Matsya Purana — War of Devas and Dānavas: Yama and Kubera Defeated; Kālanemi’s Māyā and the A...
द्वितीयमिन्द्रजालेन योजितं प्रमुमोच ह संचारास्त्रेण रूपाणां क्षणाच्चक्रे विपर्ययम् //
dvitīyamindrajālena yojitaṃ pramumoca ha saṃcārāstreṇa rūpāṇāṃ kṣaṇāccakre viparyayam //
Then he released the second (device/weapon) that had been set in motion through Indrajāla; and by means of the Saṃcāra-astra, in an instant he brought about a reversal of forms (appearances).
This verse is not about Pralaya; it depicts Indrajāla (illusion) and an astra that instantaneously reverses appearances, emphasizing transformation rather than cosmic dissolution.
Indirectly, it reflects the Purāṇic idea that rulers must discern truth from deception—since Indrajāla signifies misleading appearances, the ethical takeaway is vigilance and discrimination (viveka) in governance and conduct.
No explicit Vāstu or ritual procedure is stated; the technical significance is martial-ritual vocabulary (astra/vidyā) used in Puranic narration, not temple architecture rules.
