Matsya Purana — Vishnu’s Battle with the Daityas: Astra-Combat
भूर्दिशो विदिशश्चैव बाणजालमया बभुः दृष्ट्वा तदस्त्रमाहात्म्यं सेननीर् ग्रसनो ऽसुरः //
bhūrdiśo vidiśaścaiva bāṇajālamayā babhuḥ dṛṣṭvā tadastramāhātmyaṃ senanīr grasano 'suraḥ //
The earth—and the quarters and intermediate directions as well—became as though woven into a net of arrows. Seeing the might of that missile, the Asura commander, Grasana, was seized with dread.
It does not describe pralaya; it uses cosmic geography (earth, directions) to convey the overwhelming spread of an astra’s arrow-net across all space.
Indirectly, it reflects the kṣatriya sphere of protection and warfare: the proper use (and fear) of astras underscores disciplined martial power rather than domestic or royal administrative duties.
No Vāstu or temple-ritual rule is stated; the technical focus is on astra-lakṣaṇa (the manifested effect of a weapon), portrayed as an all-encompassing ‘net of arrows’ filling the directions.
