5. Anthroposophy and Cosmology

Condensed in this way, the life of the soul can link itself with rarefied physical experience. When we begin to penetrate ourselves and thereby perceive how vitalized thought moves in our being of air, if I may so express myself, in which there are certain temperature variations, we gradually see how in fact differences of thought can also operate in our human organism. Thus, a sympathetic thought, for example the verdict: “Yes indeed, the tree is green,” does in fact induce a state of heat, whereas a thought in which antipathy is present, a negative judgment for example, has a chilling effect on our air-heat substance.
