No doubt we always write down on paper things belonging to the earth: the figures of ten, twenty and hundred - but things pertaining to the spiritual order of things, to the divine law, are of much greater importance. The notebook cannot contain them, it is not made for them. It is in the memory that they must be treasured, for memory is not only a recording machine. It is a fertile ground at the same time. What is put there is continually creative, it is doing something there. So one does not only possess something that one has deposited, there is its interest also.
