2. Blood and Nerves

Our blood substance is quite different because it belongs entirely to the earth. Due to the inner composition of the blood, the processes taking place in it would really have to be completely earthly processes. The peculiar thing about them, however, is that they are not living processes. As you know, the mineral realm, the lifeless kingdom, developed during evolution on the earth. And the nature of our blood corresponds fully to this lifeless kingdom. Although our blood lives as long as it is in us, it is not destined for life by its inner, earthly nature. Strangely enough, our blood is alive only because it is connected to the cosmic element in us. Our nervous system is actually destined for life in the cosmos beyond the earth but is dead inside us; our blood, on the other hand, is meant to be dead in us and receives its life from outside. In a sense, the nervous system yields its life to the blood. Thus, the nervous system is dead while the blood is alive, comparatively speaking. Our blood is by its very nature dead on earth and has only a borrowed life, a cosmic life forced upon it. Life itself is not at all of our earth. That is why the nervous system must take death upon itself in order to become earthly, and why the blood has to become living to enable us as beings of earthly substance to turn to the world beyond the earth.
