A Christmas Thought and the Secret of the Ego
We see the tree grow out of what forms the physical body for the earth, which was stamped in its earthly form by that which permits the human being to appear on the earth in a lower sphere than he would have if he had not gone through the Luciferic temptation. Something grows out of man's entire earthly existence that has come into humanity's evolution through the Luciferic misguidance, through the temptation. When we seek knowledge, we seek it in a different way than was originally predestined. This makes it appear that something different grows out of our earthly deeds from what would have been the case in accordance with the gods' original intention. We form an earthly existence that is not as the gods originally intended for us; we mix something else into it, and we must form very definite pictures of this if we wish to understand it. Definite mental images are required if we wish to understand, to understand properly.
