【正确答案】In the West, parents tell their children "to follow the head, not the heart" and "not to be absent-minded while learning," whereas in China, since ancient times, there have been sayings such as "The heart is the very organ generating thought" and "All wishes, from the bottom of one's heart, may come true." Where is the activity of thinking taking place then—in the brain or in the heart? Scientifically speaking, "heart" in Western medicine and "xin" (heart) in traditional Chinese medicine are not the same thing. The former is purely a biological concept, while the latter is the "dwelling place of the spirit," filled with connotations of culture, philosophy, religion and even metaphysics, which are far beyond the domain of medicine. In traditional Chinese culture, man is viewed holistically as an inseparable unit of heart and mind, which is reflected in a common phenomenon where the concentrated mind may cause palpitations. Modern medicine, on the other hand, has also revealed that psychology is such a complicated functional process that all the relevant components of the body—not confined to the brain—are called upon to complete the task.
