“What is a mirror? It’s the only invented material that is natural. Whoever looks at a mirror, whoever manages to see it without seeing himself, whoever understands that its depth consists of being empty, whoever walks inside its transparent space without leaving the trace of his own image upon it—that somebody has understood its mystery of thing. For that to happen one must surprise it when it’s alone, when it’s hanging in an empty room, without forgetting that the finest needle before it can transform it into the simple image of a needle, so sensitive is the mirror in its quality of lightest reflection, only image and not the body. Body of the thing.”
