1925. This volume discusses an extension of the art of healing through spiritual knowledge. The authors had no thought of underrating the scientific medicine of their time. Their aim was to supplement the science already in existence by the illumination that can flow, from a true knowledge of the spirit, toward a living grasp of the processes of illness and of healing. Their purpose was to bring into new life, not the instinctive habit of the soul which still existed in the mysteries of ancient time, but a method of research corresponding to the fully evolved consciousness of modern man, which can be lifted into spiritual regions.
