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

What I now propose to say about the metallity, the real substantiality of the mineral world, should be accepted with the due reserve to which I drew attention yesterday when I said that the inner vitalization of the soul through the qualities of the metallity—in other words, the development of an inner communion with the metallity in a moral sense—is a necessary part of man's spiritual development today. The administration of metallic potentization to the human organism is the function of the medical practitioner. And so I ask you to accept with due reserve what I shall say about the unknown factors of metals, other than those already discussed. The mystery of mercury in particular has a special significance for those who approach the world from a spiritual angle, that is to say, for those who are able to perceive the spiritual operating in physical substances. The metal mercury is only one part of what spiritual science calls in general terms the mercurial. The mercurial includes everything that has the characteristics of liquid metals; in nature as we know it today, there is only one metal that shares these characteristics and can be regarded as mercurial, namely, quicksilver. But this is only one member of the mercurial species. In spiritual science the mercurial includes everything of a mercurial nature; quicksilver is looked upon simply as a typical example of the mercurial.
