The belief might easily arise that anyone now entering the spiritual world must unconditionally become a spiritual investigator himself. This is not necessarily so, although in my book, Knowledge of the Higher Worlds, I have described much of how the soul must transform itself in order really to be able to enter. And to a certain degree, everyone is able to do this today, but it need not be everyone. What a person develops regarding the soul element is a purely intimate concern; what arises from it, however, is the formation of concepts of the investigated truths. What the spiritual investigator can give is clothed in conceptions such as I have developed today. Then it can be shared. For what a person needs, it is quite immaterial whether things are investigated by himself or whether he accepts them from some other credible source. I am speaking here from a law of spiritual investigation. It is not important to investigate the things oneself. What is important is for us to have them within us, for us to have developed them within. Hence, we are in error if we believe that everyone has to become a spiritual investigator.
Today, however, the spiritual investigator has the obligation (as I myself have had the obligation) to render an account, as it were, of his path of research. This is due not only to the fact that everyone today can, to a certain extent, follow the path I have described without harm, but it is also because everyone is justified in asking, “How have you arrived at these results?” This is why I have described these things. I believe that even those who have no wish to become spiritual investigators will at least want to be convinced of how spiritual investigators arrive at the results that everyone needs today, the results of those who wish to lay the foundation for the life which must develop in human souls for human evolution today.
