IX. Errors of Spiritual Research

What do such people strive for? [They strive] to eliminate the personal, everything that comes from elsewhere than from the subconscious depths of the medium. That is why most is given to such revelations of mediums of which one can be certain that the mediums have not been in contact with the matter concerned in any way. If the medium speaks in a language of which one knows that it is unknown to him, then most is given to such revelations, and rightly so. What such persons strive for, who make use of mediums, can serve as an explanation. For even if spiritual research does not use anything that comes from this side, it is still true for the true spiritual researcher, who makes himself an instrument to penetrate into the spiritual worlds, that he must strip away the personal, that is, that which is only attached to his own soul life and is peculiar to his own soul life.
