Matsya Purana — War of Devas and Dānavas: Yama and Kubera Defeated; Kālanemi’s Māyā and the A...
इतरेषामसंख्याताः सुरजातिनिकायिनाम् जघ्ने स कोटीः संक्रुद्धश् चित्रास्त्रैरस्त्रकोविदः //
itareṣāmasaṃkhyātāḥ surajātinikāyinām jaghne sa koṭīḥ saṃkruddhaś citrāstrairastrakovidaḥ //
Then, in fury, that master of weapons slew countless crores of the hosts belonging to the various classes of gods, using wondrous and manifold missiles.
This verse does not describe Pralaya; it depicts a battle scene where an expert warrior annihilates divine hosts with celestial missiles.
Indirectly, it highlights kṣātra ideals—martial expertise and decisive action in conflict—though the verse itself is a mythic war report rather than a direct dharma injunction.
No Vāstu or ritual procedure is stated; the key technical idea is astravidyā (knowledge of missiles), expressed through terms like citrāstra and astra-kovida.
