Traditional Chinese medicine starts from the viewpoint of “Heaven corresponds to man”, and believes that man is closely related to “nature”, that is, to the four seasons of climate change, and that the balance of yin and yang qi and blood in the body must be done from four aspects: environment, movement, diet and psychology. In the Nei Jing, when talking about “Yin and Yang Secret”, it is clearly stated that “The key to Yin and Yang is the solidity of Yang. If the two are not in harmony as in spring without autumn, as in winter without summer, and thus harmonize, it is called the holy degree.” This means that “the main key to the harmony of yin and yang is that yang must be densely and firmly guarded on the outside, forming a good physiological state of ‘righteousness exists within, evil cannot dry up’, that is, no disease; if yin and yang are out of balance, then the seasons of the natural environment are disordered, the climate is summer, and the patterns of cold, heat, temperature and cold are reversed. If once the yin and yang is out of balance, then the seasons of the natural environment are disrupted, the climate is summer, the rhythm of cold, heat, temperature and cold is reversed and disorderly, it will definitely affect the human body’s yin and yang disorder, and cause the disorder of qi and blood, and the disorder of the function of the internal organs and meridians and all kinds of diseases. Environmental balance. The sutra says: “in the heaven and earth and from the eight directions of the reason.” This means that human beings have to live peacefully and calmly between the yin and yang of nature, we must comply with the natural seasons, climate, wind, rain, clouds and other changes in the law to arrange their lives, food and rest, as well as work and exercise and other aspects of activity, which is the same as “cold plus clothes, hungry food”, is not to ignore the life of the The rule must be observed and followed. Balance of movement and static. Sutra says: “Form labor but not tired.” This means that people should participate in labor and exercise, but they need to master a “degree” according to each person’s individual situation. This is a scientific “appropriate for each person” dialectical argument, because participation in labor or exercise can exercise the muscles and bones, strengthen the body, but excessive and unlimited labor and excessive exercise, will lead to physical exhaustion, the formation of disease, damage to health, the loss is not worth it. Therefore, it is necessary to combine work and rest, which is what Chinese medicine calls “balance of movement and stillness”, in order to benefit health. Diet balance. The scriptures say: “Eat in moderation, careful and five flavors”, “blood to flow, coupled with dense”, “careful way as the law, long have a heavenly life.” That is to say: the diet should be regular, “according to the person, according to the time and according to the disease,” the appropriate adjustment of different people, different times, different circumstances, and to achieve the harmony of the five flavors, not to be partial food, so that people can live a healthy and happy life every day with a smooth flow of qi and blood, the camp and guard. If you can always comply with these dietary and nutritional health and wellness laws, you can expect to enjoy the gift of longevity! Mental balance. The sutra says: “The false evil and thief wind, avoid it sometimes, talk quietly about emptiness, the true energy from it, the spirit within the guard, the disease from the safe.” This means: when there is an abnormal climate that violates the laws of the seasons, it must be avoided in time. In terms of thoughts and emotions, it is important to maintain stability and cleanliness, tranquility and emptiness, no delusions, no greed, no comparison and no envy. This reminds people that in addition to preventing external causes of disease, should also prevent internal causes of disease. Maintaining good mental health is also an important rule of health.
