4. The Eternal Forces of the Human Soul in the Light of Spiritual Science

And the doctrine of repeated lives on earth, which appeared so magnificently to people in a significant epoch of spiritual life in Lessing, it is time that it received a scientific basis today, in that man changes his inner being as he changes nature, in order to eavesdrop on its secrets through experiments. But in so doing, man becomes acquainted with the eternal in the temporal, and in so doing, man brings himself into connection with spiritual processes, just as he brings himself into connection with natural processes around him through science. By studying the physicality of man, we find the confluence of what we find in our studies of minerals, plants, and animals, in our contemplation of nature; we find it concentrated in man. Man is embedded in the bosom of nature, but he is also embedded in the spiritual life of the cosmos through the forces that he discovers within himself on the paths of the soul. And once the spiritual eyes and ears are opened, man looks into the spiritual world.
