Notes on the Design and Decoration of the Congress Hall
The two columns of the fourth picture represent the devouring red and blue blood tree. The cloud is the present-day air, which the larynx only controls. From this, the productive power of man, which creates into the solid, will arise in the future. Above the two blood columns, the initiated human being who has devoured the book will emerge. And man generates within himself the power that will transform the earth into the sun. This power is characterized in the face that is born out of the sun. When man has reached this stage, his vision is a vision into the astral world. This is indicated to you in the rainbow above the face of the sun. This rainbow indicates the power that man will have acquired when he himself becomes a cosmic creator being.
