Let us suppose that we take into ourselves something of a mineral nature. Every such mineral substance must be so far worked upon within the human being that the following result is brought about. You know that we have our own individual temperature; in the healthy person this is about 98 degrees Fahrenheit (37° centigrade). In the warmth of our blood we have something which exceeds the warmth outside us. Everything which we take in as mineral substance must, however, be so transformed, so metamorphosed in our organism that, where the warmth of our blood exceeds the average warmth of its external environment, where it rises above the average external warmth of our surroundings, this excess of warmth absorbs with satisfaction the mineral element within us. If you eat a grain of cooking-salt, this grain of salt must be absorbed by your individual warmth, not by the warmth which you have in common with the outside world. It must be absorbed with satisfaction by your own individual warmth. Everything mineral must be transformed into warmth-ether. And the moment a person has something in his organism which prevents any kind of mineral from being changed into warmth-ether, at that moment he is ill.
