What is perception, what is seeing? How do you see that tree? Look at it for the moment. With what sight do you see it? Is it solely an optical observation, just looking at the tree with the optical reaction, observing the form, the pattern, the light on the leaf? Or do you, when you observe a tree, name it, saying. “That is an oak” and walk by? By naming it you are no longer seeing the tree—the word denies the thing. Can you look at it without the word?
So, are you aware how you approach, how you look at, the tree? Do you observe it partially, with only one sense, the optical sense; or do you see it, hear it, smell it, feel it, see the design of it, take the whole of it in? Or, do you look at it as though you are different from it—of course, when you look at it you are not the tree. But can you look at it without a word, with all your senses responding to the totality of its beauty?
