Matsya Purana — The Burning of Tripura and Rudra’s Victory
मर्तव्यकृतबुद्धीनां जये चानिश्चितात्मनाम् अबलानां चमूर्ह्यासीद् अबलावयवा इव //
martavyakṛtabuddhīnāṃ jaye cāniścitātmanām abalānāṃ camūrhyāsīd abalāvayavā iva //
For those who had resolved only to die, and for those whose minds were uncertain even about victory, the army became bewildered—like a body whose limbs are without strength.
This verse does not address Pralaya; it focuses on human psychology in warfare—how fatalism and uncertainty collapse collective strength.
For a king, it teaches that leadership must cultivate steady resolve and confidence; an army (and by extension a polity or household) fails when its members are weak and directionless.
No Vastu or ritual rule is stated; the simile of a body with weak limbs is used to explain organizational dysfunction, not temple architecture.
