In many circles where there is a striving toward mysticism, people feel particularly highly advanced; but it is a mysticism that leads to superficiality of the soul. With this superficiality, one does not penetrate the eternal mysteries of life. It only penetrates when one has the patience to awaken the slumbering forces of the soul or at least to let one’s thinking penetrate what the slumbering soul forces may find from stage to stage. The superficiality of the heart must be conquered. Victory over superficial mysticism can develop the ability to discover the powers of the soul, which lead in the right way from the temporary to the eternal, to the imperishable. That is what is genuinely able to work fruitfully in the most different areas of contemporary life.
