Karma-Yoga, Jñāna-Yajña, and Avatāra Instruction
देही नित्यमवध्यो<यं देहे सर्वस्य भारत । तस्मात् सर्वाणि भूतानि न त्वं शोचितुमहसि,हे अर्जुन! यह आत्मा सबके शरीरमें सदा ही अवध्य है। इस कारण सम्पूर्ण प्राणियोंके लिये तू शोक करनेके योग्य नहीं है
dehī nityam avadhyo ’yaṁ dehe sarvasya bhārata | tasmāt sarvāṇi bhūtāni na tvaṁ śocitum arhasi ||
三阇耶转述其教：居于一切身中的“具身之我”，恒常不灭，永不可杀。故而，阿周那啊，你不应为一切众生而哀恸；因为纵在战阵杀伐之中，内在之人亦不被杀。悲伤起于将可坏之身误作不可坏之我。

Educational Q&A
The indwelling Self (dehī/ātman) in every body is eternal and cannot be slain; therefore grief based on the death of bodies is philosophically mistaken and ethically discouraged, especially when one must act according to dharma.
During the Kurukṣetra crisis, Sanjaya recounts the instruction given to Arjuna: to overcome paralyzing sorrow by recognizing the imperishability of the Self, so that he can act with clarity in the impending battle.
