Second Discussion
We must be strict about this. When something enters the human organism, whether it is from some aggregate state or warm air and so on, it must undergo a change in the human organism – roughly speaking, within the human skin. Nothing is the same outside of and within the human organism. The human organism has to work through everything that comes from outside. No heating process may take place in the body as it does in stone, where a temperature simply passes through and warms the stone. If we are warmed from the outside, like an inorganic body, we process the warmth that approaches us so deeply that it is completely revitalized. If a cold occurs, even if it is an internal cold of the internal organs, it does not come from within, but from an external imposition of heat.
