"God" is born of innate essence, and when the embryo is formed, the God of life is born. God is in the first place in the human body, and only with God can all human life activities take place. People's life activities can be divided into two categories: one is physiological activities which are mainly based on material and energy metabolism; The other is mental activity. The Book of Supporting the Aged and Caring for Relatives says: "The subject is God", which shows that in the unified whole of the human body, it is the mind that plays the role of commander and coordinator. Life activities can only show the overall characteristics, functions, behaviors and laws of various organs and tissues under the regulation of the commander-in-chief of the mind. In other words, people's physical movement is dominated by spiritual consciousness; People's mental state is closely related to physical function. Under the same harsh environmental conditions, strong-willed people will suffer much less physical and mental damage than weak-willed people. It can be seen that health care must raise the heart, not only pay attention to physical health, but also pay attention to mental health. However, before this century, the problem of maintaining mental health has not received long-term attention. When it comes to health, it seems to mean good health. Some people even think that no disease is health. These are obviously wrong. The so-called health, not only refers to a person's physical normality, no disease and no weakness, but also includes a good mental state and social adaptability.
