You first need to see how to understand the concept of "meditation". Buddhist meditation, Taoist meditation, medical care, Southern mindfulness, inward , Chinese meditation, meditation, Taoist sect casting and cultivating the essence; some spiritual practices, yoga, etc. have similar meditation practices. The requirements of each sect may not be unified.
Secondly, it depends on the purpose of meditation. Do you want to relax your body and mind, maintain mindfulness, or practice inner alchemy, be enlightened, or seek health, or even gain strange abilities? Different purposes and different time required.
Many various meditation materials on the Internet or in today's books also have no unified standards for this. Many answers, although the answers say one or two minutes, are fine for ten or twenty minutes, or even one or two hours, three or five hours, or even the longer the better. But I couldn't tell anyone that. The answer starting with
is based on the most traditional Chinese practice theory, and answered from the perspective of traditional Chinese medicine or Taoist medicine, because traditional Chinese medicine believes that the operation of qi and blood in the human body, body and body, and the changes in the natural climate are closely related. The human body and the qi and blood are qi and blood. The hand Taiyin lung meridian every day and night. It follows the yin twenty-five degrees and the yang twenty-five degrees. By the next day, the yin hour, the next day, the 50 degrees are circulated around the body, and then the Taiyin lung meridian of the hand Taiyin lung meridian is met.
The Yingwei Qi in a person is responsible for the operation of qi and blood. Every day, Yingqi circulates in the meridians, and the Wei Qi flows outside the meridians. The Yingwei Qi runs without a stop, and runs on the human body for fifty weeks in one day and night, and then meets once. It is equivalent to the Yingwei Qi running in the human body for one week every half hour. In addition to the entire meditation process, plus the time after meditation after meditation, it is almost 40 minutes, which is equivalent to letting the qi and blood run around the body. Due to the different operating times of Ying Qi and Wei Qi, " Ying Qi flows around the twelve meridians, each with 25 weeks of day and night. Wei Qi travels in Yang during the day and in Yin at night, and each with 25 weeks of night, and each with half of the day and night". Therefore, sitting in meditation once in the morning and evening is exactly in line with the running rules of Ying and Wei Qi, and walking around the body with qi and blood. Even if you cannot enter a state of static and calmness during meditation, it still has a good health effect.
As for the so-called qi of Ying and Wei, simply put,
"无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无无Nutrients are produced by the essence of water and grain. The qi of the qi is distributed in the blood vessels and operates throughout the body with the blood circulation.
"Haqi" refers to the function of defending the immune system and eliminating various foreign bodies endogenous to the body, including body barriers, phagocytosis system, humoral immunity , cellular immunity, etc.
is a supplement to knowledge. In " Huangdi Neijing·Lingshu ", there are related questions and answers about Huangdi . Huangdi asked Qibo and said :
"What qi is the qi? What qi is the wei? How can the wei be born? Where can the wei be met?"
Qibo answered: People receive qi from the wei, enter the stomach, and spread to the lungs. The five storages and six palaces are all used to receive qi. The clear one is the wei, and the turbid one is the wei. The Ying is in the meridian, and the Wei is outside the meridian. The Ying is endless, and the meeting is coming again at fifty. Yin and Yang are connected, like a ring without any reason. Wei Qi moves at the twenty-five degrees of Yin and at the twenty-five degrees of Yang. It is divided into day and night, so Qi rises at the yang and stops at the yin. Therefore, it is said: Yanglong is the middle of the day and the Double Ninth is the Double Ninth, and Yinlong is the Double Ninth in the middle of the night. Therefore, Taiyin is the main body of the inner body and the sun is the outer body. Each of them is twenty-five degrees, divided into day and night. In the middle of the night, it is Yin Long, and in the middle of the night, it is Yin Decline. In the morning, the Yin is over and the Yang is affected. In the middle of the day, Yang Long is over and the Yang is weak. In the west, the Yang is over and the Yang is over and the Yin is affected. At midnight, all the people lie down, and they are called "Merry Yin". On the same day, the Yin is over and the Yang receives the energy. This is the same as the heaven and earth.
