Health care is only the surface, and nourishing the heart is the essence of health care.

When asked about the way of keeping in good health, Wang Lao changed the subject: "I don't suggest you write too much about keeping in good health." Actually, I don't advocate health preservation. You can't just take tonics. I think it's more important to cultivate the mind. Speaking of Chinese medicine, a healthy person should be harmonious between yin and yang. Traditional Chinese medicine looks at the whole person. When you are uncomfortable, it is often not that' a certain part' is broken independently, but that the whole system is out of order. The biggest factor affecting the operation of the whole system is human emotions. "

"Being in a bad mood and depressed will lead to endocrine disorders in the body, which in turn will lead to multiple organ diseases. So in the final analysis, nourishing the heart and nourishing the nature is better than taking any tonic. "

How to raise your heart? Generally speaking, we should be calm, tolerant, not greedy for life, normal and natural.

If you are not greedy for life, you should not be afraid of death. Death is the law of nature. Everything in nature changes according to the laws of birth, growth, flowering, harvesting and hiding, while we humans follow the laws of birth, growth, strength, old age and death. In this process, we will relax and face this natural law calmly, and our mentality will naturally become peaceful.

Nature of law is the main philosophical thought of Taoism, and it is also the key to nourishing the heart.

Zhou Kai's understanding of Wang Lao's "observing nature" is: "We should be grateful for life and not be too demanding. Sometimes it doesn't matter if we can't reach our wishes. We can expect to get it in the next efforts, cherish the people and things around us, enjoy the present life, and find the fun of life at this stage at any stage. Money and fame are not the whole of life. If you are generous, nothing will make you sad and miserable.
