Matsya Purana — Uma’s Austerities and the Slaying of the Deceiver Asura ĀḌi
इत्युक्तो दानवेन्द्रस्तु तदाभाषत्स्मयञ्छनैः न चाबुध्यदभिज्ञानं प्रायस्त्रिपुरघातिनः //
ityukto dānavendrastu tadābhāṣatsmayañchanaiḥ na cābudhyadabhijñānaṃ prāyastripuraghātinaḥ //
Thus addressed, the lord of the Dānavas replied slowly, with a smile; yet he did not perceive the true recognition (or identity) of the slayer of Tripura, as is usually the case.
This verse does not discuss Pralaya directly; it highlights delusion and failed recognition in a Devasura narrative centered on Śiva as Tripuraghātin.
It implicitly warns rulers against pride and misjudgment: the Daitya lord’s smiling, casual reply and failure to recognize the greater power (Śiva) foreshadows political and moral downfall caused by lack of discernment.
Architectural detail is not explicit in this verse, but the keyword “Tripura” connects to the famed ‘three cities’ motif often linked with fortified cities and their destruction—used in Purāṇas to frame ritualized victory of dharma over adharma.
