The three months of summer are the season of lush vegetation in nature. In this season, the weather drops, the atmosphere rises, the atmosphere of heaven and earth blends with each other, and plants blossom and bear fruit and grow vigorously. People should go to bed late and get up early, don't hate the long days, keep their mood cheerful, don't be angry, and make their faces as beautiful as flowers in bud; It also makes Qi-flowing freely, full of energy, and has a strong interest in external things. These are all ways to adapt to the summer climate and maintain the long-term cultivation of Qi. If these methods are violated, it will damage the heart, weaken the ability to supply qi for autumn convergence, lead to malaria in autumn, and get sick again when winter comes.
The three months of autumn are the season when everything in nature matures, calms down and converges. At this time, the weather is urgent and the atmosphere is clear. People should go to bed early and get up early, and get up in the morning at the same time as the crow. Keep the mood calm, so as to alleviate the harm of the cold air in autumn to the human body; At the same time, the spirit should be kept inside, so that the cold air in autumn can be peaceful; Don't make your will run away to keep your lungs clear. These are all ways to adapt to the characteristics of autumn and maintain the convergence of human body. If these methods are violated, it will damage the heart, weaken the ability to supply the gas sealed in winter, and lead to diarrhea in winter.
The three months of winter are the season when vitality lurks and everything is hidden. At this time, the water becomes ice, and the ground freezes and cracks. People should not disturb the yang in their bodies. They should go to bed early and get up late until the sun shines. Don't worry about things, make your thoughts and emotions calm and hidden, as if you have gained something without showing your emotions; Avoid the cold, tend to be warm, and don't make the skin sweat and lose the yang. This is a way to adapt to the winter climate and maintain the human body's closed qi. If these methods are violated, the kidney will be depleted, which will weaken the ability to supply qi for spring hair growth, leading to paralysis in spring.
The weather is clean and bright. Because Tiande is hidden and running endlessly, it can be kept forever. If the weather is gloomy, the sun and the moon will lose their brilliance, and evil spirits will take advantage of it, resulting in disasters, which will lead to the blockage of yang, the dark and turbid atmosphere will obscure the light, the clouds will be filled, and the rain and dew will not fall. If the qi of heaven and earth don't blend, the life of all things can't be prolonged, and even the huge trees with strong vitality in nature will die. Evil and surly qi does not spread, wind and rain are out of balance, nectar should fall but not, and vegetation will lose its vitality and wither if it is not nourished. Violent winds frequently strike, heavy rains occur from time to time, and the four seasons of heaven and earth are out of order, which deviates from the normal law, and will lead to the death of all things before they live half their lives. Only saints can adapt to the changes of nature and pay attention to health, so the body will not suffer from serious diseases. If everything can adapt to natural changes without losing the way of maintenance, then its vitality will not fail.
If it is contrary to the qi in spring, the qi of shaoyang will not produce hair, which will lead to the depression of liver qi and produce diseases. If it goes against the summer qi, the sun qi can't grow, which will lead to heart failure. If it is contrary to the convergence of autumn, the Taiyin qi will not converge, which will lead to lung qi irritability. If it goes against the latent qi in winter, the qi of shaoyin can't lurk, which will lead to the depression of kidney qi.
The change of yin and yang throughout the year is the foundation of life of all things. Therefore, saints maintain yang in spring and summer to meet the needs of growth; Maintain yin qi in autumn and winter to meet the needs of collection. Conforming to the fundamental law of life development, we can move and develop together with everything in the four-time cycle of germination, growth, convergence and closure. If you violate this law, it will destroy the essence of the human body and damage the body.
Therefore, the four seasons of yin and yang are not only the final starting point of the growth of all things, but also the source of life and death. If you violate it, disaster will happen; Comply with it, you will not be seriously ill, and only when you understand this truth can you be regarded as familiar with the way of keeping in good health.
For this way of keeping in good health, saints can earnestly pursue it, but fools often violate it. Comply with the changes of yin and yang in the four seasons, you can survive, and you will die if you violate it. Obey it, and the human body will be healthy; If you violate it, your body will get sick easily. If adaptation is turned into violation, which violates the changes of Yin and Yang in the four seasons, the body and the natural environment will be rejected.
Therefore, saints do not advocate waiting for treatment after illness, but emphasize prevention before illness. Just like controlling chaos, it is not to control it after it happens, but to prevent it before it happens. This is the truth here. If the disease is treated after it is formed, and the trouble is treated after it happens, it is just like digging a well when you are thirsty and casting weapons when you are on the battlefield. Isn't it too late?
