अन्तवन्त इमे देहा नित्यस्योक्ताः शरीरिणः। अनाशिनोऽप्रमेयस्य तस्माद्युध्यस्व भारत॥
antavanta ime deha nityasyoktah sharirinah anashino'prameyasya tasmad yudhyasva bharata
Translation
These bodies of the eternal, indestructible, and immeasurable soul are said to be perishable. Therefore, fight, O Bharata!
Commentary
Krishna draws the practical conclusion - since the soul is eternal and only the body perishes, Arjuna should not grieve and must fulfill his duty. The body's death does not touch the immortal soul.
