Thus you see how the number seven governs the whole of evolution. In the last few days we have given a skeleton outline of this, as it were, in the form of pictures, sometimes truly grotesque pictures, and in any case, such as deviate very much from what can be seen to-day in the physical world. If you conceive of it in this way it is approximately as if you were to erect the scaffolding for a house, the most external part that is intended to be used by the masons. That has, however, nothing to do with the subject; these are only thoughts about the subject, so to speak. We must rise from this purely intellectual scheme, which assists us indeed to understand, to the living structure, by using the pictures which are to be seen in the astral for the various conditions; then only have we what is called occult wisdom. As long as you build up a scaffolding you remain in the thought customary to you in the physical world. The whole scheme we have sketched is only physical thought. This is related to the full reality not at all like the inner framework of a house to the complete building, but only like the outer scaffolding upon which the builders stand. This has to be taken down again when the building is completed. In the same way the scaffolding of thought has to be taken down again if one wishes to have the truth before one as it really is. If one considers this abstraction as the reality, then one is not by any means speaking of true Spiritual Science but only of the concept which the man of the present day can form regarding the spiritual facts. The way in which spiritual facts are presented abstractly at the present time may be seen in such a diagram as I have made, but this in itself is unfruitful. I had to put it before you because we also need such a diagram, but fundamentally it is of no use to one who wishes to progress upon the truly spiritual path. If you describe the whole world, up to the highest spiritual facts, by means of such diagrams, this only has meaning for your present incarnation. In the next you must learn another diagram. This can only be thought by using the brain; it is only adapted for the brain. But as the brain disintegrates at death, the whole schematic presentation then falls to pieces. On the other hand, if you comprehend—at first in pictures of fantasy—that which really happens, what we have described as the consecutive pictures of the seals seen by spiritual vision, that is something which is not bound up with your physical brain, and which you retain because it does not originate from physical thinking, but from facts seen clairvoyantly. Therefore one must take care not to mistake for spiritual wisdom that which is striven for after the pattern of physical comprehension, which would also schematize the higher worlds. This is a description by means of the ordinary physical intellect. Of course, the physical intellect must play a part; on this account it is even useful to present such a diagram, and we may now carry it a step further.
