The entire Universe is Empty
When you look forward, if you become aware of the back of your eyes, there is nothing. An empty void is felt. We see the image formed on a part of the retina, just as we see the image projected onto the screen in a movie theater. If you bypass the amodal perception called "立体感" (stereoscopic effect/three-dimensionality) , you only see the image of a thin film, and beyond that, there is only empty space. Both in front of the screen and beyond it, everything is empty except for the film of the thin image. Therefore, if you perceive the mere illusion of the thin image as transparent , you can realize that the entire universe is empty.
