"These words might be true, but they may also be entirely erroneous. They are true when understood in the sense of Angelus Silesius, or of Meister Eckhart, that is when they refer to the development of powers dormant in every human soul, which, from some such idea, endeavors to experience within itself the Christ of the Gospels. They are altogether wrong, if a more or less shallow ideal of the Christ is thus created out of the spirit of an age that acknowledges the truth of no perceptions other than those of the senses." The life of the Spirit can be understood only when we do not presume to criticize it with the lower mind, but rather when we develop it reverently within ourselves. No one can hope to learn anything of the higher truths if he demands that they shall be lowered to the "average understanding." This statement provokes the question: "Why, then, do you mystics proclaim these truths to people who, you declare, cannot as yet understand them? Why should there be Movements in the furtherance of certain teachings, when the powers which render men able to conceive of these teachings are still undeveloped?" It is the task of this book to elucidate this apparent contradiction. It will show that the spiritual currents of our day originate from a different source, in a different manner, from the science which relies entirely on the lower intellect. Yet, in spite of this, these spiritual currents are not to be considered as less scientific than the science which is based upon physical facts alone. Rather do they extend the field of scientific investigation into the superphysical. We must close this chapter with one more question, which is likely to arise: How may one attain to superphysical truths, and, of what help are spiritual movements towards this attainment?
