Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
दानवेन्द्रं तदा चक्रे गन्धर्वास्त्रं महाद्भुतम् तदुत्थतेजसा व्याप्तम् अभूद्गमनगोचरम् //
dānavendraṃ tadā cakre gandharvāstraṃ mahādbhutam tadutthatejasā vyāptam abhūdgamanagocaram //
Then the lord of the Dānavas unleashed the wondrous Gandharva-weapon; pervaded by the radiance it generated, the entire field became a realm fit only for movement—an impassable, inescapable zone.
This verse is not about Pralaya; it describes a battlefield effect of a celestial weapon whose radiance envelops the area, emphasizing astric power rather than cosmic dissolution.
Indirectly, it reflects the Purāṇic idea that power (especially weaponry) must be governed by restraint and dharma—unchecked force can render a whole region perilous and unapproachable.
No Vāstu or temple-ritual rule is stated here; the technical focus is on astra-prayoga (deployment of a divine weapon) and its radiance-based, area-pervading effect.
