Matsya Purana — War of Devas and Dānavas: Yama and Kubera Defeated; Kālanemi’s Māyā and the A...
मुमोच शरवृष्टिं तु तस्मै यक्षाधिपो बली स तं दैत्यः शरव्रातं चिछेद निशितैः शरैः //
mumoca śaravṛṣṭiṃ tu tasmai yakṣādhipo balī sa taṃ daityaḥ śaravrātaṃ cicheda niśitaiḥ śaraiḥ //
Then the mighty lord of the Yakṣas loosed a rain of arrows at him; but that Daitya cut down the whole mass of shafts with his own keen arrows.
This verse is not about Pralaya; it depicts a martial episode, emphasizing Puranic warfare imagery—an arrow-shower neutralized by sharper counter-arrows.
Indirectly, it reflects the kṣātra ideal of vigilance and tactical skill: force must be met with disciplined counter-measures, a theme often applied to royal protection (rakṣaṇa) and defense of order.
No Vāstu or ritual procedure is specified here; the technical focus is on weaponry (śara, śaravṛṣṭi) and battlefield action rather than temple architecture rules.
