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?
— Jiddu Krishnamurti – The Flame of Attention (p. 34)
Whatever good or bad things appear to us seem to exist from the side of those objects. How do they exist? If they exist from the side of the object, then, contemplating the basis of imputation, which lies out there at finger-point, we should see whether it is the object in question or not. Let us take for example a physical object and examine its shape, color and so on to see if that object is to be found anywhere among those attributes. If we do so, we find nothing that is the object in question. If we take a person as an example, and inspect the individual aggregates that are the bases of designation of a person, we find that none of them is the person. In that way we recognize that the imputed object is not to be found upon investigation.
Then if we contemplate how things appear to the mind, we see that they seem to exist from the side of the object, without dependence upon anything else. But when they are sought analytically, they are not found. They do exist, for they can help or harm us. But when pondering the manner in which they exist, we find no basis for the assumption that they exist from the side of the object. Thus, they exist by the power of subjective convention, by the power of designation.
When pondering the nature of existence, we find that entities are not found upon seeking them analytically. So they exist by means of conventional, conceptual designation. They do undeniably exist. But as long as they do not exist independently, from their own side, they must exist by the power of subjective convention. There is no alternative. An entity exists due to its being designated upon something that is not it.
