Matsya Purana — Origin of Soma
अशेषसत्त्वक्षयकृत्प्रवृद्धस् तीक्ष्णायुधास्त्रज्वलनैकरूपः शस्त्रैरथान्योन्यमशेषसैन्यं द्वयोर्जगाम क्षयमुग्रतीक्ष्णैः //
aśeṣasattvakṣayakṛtpravṛddhas tīkṣṇāyudhāstrajvalanaikarūpaḥ śastrairathānyonyamaśeṣasainyaṃ dvayorjagāma kṣayamugratīkṣṇaiḥ //
The battle swelled into a force that brought about the destruction of countless living beings; it appeared as a single blaze of sharp weapons and flaming missiles. Then, striking one another with fierce and keen arms, the entire armies on both sides went to annihilation.
It is not a cosmic pralaya passage; it uses pralaya-like imagery to portray battlefield kṣaya—total destruction—showing how violence can mimic a world-ending conflagration on a human scale.
By emphasizing mutual annihilation as the end-result of unchecked warfare, it indirectly supports the Rajadharma ideal that a king should employ force only when necessary and with restraint, aiming to protect subjects rather than escalate slaughter.
No Vāstu or ritual procedure is stated in this verse; its primary function is martial narration, using ‘blazing weapons’ as a literary image rather than a technical ritual/architectural instruction.
