Indra Slays Namuci—The Limits of Power and the Triumph of Divine Strategy
तत्राविनष्टावयवान् विद्यमानशिरोधरान् । उशना जीवयामास संजीवन्या स्वविद्यया ॥ ४७ ॥
tatrāvinaṣṭāvayavān vidyamāna-śirodharān uśanā jīvayām āsa saṁjīvanyā sva-vidyayā
అక్కడ ఆ కొండపై శిరస్సు, ధడము, అవయవాలు నశించని మృత దైత్యసైనికులను శుక్రాచార్యుడు తన సంజీవనీ మంత్రవిద్యతో పునర్జీవింపజేశాడు।
In this verse, Sañjīvanī vidyā is the life-restoring mantra/knowledge possessed by Śukrācārya (Uśanā), by which he revives fallen warriors whose bodies are not irreparably destroyed.
Śukrācārya is the preceptor of the asuras; during the Deva–Asura battle he uses his spiritual power to restore their fighting strength by bringing eligible fallen asuras back to life.
Power and knowledge can be used to restore and support one’s side, but the Bhagavatam context reminds seekers to align abilities with dharma and devotion rather than mere victory.
