Meditation is the most important thing, and the heart likes quietness. Therefore, all previous generations of health care scientists regarded abstinence and the spirit of nourishing the heart as the main contents of nourishing the heart. "Su Wen, Pathogenesis, Qi and Life-saving Collection" says: "If God uses more, he will work hard, hide in his heart and be quiet." The so-called "quietness hides the spirit" and "quietness nourishes the spirit" means that the spirit is quiet, not delusional, and it is also necessary to prevent excessive use of the spirit.

Huangdi Neijing said, "Quiet means God hides, manic means God dies", and quiet means Yin. Only through Yin He's cooperation can people's hearts be maintained. Emotion is the master of the whole body. People have worldly desires, that is, joy, anger, worry, thinking, sadness, fear and surprise. When something happens, the seven emotions are out of balance and the mind is out of harmony. You should know that excessive happiness hurts the liver, excessive worry hurts the lungs, excessive thinking hurts the spleen, and excessive fear hurts the kidney. If a person thinks about the past all day and has more than one desire, there will be many diseases. It is not an exaggeration to say that bad mood is the catalyst of disease. One of the important ways to eliminate bad emotions is to learn to meditate. Only when you are calm can you be healthy and healthy can you exercise. The best way to meditate is to cultivate the mind, and the highest realm of meditation is music. Quiet means that people can be quiet alone in a complex world.

Silence is a state of mind. For example, Lao Tzu said, "Be empty and be quiet." It refers to the natural peace that is not troubled by fame and fortune, which helps to maintain an air of self-restraint. On the contrary, overwork and restlessness, seduced by fame and fortune, often easily consume people's vitality. Therefore, peace of mind is bright, peace of mind is quiet, guilty conscience is floating, and peace of mind is perfect, which is conducive to good health. When the external environment and the inner world can be quiet and comfortable, you can nourish your heart, be calm and feel safe. Quiet can control anger, quiet can eliminate troubles, and quiet can calm your mind. Neijing said: "Nothing is indifferent, the true qi will follow, the spirit will be hidden inside, and the disease will be safe." Peace is ideological stability; Nihility refers to the absence of distractions, anger, worry and panic. This sentence tells people that if the spirit is stable and quiet, there is no greed or delusion, then there will be true qi, and the spirit will be hidden inside, free from the interference of external pathogens, without emotional fluctuations inside the body, coordinated and unified between the human body and the external environment, and the true qi in the body is harmonious and harmless, and the spirit is sufficient, so diseases and pathogens will not invade the human body and people will not get sick.

Nourishing the heart lies in nourishing the spirit. Buddhists have something to say. There are three treasures in the sky, three treasures in the earth, three treasures in fire, three treasures in water and three treasures in people. Among the three treasures of human beings, essence should be turned into qi, and qi should be turned into god; God is the sum of essence, and God is human soul. Therefore, the cultivation of mind, meditation and joy will ultimately come down to spiritual cultivation. God's coagulation can calm the spirit, and the spirit can calm the heart. Conditioning the spirit, in the final analysis, is to purify the human soul. If your soul is always beautiful, then you have the medicine of youth.
