Health preservation is one of the highest realms pursued by China people. The ancients believed that there were three treasures in the sky, the sun, the moon and the stars, the earth, fire and wind, and people. What is spirit? Essence is the essence of things. Look at the word "Jing". On the left is the word "rice", and on the right is the simplification of the word "raw". Below the word "raw" are "moon" and "moon", which used to mean "meat" in ancient times. "Rice raw meat" is essence, which refers to the essence of food. The first thing to keep healthy is a good diet. Rice and meat, one meat and one vegetable, are matched with meat and vegetables. A good diet lies in a balanced nutrition. The word "food" that we commonly use now also means this. On the left side of the word "diet" is "moon (meat)", and on the right side is grass, which is vegetarian, indicating that the diet should be combined with meat and vegetables to achieve balance, which is the first priority of health care. The essence is mainly obtained from a good diet. The word "moon" in the ancient word "essence" is also a variant of the word "Dan", which means that Dan came out of a well, and the word "destiny" on it shows that a good diet is the best panacea. Qi, the word "Qi" in Oracle Bone Inscriptions, is three horizontal lines with different lengths, indicating that the ground gas is transpiration and reaches the sky. Why is it three horizontal? Three horizontal symbols of heaven and earth, the sky is above, the earth is below, and people live in it. Laozi said, "Everything is born." Everything in the world, including people, is produced by the accumulation and dispersion of qi. Qi flows and communicates between heaven and earth and has the energy to promote the growth of all things in heaven and earth. For people, where does qi come from? From the diet. Look at the word "eat", why "eat" is begging, it is "eat and replenish qi" to improve diet and "practice essence". Broadly speaking, everything is alive. Specifically, there are three kinds, that is, the meaning expressed by the three ways of writing qi. The first is external air. For people, air is the basic demand of human life. A good environment is also important for human survival. For the environment, we often use "local gas" and "clean gas"; The second is the qi of food, which can be written in the word "rice", which is actually the essence that is often said in health care; The third is the vitality of the human body, which Taoism calls "qi". Look at the word "God" again. The word "God" consists of two words: Yes and God. The word "yes" has two horizontal lines, the top represents the sky, and the bottom is the word "Xiao", which is the image of the sun, the moon and the stars. "God" is the pictograph of lightning. The ancients believed that lightning was boundless and mysterious, so they worshipped it and regarded it as a god. Lightning is one of the most primitive gods worshipped by the ancients, the representative of heaven and the master of all things. The human body is also a small world. Therefore, in the human body, God represents the supreme master of human beings, and is the thought, mind, spirit and soul of human beings and their manifestations. We often say "temperament", "spirit", "heart" and "righteousness". It can be said that God is also a kind of Qi. China's health preserving theory and even China's philosophy are often monistic, and consciousness and matter are not antagonistic. Between "God and things", "Qi" is unified into one. Vitality is an important part of China's traditional health preservation and health preservation theory. "The Collection of Lingshu Ben" said: "Those who store sperm are the masters of the five zang-organs, so they should not be injured, and the injured fall and suffer from yin deficiency; Yin deficiency means qi deficiency, and qi deficiency means death. " From this passage, we can also see the relationship between the three. Five hidden essences, essence is the home of God, and only with essence can there be God, so "accumulating essence" can we understand God. If the essence is hurt, God will give up, just to fall. This is the relationship between essence and god, that is, essence is the body and god is the use. Essence is not only the home of God, but also the mother of Qi. Lack of essential qi leads to suffocation, and people die without qi. Spirit and essence are the foundation and the ground; God is the master, not the sky. In the free exchange of qi, hair growth is the "spirit" of metaplasia. Therefore, Taiping Jing said: "God is subject to heaven, essence is subject to earth, and qi is subject to neutralization." The three are unified in Qi, mutually reinforcing and promoting each other. We can make an analogy: practice is like a fire in the forest. Essence is fire, qi is wind, and God is light and heat. When there is a fire, the air flows-the stronger the wind, the greater the fire. The greater the wind and fire, the greater the light and heat. However, fire needs trees to light it. In essence, this "forest" is a reasonable dietary nutrition. China's traditional way of keeping fit emphasizes vegetarianism. For the average person, vegetarianism is easier to keep fit, but people with high mental and physical labor intensity should also supplement meat and balanced nutrition appropriately to supplement the consumed essence. Let's talk about invigorating qi first. To nourish qi, we must first pay attention to the qi of the environment. We all like to live in a place with clean environment and fresh air. Noisy environment and dirty air are not good for health, let alone keeping in good health. There is a saying in Su Wen's "Ancient Innocent Essays" that "breathe the essence and keep the spirit independently". Breathing is a kind of breathing and health preservation, thus communicating the essence inside and outside. Why do people who have always been healthy like to live in seclusion in the mountains? Just to have a good environment and absorb the essence of heaven and earth. We live in a city, and we should try to live in a quiet and clean environment. Secondly, we should pay attention to the nature of food. As mentioned above, attention should be paid to a balanced diet, and the combination of meat and vegetables varies from person to person. Nourish the spirit again-nourish the spirit. Confucianism pays attention to moral cultivation and cultivates people's spirit with moral cultivation. Mencius even suggested that cultivating "noble spirit" is actually moral meaning. Tao Yuanming's poem said: "Building a house is under human conditions, but there are no chariots and horses;" Ask what you can do, your heart is far from self-prejudice. "Have a good attitude, even if you live in a noisy environment, it is like being in a remote and clean place. Most people who live a long life are open-minded, kind-hearted and gentle. Traditional Chinese medicine believes that people have emotional changes, also known as "seven emotions." Among them, anger, joy, worry and fear are five aspirations, which are closely related to the five internal organs. In Neijing, anger hurts the liver, and sorrow wins anger; Happiness hurts, and fear overcomes happiness; Thinking hurts the spleen, and anger overcomes thinking; Sad lungs, joy wins sorrow; Fear hurts. Kidney, thinking overcomes worry "and other theories. This view has been applied to health preservation by physicians in past dynasties, which plays an important role in regulating emotions, preventing and eliminating diseases, and prolonging life. Buddhism and Taoism also attach great importance to spiritual cultivation, such as humility in practice and compassion in learning Buddhism. Modern medicine also proves that human spirit can affect physical health. The fundamental purpose of cultivating the above three qi is to cultivate the internal vitality of the body. On this basis, through the method of guiding qi, for example, ordinary people can exercise reasonably, practice Qigong, Taoist practice Neidan, Buddhist meditation and so on. , enhance their own vitality, further promote the transformation of essence and qi, achieve the unity of essence and qi, and achieve the highest state of health preservation. As the saying goes, "Life lies in exercise". Correct exercise not only exercises muscles, but also often involves breathing and guiding qi to promote the operation of essence. In fact, it is to promote "practicing qi and essence" and "practicing spirit and spirit", so as to achieve the effect of nourishing the mind. Therefore, after exercise, you will often reach a state of full spirit and pleasure. However, excessive or inappropriate exercise may lead to mental injury, anger and fatigue, and the result is counterproductive. (China Traditional Chinese Medicine)
