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
在那里那座山上,舒克拉阿阇黎以自己名为“桑吉瓦尼”的咒术,使那些头颅、躯干与四肢未毁的阿修罗战士起死回生。
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.
