XII. Christ, Ahriman and Lucifer

You see, you are all already so old, with the exception of the only one sitting among you, that you must have calcified your nervous system a little. Because if you still had your nervous system today as you had it when you were six months old, you would all be crazy. You can no longer have such a soft nervous system. Those people who are crazy have a childlike nervous system. So we have to have the power of hardening, of calcification within us. And on the other hand, we have to have the power of softening, of rejuvenation. These two forces must maintain a balance.
