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.
Remorse is as the heart in which it grows; If that be gentle, it drops balmy dews Of true repentance; but if proud and gloomy, It is the poison tree, that pierced to the inmost, Weeps only tears of poison.
