In the past thousands of years, the sages have left us a lot of valuable wisdom. Although the times are changing and the society is changing, what remains unchanged is the philosophy and wisdom of these cautionary sayings.
Heaven and earth are big universes, and human beings are small universes. Traditional Chinese medicine closely links the human body with the universe through yin and yang-five elements-eight diagrams, forming a small universe. People live between heaven and earth (nature), and naturally they can't get rid of the influence of heaven and earth (nature), especially the physiological function of people, which is in line with the laws of nature.
The small universe of human body should conform to the big universe of heaven and earth, with spring in summer, long harvest in autumn and storage in winter. Just like nature, it germinates in spring, grows in summer, harvests in autumn and stores in winter.
"Huangdi Neijing" four qi tune the spirit, saying that the four seasons of yin and yang are the foundation of all things. Therefore, saints nourish yang in spring and summer and yin in autumn and winter to follow their roots, so they rise and fall with everything at the door of growth. If you violate its roots, you cut off its roots, which is really bad. Therefore, the four seasons of Yin and Yang, the end of all things, the foundation of life and death, its opposite is disaster, from which it is very difficult to get sick, which is the so-called Tao. Tao, sage and fool admire it. Born in yin and yang, died in opposition; Rule from it, chaos from it.
In modern terms, the change of Yin and Yang in the four seasons is the basis of the birth, growth, convergence and closure of all things. The reason why saints who know how to keep healthy nourish yang in spring and summer and yin in autumn and winter is to adapt to the fundamental law of keeping healthy, so they can be consistent with everything in germination, growth, convergence and concealment. Violating the fundamental law of keeping in good health will destroy the essence of human body and destroy it. Therefore, the change of yin and yang in the four seasons is the starting point and end point of everything, and it is the foundation of life and death. If you violate it, disaster will happen; And get used to it, you won't get seriously ill. Knowing this, we can say that we have mastered the way of keeping in good health. The way to preserve one's health is followed by saints and violated by fools. People can survive with the changes of yin and yang in four seasons, and die if they violate the changes of yin and yang in four seasons; The human body can function normally if it adapts to the changes of yin and yang in the four seasons, and it will be dysfunctional if it violates the changes of yin and yang in the four seasons.
The universe is big, but human beings are small. In the vast universe, human beings are just a grain of dust. Comply with the natural laws of the universe, conform to heaven, and everything comes into being; Violating the natural laws of the universe and heaven will only lead to extinction. Therefore, if you get this word, you will get more help, but if you lose it, you will get less help. Those who go with the sky prosper, and those who go against the sky die.
