Matsya Purana — The Burning of Tripura and Rudra’s Victory
अन्तरान्निर्गतश्चैव मायया स दितेः सुतः आजघान तदा शक्त्या शैलादिं समवस्थितम् //
antarānnirgataścaiva māyayā sa diteḥ sutaḥ ājaghāna tadā śaktyā śailādiṃ samavasthitam //
Then, emerging from within by the power of his māyā, that son of Diti struck at that moment with a śakti (spear), aiming at the mountain-like mass standing firm.
This verse is not about Pralaya; it depicts a combat episode where a Daitya uses māyā (illusion) to launch an attack with a śakti (spear).
Indirectly, it highlights the Purāṇic theme that power can be amplified by deception (māyā); for rulers, the implied ethic is vigilance against covert threats and the disciplined use of force.
No Vāstu or ritual procedure is taught here; the key technical term is śakti, a spear/javelin, used in a mythic battle setting rather than temple-architecture rules.
