Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
रथाश्वान्सो ऽहनत्क्षिप्रं शतशो ऽथ सहस्रशः ततः सुराधिपस्त्वाष्ट्रम् अस्त्रं च समुदीरयत् //
rathāśvānso 'hanatkṣipraṃ śataśo 'tha sahasraśaḥ tataḥ surādhipastvāṣṭram astraṃ ca samudīrayat //
He swiftly struck down chariots and horses—by the hundreds and then by the thousands. Then the lord of the gods invoked and set in motion the Tvāṣṭra missile-weapon.
This verse does not describe Pralaya; it depicts a battlefield escalation where Indra responds to massive destruction by deploying a specialized divine weapon (the Tvāṣṭra astra).
Indirectly, it reflects the kṣatriya-ideal of decisive action and calibrated escalation—when ordinary force is insufficient, a ruler (or leader) is expected to employ stronger measures responsibly to restore order.
No Vāstu or temple-architecture rule is stated here; the closest ritual idea is the formal ‘invocation/activation’ of an astra (samudīrayat), implying mantra-governed deployment of power in Puranic tradition.
