V. The Working Together of the Four Archangels
Everything that takes place externally in nature is different as soon as it enters a human being. No process within the human organism takes place in the same way as in outer nature. A flame that burns externally is dead fire; that which corresponds to it within the human being is flame living and ensouled: Just as a stove stands towards a lung, so does the external flame stand towards the living activity that goes on in the human organism when carbon unites with oxygen there—a process which, viewed externally, is indeed combustion in chemical terms. All spiritual progress at the present day depends on our being able to grasp these things in the right way. Suppose you take salt with your food, or eat some albumen or anything else, people assume that it remains just the same substance within you as it was outside. That is not true. Whatever enters the human being becomes different immediately. And the forces which make it different proceed in a quite definite way from those Beings whom I have pictured in the four Imaginations.
