This is a very practical problem and deserves special attention. Generally, people who study "meditation" and "cultivation" read some books such as Xi Jing and Single Crystal, and often interpret the meaning according to the script, without real experience, or because of preconceived subjective imagination. They believe that the opening of Ren meridian must be connected with the above-mentioned Du meridian and guided by the same intention to enter Ren meridian. If it is an effort to "guide" with consciousness, it is not too much to imagine. If "meditation" is taken as an introduction to monasticism, it is superficial and inexpensive. Now, in order to explain the situation of "Ren Mai" of Qi Meridian, we will use the method of decomposition narration to let scholars understand it themselves. The center of Ren meridian lies in the middle palace: the so-called "middle palace" in Taoist books and China medicine is just an abstract name. Its main organ is the upper abdominal cavity, which can also be said to be the "stomach" part. Take the abstract concept of Yin-Yang Eight Diagrams as an example, it is the "earth house" of the five elements (water, fire, wood, gold and earth). During the Jin and Yuan Dynasties, there were two schools of TCM views on the key points of health preservation: (1) mainly treating stomach qi in the middle uterus. (2) Nourishing kidney and "stopping water" is the main method. This concept belongs to the theory of traditional Chinese medicine and is put aside for the time being. Their initial ideas are all derived from the logic of abstract concepts such as yin and yang gossip. The so-called "four images and five elements are all based on soil, and the nine palaces and eight diagrams are inseparable." Is the basis of these theories. But according to the truth, regulating the spleen and stomach is very important for a person's health, longevity, health preservation and cultivation. No matter what disease happens, the first serious warning is that the appetite of the stomach will go wrong first. For example, people who catch a cold must have a bad appetite and stomach problems. In other words, people with good digestion don't care even if they have a cold. Appetite leads to the esophageal tube, which is the so-called "twelve constructions" of Taoism, leads to the large intestine and has a common effect on the kidney and gonads. The gas in my stomach is rolling after sitting quietly, even the gas is humming, and I feel there is a bubble sound inside. This is the first sign. After this symptom, people tend to overeat, or feel full of gas and don't want to eat. If you overeat, you must control your diet and don't overeat because of your appetite. But at this time, we must pay attention to good nutrition and let it really absorb and melt. If you are full and don't want to eat, you should stop eating as appropriate. When you have an appetite, eat less and eat more slowly to replenish your body. Secondly, when the initial symptoms occur in the stomach of the above-mentioned "middle uterus", it is likely that snoring, burping and farting will occur at the same time. Some scholars, after reading the classic of Dan Tao or listening to the master's prescription, think that farting is a matter of venting "qi"; Try very hard to hold Gu Dao, hold the fart tightly, which makes the internal organs steaming. As for sallow and emaciated, it may cause constipation, internal hemorrhoids, external hemorrhoids and even other visceral diseases. In fact, it is true that a person's vitality cannot be leaked. In this process, it is not fart, but it makes sense. Let's talk about it later. In short, in this process, you can let it go freely, so that your stomach can be really cleaned up. There are two phenomena that deserve special attention: (1) It seems that people with severe stomach problems have a long, well, long breath. (2) Frequent defecation, some serious to diarrhea, even ten days and a half. Understanding of "playing for a long time" and "playing for a long time": this is a sign that stomach qi goes up (that is, it is the so-called qi-raising start like yoga gas refining), which will flush the esophageal tube. When the gas in the esophageal tube is really washed away, the mind will be fresh and comfortable. Moreover, the sweet and cool body fluids flowing from the top of the head to the "salivary glands" are slippery and self-contained and constantly fill the mouth. This is a sign that fairy wine and nectar are sprinkled in the books of Dan Dao, and it is also useful to use the wonderful term "nectar from jade liquid" as a metaphor. When I was studying tantric teachings in Kangzang area before, people with such a long, well, long breath would have a heart of reverence and worship, and were considered as extraordinary people with considerable achievements