首楞嚴義疏注經 3.131

3.131

"If it is born from space, when you consume empty space, what flavor should it have? If empty space inevitably had a salty flavor, then as it salted your tongue, it would also salt your face, and the people of this world would be identical to ocean fish. Constantly experiencing saltiness, they would have no inkling of blandness; if they did not recognize blandness, they would not perceive saltiness either. If they inevitably know nothing, how could it be called flavor?"
