首楞嚴義疏注經 3.28

3.28

"Why is this? If it came from stillness, movement would then be extinguished, and one should not hear movement. If it came from movement, stillness would then be extinguished, and one should have no perception of stillness. If it arose from the faculty, there would certainly be neither movement nor stillness. Thus, the substance of hearing originally has no own-nature. If it emerged from space, having hearing as its nature it would not be space. Furthermore, if space itself hears, what does that have to do with your sense entrance?"
