PALM, n. A species of tree . . . of which the familiar "itching palm" ("Palma hominis") is most widely distributed . . . . This noble vegetable exudes a kind of invisible gum, which may be detected by applying to the bark a piece of gold or silver.
We never see a tree except through the image that we have of it, the concept of that tree; but the concept, the knowledge, the experience, is entirely different from the actual tree. Look at a tree and you will find how extraordinarily difficult it is to see it completely, so that no image, no screen, comes between the seeing and the actual fact. By completely I mean with the totality of your mind and heart, not a fragment of it.
