Meditation on Silver. Man is brought into contact with that which comes over from earlier incarnations. Meditation on silver leads to the perception of spiritual warmth in the blood. This warmth is connected with the forces of reproduction. (Steiner 2010:7)
Pathological states. Blood should take its warmth from the spheres through which man has passed in previous incarnations, not from his present environment. Fever is the temporary separation of the circulation from its normal position within the chain of incarnations. For certain fever conditions, silver should be administered. (Steiner 2010:7)
Silver is the remedy for all diseases arising from karma. (Steiner 2010:7)
If a man concentrates on the peculiar properties of silver — and it is some time before the effects are registered — he concentrates within himself those forces which are responsible not only for the circulation of fluids through the vessels, but also for the circulation of warmth in the bloodstream. He then realizes that he owes his human status to the warmth circulating in his blood, in that he feels a certain inner warmth, a material, yet at the same time a spiritual element within his blood; and that in this warmth forces from former incarnations are actively working. In man’s relationship to silver is expressed that which can influence the warmth-activity of the blood and also that which provides a spiritual link with earlier incarnations. (Steiner 2010:35)
Silver therefore preserves that metallic virtue which reminds man of what survives in his present life from earlier incarnations. For the circulation of the blood with its remarkable warmth-differentiations is not derived from this physical world, nor from the world of Elements which I have described to you, nor even from the world of stars. The world of stars determines the course and direction of the blood circulation. But in the warmth of the blood that circulates within us there works the vitalizing force from previous lives on Earth. It is to this we appeal directly when we refer to forces of silver in their relationship to man. Thus the mystery of silver is related to his previous incarnations. Silver is one of the most astounding examples of the all-pervasiveness of the spiritual, even in the physical world. He who has a right understanding of silver knows that it is the symbol of the cycles of man’s lives on Earth. Hence the mystery of silver is bound up with reproduction and its secrets, because through the process of reproduction the being of man is perpetuated from generation to generation. The spiritual being who existed in former lives on Earth incarnates again through the process of reproduction. This is the same mystery as the mystery of blood. The mystery of the blood, of the warmth of the blood, is the mystery of silver. (Steiner 2010:35)
We are now familiar with the normal condition of man. Let us proceed to a study of his pathological states. Now the blood should not take its warmth from man’s present environment, but from the spheres through which he has passed in previous incarnations. Let us suppose that the warmth of his blood is affected by his present environment and is not activated by that which links us spiritually to previous incarnations. Pathological conditions then ensue. They occur because all that is connected with the warmth of the blood is severed from its natural associations, from earlier lives on Earth. What is fever? From the stand point of spiritual science fever occurs because the human organization has severed its relation with the cycle of incarnations. If, in some cases of illness, the doctor ascertains that the external world has worked upon the patient in such a way that his organization is in danger of being cut off from earlier incarnations, then the doctor administers silver  as a remedy. A very interesting case of this nature occurred recently in Dr. Wegman’s Clinic in Arlesheim. A condition such as I have described may suddenly occur in the spiritual life. Through external circumstances the human organization, owing to the peculiar characteristics of the blood, threatens to break away from previous incarnations. And this is precisely what happened recently in a particular case in Dr. Wegman’s Clinic. A patient who was convalescent suddenly developed an unexpectedly high temperature, a fever of unknown origin as it is described by orthodox medicine. With her intuitive understanding Dr. Wegman immediately administered a silver cure. When she told me about it the case revealed a complete picture of cosmic relationships. We learn from this of the interplay between what is connected with the spiritual evolution of man on the one hand, and on the other hand, with what leads to pathological conditions; and we learn how to treat them. (Steiner 2010:35-6)
The study, for example, of the metallity of silver which is an excellent remedy for all diseases associated with karma, leads on from the mystery of silver to other profound mysteries. We have thus spoken of virtually all those metallic natures that are related to the various conditions of consciousness in man. We will now extend our investigations into these conditions of consciousness, into the relationship to other worlds which man can establish through these conditions. In other words we propose in the next lectures to study in further detail the right path to spiritual knowledge. (Steiner 2010:36)