in pulse condition. The understanding of defecation frequency is similar to diarrhea: if an ordinary person defecates frequently, even diarrhea and watery stools, of course, he has serious gastrointestinal diseases or acute enteritis. But no matter what kind of symptoms, there is no doubt that it gives people a feeling of pain. If it is because of "sitting" to start the Qi-moving machine, although there are heavy diarrhea or drowning, there is no feeling of pain, and the mind and internal organs have a fresh and comfortable feeling. Although there is a slight sense of powerlessness, it is not a big problem. At the end of diarrhea, some slightly purple-black mucus will be produced, which is the performance of gastrointestinal stagnation. If it is really eliminated, diarrhea will naturally stop. If you are a person who specializes in health preservation and monasticism, after this stage, your mental state and physical feelings will definitely enter another new situation. However, when eating, we must be timely and appropriate, especially careful, and we must not be too full or eat indiscriminately. It is always wise to keep calm. Especially for sexual behavior between men and women, it is more important to observe the precepts. If you have a family, it is difficult to avoid customs, at least you should take "lust" as the best policy, if you violate the above warnings about men and women's diet; Need to experience "sitting" time-the accumulation of time, diarrhea and other phenomena happen again. This is also one of the important keys in the process of "sit-in" and "repeated defeats and repeated wars". As for those who indulge in immorality, it is even more important. Gastric Qi Activation in the Uterus and Esophageal Tube: Everyone knows our physiology. Starting from the throat, it is divided into two branches: esophagus (posterior) and trachea (anterior). If there is a disease in the tracheal system, or if you have a cold, cough and choking will occur. Take cough as an example. There is a difference between dry cough and phlegm cough. Dry cough is mostly caused by bronchitis. But some phlegm cough is related to the symptoms of esophageal tube and stomach. But for the "meditation" monks, when the "Zhonggong" qi machine is started, they will feel something blocked between the chest and diaphragm, and they want to vomit quickly but they can't vomit well. When the ascending qi is full, the sudden cough with thick phlegm is a sign of the initial opening of the esophageal tube. Taoist school, the name of this part, is called "Twelfth Floor". The tantric stream, the name of this part, makes the pulse knot known as the "benefit wheel" (throat wheel). In fact, it refers to the system that starts from the larynx and goes straight to the appetite area with the esophageal tube. Tantric practitioners believe that by opening the "throat chakra", you can be carefree. In fact, this is also a general statement. After really getting through the pulse of the "throat chakra" part, you can reduce the troubles of ignorance; In other words, unlike ordinary people who are emotionally agitated because of anxiety, it is not completely impossible to achieve delusion, but at least it can alleviate ignorance and delusion. Because it is completely impossible to be born without thoughts, it depends on psychological peace, not just physical function. So is the esophageal tube so important for physical and mental health? This is indeed a very important matter. Because the average person's esophageal tube is the main channel for transporting food frequently, although food is sent to the stomach for digestion through this channel, some food residues will still stagnate on the wall of the esophageal tube. If it is not cleaned for a long time, it will act as an antirust obstacle like an oil pipe or a water pipe, so it will also cause diseases such as esophageal cancer. For example, brewing a glass of milk with a glass, in any case, some fine ingredients of milk will remain on the glass wall. As for other food residues, it is easier to leave traces. Although physiological instinct has the function of automatic removal, it is difficult to completely disappear for a while. People who practice fitness yoga often swallow a long gauze to bring gastric lavage and esophageal tube, which is the reason. If the esophageal tube can be opened by the stomach qi of the "middle palace", the practice method of fitness yoga is very rude. Regarding the Taoist theory of "bird bridge", the tongue touches the upper jaw: the stomach gas goes up, the esophageal tube is opened, and the "middle" part of the chest will naturally feel suddenly enlightened. Even extremely quiet people can feel it-when they hear the heart, there seems to be a splitting and cracking sound, just like the feeling of "opening the heart" described