8.156

「或言一處至於理實無」者，此約近、遠別見破。觀鏡、月像，見鏡即近，見像即遠，如觀井水。若有實色竝生，如何別見？既見不同，明知像假。即總結言：故知諸像於理實無。

"Or it is said that in one place [...] in principle they are non-existent": this refutes based on near and distant being seen differently. Looking at the mirror and the moon's reflection, one sees the mirror as near and sees the reflection as far, like looking into well water. If there were real forms arising side by side, how could they be seen differently? Since their appearances differ, it is evident that the reflection is nominal. Thus he concludes generally: therefore we know that reflections are in principle truly non-existent.
