Mrs. Jung: I think we have already spoken of it; it is in the body, in matter.
Prof Jung: And what kind of matter? It is always that matter which the devil is especially keen on.
Mrs. Jung: The blood.
Prof Jung: Yes, because blood is the liquid spirit of life, the seat of the soul; one signs a contract with the devil with blood.
The devil wants that quite particularly because he knows its worth; anything done with blood or through blood is mighty important.
So arriving now on a level where the spirit is in the blood, in which part of the world do you push your head up through the crust? ~Zarathustra Seminars, Page 495
