Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
संध्यमाने ततस्त्वाष्ट्रे निश्चेरुः पावकार्चिषः ततो यन्त्रमयान् दिव्यान् आयुधान्दुष्प्रधर्षिणः //
saṃdhyamāne tatastvāṣṭre niśceruḥ pāvakārciṣaḥ tato yantramayān divyān āyudhānduṣpradharṣiṇaḥ //
Then, as the work of Tvāṣṭṛ was being set in motion at that critical juncture, tongues of fire burst forth; and from it emerged divine weapons, fashioned as marvels of mechanism, irresistible to assail.
This verse is not about Pralaya; it highlights creative manifestation—fiery energy (Agni) issuing from Tvaṣṭṛ’s craft and producing divine, engineered weapons.
Indirectly, it supports the Purāṇic ideal that righteous power and protection rely on divinely sanctioned means—tools and arms should serve dharma, not mere aggression.
The key term is yantra-maya—suggesting specialized engineered devices used for sacred or royal purposes, aligning with Matsya Purāṇa themes of Vāstu/technical knowledge applied to divine implements.
