Erich Maria Remarque. Black Obelisk (№ 264617)

I... suddenly again deeply amazed by the things beyond this world so close, there is a huge reality, living by a different set of laws, and that this head, which I can easily get my arms around, sees things differently than I do, - every tree, every star, every relationship between people and herself. It is another universe. And for a moment all mixed in my brain, and I don't know what is true reality - what I see or what she sees or that happens without us, and what we will never know, because in this case the same thing happens that with the mirrors, they are here when we are here, but always reflect only our own image. For nothing, for nothing we do not know what they are, when left alone, and what lies behind them.
