The problem with trees Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as: HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS only to find a reference to another leaf: Please see HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.

The Japanese Perspective An Essay from The Beauty of Everyday Things by Yanagi Sōetsu Generally speaking, the Western perception of art has its roots in Greece. For a long time its goal was perfection, which is particularly noticeable in Greek sculpture. This was in keeping with Western scientific thinking; there are no painters like Andrea Mantegna in the East. I am tempted to call such art ‘the art of even numbers’. In contrast to this, what the Japanese eye sought was the beauty of imperfection, which I would call ‘the art of odd numbers’. No other country has pursued the art of imperfection as eagerly as Japan.

The true meaning of tea There is no true deformation that does not follow the laws of necessity. In later years, when deformation came to be consciously created, when the rejection of perfection became a matter of deliberate manipulation, the true meaning of tea began to be lost. To put it in somewhat contradictory terms, true tea existed only before the advent of the tea ceremony. After the coming of tea, when deformation came to be consciously sought, common everyday beauty disappeared and unnatural manipulation began. food
One receives with an empty hand Intuition means to see immediately, directly. Considered as a form of activity, the seeing eye and the seen object are one, not two. One is embedded in the other. People who know with the intellect before seeing with the eyes cannot be said to be truly seeing. With intuition, time is not a factor. It takes place immediately, so there is no hesitation. It is instantaneous. Since there is no hesitation, intuition doesn’t harbour doubt. It is accompanied by conviction. Seeing and believing are close brothers. seeingintuition
Only when it has ceased to be a pattern Here I would like to append three lines in praise of muji: A pattern that is not a pattern is a true pattern. Create patterns until they are no longer patterns. The true pattern is a patternless pattern. When creating a pattern, one’s heart must also be muji. A pattern must be followed through until it is no longer a pattern. It is a true pattern only when it has ceased to be a pattern. zenpatterns
