Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
विषनिःश्वासनिर्दग्धं सुरसैन्यं महारथः ततो ऽस्त्रं गारुडं चक्रे शक्रश्चारुभुजस्तदा //
viṣaniḥśvāsanirdagdhaṃ surasainyaṃ mahārathaḥ tato 'straṃ gāruḍaṃ cakre śakraścārubhujastadā //
When the army of the gods had been scorched by poisonous blasts of breath, then Śakra (Indra)—the great chariot-warrior, strong-armed and splendid—thereupon employed the Gāruḍa weapon (Garuḍa-astra).
This verse is not about Pralaya; it depicts a battlefield crisis where the gods’ forces are burned by poisonous breath, prompting Indra to counter with the Garuḍa-astra.
Indirectly, it models rājadharma as decisive protection: a leader must respond swiftly with an appropriate remedy to a specific threat—here, Indra deploys a counter-weapon when his forces are endangered.
No Vāstu or temple-ritual rule is stated; the technical point is astric lore—Garuḍa is traditionally invoked as an antidotal force against poison/serpentine danger, reflected here through the Gāruḍa weapon.
