首楞嚴義疏注經 4.15

4.15

"Furthermore, the Tathāgata has said that earth, water, fire, and wind are in their intrinsic nature harmoniously fused, completely pervading the dharmadhātu, serene and permanently abiding. World-Honoured One! If the nature of earth is all-pervading, how can it accommodate water? If the nature of water is all-pervading, then fire cannot arise. How, furthermore, can it be explained that the two natures of water and fire both pervade empty space without encroaching upon or extinguishing each other? World-Honoured One! The nature of earth is obstructing, whereas the nature of space is hollow and unobstructed; how can both completely pervade the dharmadhātu?"
