That is because the internal conditions of the body are always reflected on the exterior of the body".The four diagnostic methods examine and learn about the pathological conditions from different angle and aspect and find out the etiology and pathogenesis, thereby providing the basis for TDS. The four methods are related to and supplement one another. They cannot be separated from one another, each having its specific function that cannot be substituted for the others. In clinical practice, only when the four techniques are organically combined can a disease be understood all-sidedly. Thus, a correct diagnosis can be made.疾病发生时必有相关的病理改变引起的异常外在表现，正如《丹溪心法》所指出的：“欲知其内者，当以观乎外，诊于外者，斯以知其内，盖有诸内者形诸外。

This is because "all the vital essence from the five zang and six fu organs converges into the eyes." From the observation of vitality the physician may infer the abundance or inadequacy of the vital essence, analyze mildness or the severeness of the disease and predict the prognosis of disease. It is quite evident that the observation of vitality is of an important significance in diagnosing a disease.
