Third Lecture

When a person leaves their physical and etheric bodies during sleep, they live with their ego and astral body only in relation to the warmth that pervades the earth and the air that flows and breathes through the earth. They are torn away from everything that configures earth and water in the physical body. Man is truly torn out of everything that, I would like to say, the physical and etheric bodies do as earthly beings when they sleep. Of course, air and warmth also belong to the earth, but only to the earth, not to the parts of the earth. Now, for man as a spiritualized being, warmth is, so to speak, that in which he dwells as in his own element. In the higher animals, there is already a preparation for this. They have their own warmth, not just the warmth of their surroundings. They live in their soul, in their own warmth. Man has particularly developed this, that he lives in his own warmth, that he has his own temperature. This is something that separates him from the great variety of the outside world. Heat is, as it were, something that every human being carries within himself and carries with him. There he is in his actual self, there he is at home in the warmth.
