Inside and Outside
The third step of symmetrical thinking is to pay attention to the relationship between the inside of a thing and the outside. This is also indeed useful for us to analyze what mechanism a thing has. All the things in nature have their own movements, each of which can be divided between the internal and the external movement. In addition, the internal and the external movement tend to form a symmetrical relationship. This reveals that whenever a thing changes the internal movement, its external movement is also affected by the change in the internal movement. As seen in this indication, the relationship between the internal and the external movement plays an important role in maintaining the structure of a thing.
This phenomenon, of course, can be applied to a human body, and allows us to find out how a human body causes skin disease for instance. As if a thing maintains the structure on the relationship between the internal and the external movement, a human body also maintains the structure on the relationship between the internal and the external organs. The internal and the external organs maintain the symmetrical relationship. Thus, when internal organs in a human body change their circumstances, they affect the external organs and cause disease there. This reveals that a human body causes skin disease by the change in the internal organs.
Thus, symmetrical thinking about the relationship between "Inside and Outside" teaches us an important problem hidden in modern medical science. For instance, a person suffering from skin disease, of course, consults a dermatologist. Although a delmatologist has certainly the wide knowledge about skin disease, he tends to make light of the relationship between the skin and the internal organs. Thus, if the skin disease results from the internal organs, a delmatologist will be unable to treat the skin disease completely. Perharps, the majority of delmatologists may say that the laboratory datas of the patients show no change and the patients appear to have no cause in the internal organs. This is because the background field of an organ is too large to show strong change; as a result, delmatologists will be unable to find out the fundamental cause of disease.
Modern medical science has no concept about the relationship among organs in a human body; this must be just the reason why any medical doctor makes light of the relationship between the skin and the internal organs. I do hope modern medical science to notice such a mistake, and to have a concept about the relationship among organs in a human body. When modern medical science makes good use of symmetrical thinking, it will be able to teach medical doctors how important the relationship between the skin and the internal organs is.
