首楞嚴義疏注經 4.504

4.504

「如太虛空參合群器，由器形異，名之異空；除器觀空，說空為一。彼太虛空云何為汝成同、不同？何況更名是一、非一？則汝了知六受用根亦復如是。」

"It is like great space blending with various vessels. Because the shapes of the vessels differ, it is called 'different space'; removing the vessels and observing space, space is said to be 'one.' How could that great space become the same or different for your sake, much less be designated as 'one' or 'not one'? You should know that your six receptive faculties are also like this."
