Matsya Purana — Vishnu’s Battle with the Daityas: Astra-Combat
ततो ऽस्त्रतेजसा सर्वं व्याप्तं लोकं चराचरम् ततो बाणमयं सर्वम् आकाशं समदृश्यत //
tato 'stratejasā sarvaṃ vyāptaṃ lokaṃ carācaram tato bāṇamayaṃ sarvam ākāśaṃ samadṛśyata //
Then, by the blazing potency of the missile-weapons, the entire world—moving and unmoving—was pervaded; and the whole sky appeared completely filled with arrows.
It uses pralaya-like language—“pervading” the whole moving and unmoving world—to convey an all-consuming force, suggesting how overwhelming divine power can resemble cosmic dissolution in its totality.
Indirectly, it underscores that unchecked force engulfs all realms; in Matsya Purana’s ethical lens, rulers must wield power with restraint and dharma, since violence impacts both the living and the non-living order of society.
No direct Vastu or ritual procedure is stated; however, the imagery of space being “filled” can be read symbolically alongside ritual concepts where a field (kṣetra/ākāśa) is pervaded by energy—useful for interpretive cross-referencing, not as a literal Vastu rule.
