In traditional Chinese medicine, sitting and nourishing qi is also advocated by medicine. "Huangdi Neijing" said: "When there is no calm, its qi will follow; Mental memory, never getting sick? " Meditation is a method of concentrating attention and achieving the unity of body and mind, and it is a psychological suggestion therapy realized through meditation. In Harvard Medical School, doctors often teach patients how to meditate cross-legged to eliminate mental stress and troubles. In Japan, many young women also go to temples to meditate cross-legged to eliminate the pressure and troubles of work. The most important thing in meditation is to have a peaceful mind, so that we can calm down and settle down. This is a way for us to get to know ourselves again. When we feel happy, it is difficult to calm down, and vice versa. Meditation seems simple, but it is a very effective way to help you calm down.
