Bhagavad Gita 2.17 — The indestructible
अविनाशि तु तद्विद्धि येन सर्वमिदं ततम्। विनाशमव्ययस्यास्य न कश्चित्कर्तुमर्हति ॥
avināśi tu tadviddhi yena sarvamidaṃ tatam | vināśamavyayasyāsya na kaścitkartumarhati ||
Meaning
Know that what pervades this whole universe is indestructible. No one can destroy that which never perishes.