by Buddhists. At this time, if something sinks, gas enters the lower abdomen, and the natural reaction of the tip of the tongue is tilted up. Regardless of Buddhism, Taoism, tantra, yoga, etc. One of the basic meditation methods is that the tongue touches the palate. Generally speaking, the tongue is pressed against the upper jaw to connect the saliva between the two teeth of the upper incisors; Absorb the new body fluid (a kind of endocrine) radiated by pituitary gland, and take "swallowing body fluid and inhaling" as the practice time of "rejuvenation". Therefore, it is natural for beginners to meditate as long as their tongue is against the palate, and it is necessary to swallow when the body fluid is full. What's more, body fluids sometimes have a sweet, faint and fragrant taste, which is unprecedented. However, when the stomach gas goes up through the esophageal tube, the Adam's apple naturally retracts and presses down, and the tip of the tongue naturally tilts up, vertically contacts with the small tongue part, and curls up to seal the larynx, so that the breathing gas naturally turns from a slight cough to a near-stop state. This situation is the phenomenon of climbing a ladder by driving a "bird bridge" as mentioned by Taoist single crystal. In the meditation method of yoga, this is a real effort to automatically "bottle gas" and stop breathing. In this way, the phenomena of "natural sound" and abnormal vibration sound caused by the vibration of the posterior cranial nerve, that is, the so-called "vulture sound behind the head" and "cash light in the eyes", naturally become clearer and clearer, and the state of peace of mind becomes clearer and clearer. Even so, it is worthy of special attention whether the qi descending from the stomach meridian of the "middle palace" really enters the lower abdomen (the inner center of the lower abdomen). If you were a monk when you were a child, this problem is another matter. It is not so simple for people who have had sexual behavior or disguised sexual experience (such as masturbation, wet dream, etc.). ) to be really angry. Because when the current qi will pass through the Dantian Qi Sea, the nerves above the small face and pubic bone will naturally feel tingling. When this tingling sensation is completely over, qi moves directly to the "seabed" prostate and penetrates into the genitals (women only go to the uterus). With a little attention, it will naturally contract and rotate. The prostate and even the perineum will naturally contract, and the abdomen (lower abdomen) will be full, resulting in internal breathing (referring to the phenomenon of slight breathing on the inside of the lower abdomen), which is what the single crystal Taoist called the "lower magpie bridge". Then the mouth and nose breathing and internal breathing are completely still, the genitals contract and the testicles tighten, just like the baby is not born. This is the initial phenomenon of "horse hidden phase" mentioned by the chief Taoist single crystal. At this point, it doesn't matter if you don't have enough to eat, which can really prove the initial efforts of "sitting still and waiting for death". However, the gap has really opened up the two veins of "Ren" and "Du"; There is still a long way to go to maintain harmony with Buddhism and transcend the realm of harmony between man and nature. As mentioned earlier, after the Qi is activated in the process of meditation, the second pulse of Ren Du reacts, and it is not even the real opening of Ren Du. However, most people regard these reactions as a phenomenon for the governor to get through, which is really "infatuation" and is suspected of crazy medical treatment. But it is only for health and longevity. If it is used properly, it is not without supplement. If you really want to learn Taoism, you should be careful and take a clear-cut stand, and don't admit that you have done something wrong. As mentioned earlier, when stomach qi starts the above-mentioned esophageal tube, there will be belching and snoring, which has caused some curious friends who have been sitting still to write to ask you about belching and snoring. Is that so? Suddenly it's hard to answer. In short, there is no doubt that both the belching cough caused by sedentary and the cough caused by stomach diseases are related to the gas in the stomach. Both Chinese medicine and western medicine have methods of drug regulation and neutralization of gastrointestinal waste gas. It is absolutely beneficial and harmless to practice meditation by seeking medical advice and giving medical help. In particular, people who practice Taoism attach great importance to the role of external medicine in assisting the progress of monasticism, so the reason why people who study Taoism can't help but be ignorant of medicine is also.
