Fifth Lecture

Now, simply due to their physical and bodily constitution, human beings can only come into contact with the spiritual world from their thirties onwards. Do not misunderstand me! Of course, if he turns to spiritual science, he can come into contact with the spiritual world earlier, even today; but if man, through his own development, which is bound to the physical body, is to receive spiritual forces from the universe, this can only happen if he remains capable of development well into his thirties. He does not. Therefore, from our point of view, there can be no question of human development progressing by natural means. It can only progress if humanity is fertilized by the science of initiation.
