In so many aspects, the most important thing is to "nourish the heart and adjust the spirit." Nourishing the heart and nature can be called "the way in the Tao", and conditioning the spirit is to condition the body first, which can be seen from the names of health-preserving monographs in previous dynasties. According to legend, Peng Zu's theory of keeping in good health in Shang Dynasty, Wang Qiao's Book of Nourishing Nature, and Tao Hongjing's Book of Longevity in Liang Dynasty are all summaries of keeping in good health. The main content of "sex" refers to psychological aspects, similar to the connotation of nourishing the heart. Therefore, the ancients put nourishing the heart in a prominent position and played a leading role. Three treasures of life-essence, qi and spirit, of which God is the most important, and God is the concentrated expression of essence and qi. The ancients said, "God is a car and Qi is a horse." "The Inscription of Nurturing the Gods" points out: "God is the son of Qi, Qi is the mother of God, and the shape of God's room ... When God goes, it will rot." God is born of qi and shape, but it plays a dominant role in shape, body, essence and qi, which is the value and symbol of their existence. The relationship between essence and god is vividly described as "spirit is like fire, essence is still oily" in the law of essence determination. Essence can be understood as the material basis of human body, and this material life activity can be summarized as the whole "God", such as the flame of a lamp. If a person wants to stay healthy and live a long life, he must grasp the three treasures of storing essence, storing qi and recuperating. Use god to store gas and concentrate. Here, I might as well give two simple examples to illustrate the relationship between psychology and life in health preservation. First, a few years ago, an 80-year-old man died in a car accident in Boston, USA. When the doctor dissected the corpse, he accidentally found that the blood vessels in the deceased were hardened, the heart was twice as big as normal, and there was chronic nephritis. The original blood supply to the liver was blocked, but a blood channel was opened nearby to replace it. Every disease of his is fatal, but I don't understand why he can still walk on the road. When asked about the wife of the deceased, he said that he had been living very well before his death, thought he was healthy and often walked around. This is because the deceased had an optimistic spirit and the idea of survival. As a result, he used the reserve force in his body to survive safely. In fact, people who are pessimistic and disappointed will get sick and can't live if they are completely healthy. A scientist put it well: "Hope is the antidote to all diseases, and survival is a powerful weapon for the mind to resist diseases." Then there was a Hungarian scientist who got diphtheria when he was young, and the doctor decided that he would not live long. At the age of 24, he was weak because of malnutrition. The doctor thought that he could only live for half a year at most, but he died at the age of 103 because he insisted on self-regulation. Spiritual factors play such an important role in people's life activities, so it should be the dominant aspect to adjust the mind and nourish the heart and cultivate sacrifices in health preservation. This is especially important for the health care of the elderly. Because the old man's essence is insufficient, his anger is easy to burn; Unknown eyes and ears, easy to get suspicious; The situation is not smooth, and there are a lot of depression. Therefore, we should not only pay attention to the straightness, quietness and slowness in our daily life, diet and actions, but also pay attention to the principle of calming our hearts and calming our nerves, and here we ask for the removal of bad emotions. On Aging, a hermit in the Yuan Dynasty, said: "It is not expensive to seek new ways to build old people's health. First, be a sage to break the illusory poetry, wash away the troubles in your chest, care about fame and fortune, and not be crazy about emotions ... God does not think evil. " You Jicheng's book "Prevention of Disease" contains: "People bother me less, and people are afraid that I will not be angry; Indifferent and complacent, this medicine for longevity. "
From this point of view, the way to preserve one's health is not to seek the elixir, but to cultivate one's mind and pay attention to mental health, so people are expected to be old.
