5. The Inner Vitalization of the Soul through the Qualities of the Metallic Nature

This implies that we shall never understand the nature of disease in the sense I have described without Initiation-knowledge, for the physical properties of metals cannot cure disease. With an understanding of the physical attributes of metals it may well be possible to heal cerebral damage, but not disturbances of the circulatory fluids. What I have been saying is, in fact, not strictly accurate, for it is only the coarsest substance of the brain that can be healed. Fluids also circulate in the brain; therefore, in reality, one cannot heal cerebral damage with metals alone, but only with the aid of spiritual knowledge.
