楞伽阿跋多羅寶經註解 4.198

4.198

「譬如恒沙是地自性，劫盡燒時燒一切地，而彼地大不捨自性，與火大俱生故。其餘愚夫作地燒想，而地不燒，以火因故。如是大慧！如來法身如恒沙不壞。」

"For example, Mahāmati, the Ganges sands have the intrinsic nature of earth. When the eon is consumed at its end, all earth is burned, yet that great element of earth does not abandon its intrinsic nature, because it co-arises with the great element of fire. Other foolish people imagine that the earth is burned, yet the earth is not burned, due to its cause in fire. Just so, Mahāmati, the Tathāgata's dharmakāya is indestructible like the sands of the Ganges."
