III. What is Mysticism?

In justified mysticism, accordingly, spiritual science can recognise a stage which enables us to understand the real aim and intention of spiritual-scientific research. There is hardly anything from which we can learn as much in this respect as we can from a devoted study of the mystics. It must not be thought that the spiritual scientist, when he recognises something justified in mysticism, is denying the need for further progress. Mysticism is justified only if it is raised to a certain level of development, so that its methods yield results which are not merely subjective but give valid expression to truths concerning the spiritual world.
