Life made creates life in the maker
The positive feeling I have described does not come merely from the activity of making. It comes about only when the field of living centers is actually achieved.
Indeed, cases of making where living structure is not achieved have a tense, unresolved feeling associated with them, that is more like frustration than satisfaction, even when a thing is actually made and finished.
In that sense, the art of making something living, once a person has experienced it, is sought again and again, avidly. It is like food. It carries its own reward. It seems immensely worth doing — over and above all other things.
