Notes on the Design and Decoration of the Congress Hall
The state that will occur when this has happened is symbolized in the Holy Grail of the narrated image. The transparent cube below represents a transparent diamond cube made of pure carbon. When man has progressed to the point where he uses carbon itself to build his body - without the help of plants - he will create the cube. This cube of crystallized pure carbon is the best indication of the future state of man. Man will have progressed so far that he will not only recognize the three dimensions, but also the oncoming contra-dimensions: hence the three other dimensions meet the three in the mirror image. These counter-dimensions represent what man will one day achieve when he has overcome the physical in spirit. The serpents signify the upward development to the higher. This is indicated in the seal in violet-bluish coils as a luminous image. This luminous image of the serpent signifies the devoted nature of knowledge. Only this devoted nature can grasp the world spiral in the Caduceus, which will then be fiery, which winds itself out of pure knowledge. Then it transforms into the downward-pointing pure chalice. The chalice of the plant is today directed upwards, pure and chaste; in man it is the other way round. But the human chalice will again be chaste and will turn downwards - that is why the Grail is represented here as a chalice turned downwards. The pure man, the man who has become innocent, is represented by the dove. The rainbow indicates the sevenfold creative man.
