All that we can produce in the way of ideals and artistic creativity — as also the natural healing forces in our body, which continuously compensate for the injuries life inflicts — originate not in our ordinary, rational minds but in the deeper forces that work in our early years on our orientation in space, on the formation of the larynx, and on the development of the brain. These same forces are still present in us later. People often say of the damages and injuries we sustain in life that external forces will not be of any help and that our organism must develop its own inherent healing powers. What they are talking about is a wise, benevolent influence working upon us. From this same source also arise the best forces that enable us to perceive the spiritual world — that is, to have true clairvoyance.
