Xiadantian is the base for the lifting, opening and closing of Qi, and also the place where men hide essence and women raise babies. Difficult Classics holds that Xia Dantian is "the ancestor of life, the source of anger, the root of internal organs, the root of the twelve meridians, the meeting of Yin and Yang, the door of breathing, and the hometown where fire and water meet." Therefore, qigong experts often regard the abdomen as the main part of exercising, gathering and storing the true qi. Human vitality comes from the kidney and is hidden in the abdomen. Through the triple energizer, it flows throughout the body and promotes the functional activities of the five internal organs. The strength of the human body, life and death, depends entirely on the rise and fall of Tian Chan's vitality. Therefore, health care experts attach great importance to maintaining the vitality of dantian. If Tian Dan is full of vitality, it can mobilize people's potential and make the true qi circulate throughout the body. By observing the abdomen, we can regulate yin and yang, communicate with the heart and kidney, replenish qi and dredge eight veins, restore innate physiological functions, and promote good health and longevity. It is thought that qi enters the lower abdomen along ren meridian, first with tongue buckling teeth, then with red dragon stirring water for three weeks, then with body fluid naturally entering the abdomen to guide qi, and then count the breath. Don't worry about where the qi goes in the abdomen, because the qi will eventually return to the abdomen. The method is to close your eyes gently and deliberately "look inward" at the navel along the tip of your nose, and practice for half an hour to an hour at a time. I practice in an upright position. I just started to learn kung fu, and I have no obvious feeling of staying in my abdomen. But my feet often itch, and I don't itch after work; Sometimes the palm of your hand is heavy, sometimes the whole person seems to be heavy, and unconsciously it becomes a standing pile form; Sometimes my legs will tremble ... the way to get my work is to gently press the position of my abdomen with both hands and palms, and repeatedly say in my mind: I want to get my work, I want to get my work, until my spirit returns to normal, just gently move my joints. After the feeling of heat appeared in the abdomen, many questions were solved: where is the abdomen? The place with a fever is Tian Dan. How to raise it? Keeping the feeling of abdominal warmth is intentional defense. What should I do next after Tian Dan has a fever? Still in the abdomen. This kind of "intentional defense" is not concentrated defense, but "seemingly defensive non-defensive", that is, it is enough to know clearly that there is a warm feeling in the abdomen. It is to keep a warm feeling, not to keep it in the position of the abdomen. People who reach this level of alchemy can stay in the abdomen anytime and anywhere. It is convenient for me to say this. Actually, I don't have to be serious. It is a natural perception, which is called "observing without observing". Practice course 1\2 Abide by the mystery of the lower abdomen. Simply put, it is to eliminate distractions and concentrate on the abdomen, without ears, eyes, nose and brain, and concentrate on the activities of qi. When practicing qigong, we should first pay attention to concentration and stick to the abdomen. The abdomen is in the middle of the lower abdomen, three inches below the navel, which is the source of our vitality. After adjusting breathing, breath movement pushes the true qi down and concentrates on the abdomen. If the qi in the abdomen is full, the Du meridian can be penetrated, and the so-called "accumulation of qi to rush through the customs" can enter the profound realm. The so-called intentional defense means indifference and concentration. Shouzi has a clear meaning in the book, that is, in Shangshu, it is "only refined and exclusive, tolerant of the middle"; The so-called "university" said: "Zhi Zhi will decide later, and then it can be quiet"; Buddhism says "stop at the view" and Mencius puts forward "seeking peace of mind", all of which refer to intentional defense. As the saying goes, "locking the heart and tying the horse" is also intentional. In the classic of internal work, it is more specific: "Thailand collapses in the front and does not move, and the tiger is stunned in the back." In Neijing Su Wen Gu Naive Theory, it is said: "Nothing is indifferent, and the true qi follows, and God hides inside and is ill." To keep God is to keep the belly. Confucius told Yan Yuan, "see no evil, don't listen to evil, don't say evil, don't move if you are evil.". These four no's are concrete measures for intentional defense. Just as the scripture says, "We are here to read, to interpret, and to say forever", it also points out the methods of intentional defense. The word Tian Dan originated from Taoism, but there is no distinction between Confucianism and Buddhism. According to the definition of Tian Dan, it is a magical medicine, the essence and efficient substance extracted from many drugs for fitness and disease. Therefore, it has been passed down from generation to generation as a "panacea", because it can cure diseases and prolong life, so the life motive force generated by physiological changes in the human body-Qi, is also called "Dan" by Taoists and physicians. The so-called "Dantian" is where Dan gathered. It is the most important part of the human body and the source of life force. According to the general literature, "Dantian" is located three inches below the umbilicus and on the median line of the lower abdomen, which is Renmai Guanyuan point. There are inferior epigastric arteries and veins behind the bladder and in front of the rectum, and there are 1 1 and 12 anterior cutaneous branches of intercostal nerves, which contain the small intestine in the deep part, and are acupoints for the small intestine meridian. It is the meeting of Sanyin and Renmai. Similar to a mezzanine room, it is the birthplace of Ren, Chong and Du. It is the place where the qi of the whole body meridians gathers, so it is also called "Qi Sea". Also known as Blood Room, Mingmen, Blood Sea, Sea, Uterus, Guanyuan, Xia Ji, Lu Jing, Darun, Dazhong and Dantian. "Dantian" is the place where men hide sperm and women conceive, from which human life is born, developed and grown, so it is also called birth gate and cell gate. Notes in Acupuncture Classic: It can treat leukorrhagia, infertility, lochia, hematuria, apoplexy, proctoptosis, stranguria, hernia, nocturnal emission, enuresis and fatigue. There is another saying: the Tianxin point between the eyebrows is Shangdantian. "Internal Classic" says: "The air sinks to the bottom of the sea, and the light gathers the heavenly heart." Because qigong has reached a considerable stage, light will be found between the eyebrows. There is also a saying that the acupoint of the mouth and heart is Zhongtiantian. Because of practicing qigong, we should pay attention to the spirit descending to the heart. At the Juque point, there is a sense of fever first. Juque point is also the point of heart meridian, which is mainly used for heartache, nausea, palpitation and forgetfulness. Neijing says, "Look at the heart palace and breathe into the sea." In acupuncture and moxibustion, there is also a theory that the Qi Hai point half an inch below the navel and the Shimen point two inches below the navel are Tian Dan. China Medical Dictionary points out that the abdomen is three inches below the navel. In the practice of qigong, I also realized that when the gas field sinks to three inches below the navel, it will be lively, round, reunion and rotation, and there will be endless vitality. Find Dantian quickly and recommend many people to practice Qigong or Wushu or something else. Some exercises to grasp when going to the abdomen.
