अविनाशि तु तद्विद्धि येन सर्वमिदं ततम्। विनाशमव्ययस्यास्य न कश्चित्कर्तुमर्हति॥
avinashi tu tad viddhi yena sarvam idam tatam vinasham avyayasyasya na kashchit kartum arhati
Translation
Know that to be indestructible by which all this is pervaded. No one is able to cause the destruction of that which is imperishable.
Commentary
The soul pervades the entire body and is indestructible. No weapon, fire, water, or wind can destroy it. Understanding this removes the fear of death that paralyzes Arjuna.
