15. How Are the Eternal Forces of the Human Soul Investigated?

For some centuries now, I would say, natural science has had to educate humanity to a sense of reality that did not exist in the past. The time could come – and it has now come – when, with the same rigor in the development of inner soul forces, man can also speak about the spiritual world. And even if today all the reasons that have already been mentioned are still being objected to this spiritual science – this spiritual science will become as much a part of the spiritual development of humanity as natural science has become a part of it. What is today taken for granted in natural science was, relatively recently, still fought against, fought against in the worst way. That which is fought against today in spiritual science will become a matter of course, like certain achievements in natural science. But then the time will come when people will realize that just as everyone does not have to be an astronomer to understand what astronomy contributes to general knowledge and to convey to the world, so too does not everyone need to be a spiritual researcher. Today, anyone can become one to a certain extent, as can be seen from my book 'How to Know Higher Worlds'. But it is not even necessary. It is just as little necessary as it is necessary, in order to understand a book, to have the gift of writing that book oneself. When the truths about the spiritual world have been brought forth by this spiritual world through this or that spiritual researcher, then ordinary human comprehension is enough to understand what the spiritual researcher says - not just to believe it, but to really absorb it and have it as soul food. So that even in such difficult times as these, when we are surrounded by hundreds and hundreds of deaths every day, we can develop an even greater awareness of the eternal significance of the human soul and the everlasting eternal powers that underlie the human soul.
