्चादित्यवपुषः सद्य उत्तस्थुराहवे //
sā dadāha tataḥ sarvān māyā mayavikalpitā daityāścādityavapuṣaḥ sadya uttasthurāhave //
Then that illusory power—conjured through magic and manifold deception—burned them all; and the Daityas, assuming the very forms of the Ādityas, instantly rose up again for battle.
It does not describe Pralaya directly; instead, it highlights māyā (illusory power) as a cosmic principle that can alter appearances and outcomes even in divine battles.
By portraying enemies who disguise themselves as allies (Daityas taking Āditya forms), it implies a dharmic lesson in vigilance and discernment—qualities expected of rulers and householders when judging people and situations.
No Vāstu or ritual procedure is stated in this verse; its technical focus is on māyā—illusion and deceptive manifestation—rather than temple-building or rites.
