玉真先生说：无极中黄大道，原本是口传心授，不设立文字记录。我如今慈悲怜悯初学之士，一时听闻，不能记忆。所以设置这种善巧方便的方法，让他们入耳注心，眼观神领。传授度化结束后，立即焚毁此书，不要让它流散。内旨说：天有九宫，地有九州，人有九窍。天有中黄作为太阳，地有中黄作为太阴，人有中黄作为丹扃（丹田之门），都称为中黄。八极中言其位置，黄言其颜色，所以称为中黄。八极，是八方总会要处，也就是中宫，即黄庭（人体中心部位）、即玄牝（玄妙之牝门，指生命本源）、即先天一气、即玄关一窍、即至善之所、即黄极之道、即允执厥中（真诚地执守其中道）。在五行中称为土，在五脏中称为脾，在五常中称为信。药物、三气、五神、火候、呼吸，都在这里了。行住坐卧都应当注意意念，不可片刻离开。不废弃人事，但应当正心处物。常应常静。我的祖师所说的“多言数穷，不如守中”。又说：“三十辐共一毂。”辐者指胁肋，毂者指中扃。又说：“天地之间，其犹橐龠乎。”这是指呼吸。呼气则肾气上升，遇到土则停止。吸气则心液下降，遇到土则休息。这就叫水火锻炼而成大丹。如果能存守，则法无不灵验。我常说若要道法灵验，必须守中扃。中，是指理得上下四隅，不偏不倚的意思。天地相距八万四千里，人的心肾，就是一身的天地，相距八寸四分，以中指节纹为标准，从脐上至尻尾骨尖，长度八寸四分。现在说的脐，是与肾相对的位置。所以心之下去三寸六分，脐与肾之上三寸六分，只有中间一寸二分为黄庭，主宰我的身命，所谓至圣之道，秘之秘之。
三茅真君说：精养于气，气会于神。精神不散，这叫修真。子不离母，母不离子。子母持守，长生不死。洞真先生说：谨守谨守，莫言莫言，自然自然，玄之又玄。闻道之士，都是千生幸庆，宿有仙缘。如果借谈笑漏泄于人，会有不测之祸，蔓延之灾。受授之后，勤而行之。
玉溪真人说：儒家尧、舜、禹、汤、文、武、周公、孔子、颜回、曾参、思孟，历代道统相传，就是此道也。升（作者自称）少年仰慕清虚，留心至道。万法千门，无不师访。因游衡岳，才遇至人，密受紫阳仙翁丹诀。按九宫八卦，以年易月，以月易日，以日易时，取天地之正气，夺造化之奇功。纳归中宫，交感成丹。不仅延年，可以住世，所谓我命在我不由天。升自得之后，体力不衰，发鬓不白，日行百里，举动轻便。神异证验，不可具述。其间水火既济，又是坎离交会之法。久习行之，可以成丹。今之人盖火燥炎上，水湿润下，自勾引阴邪之气，乘间而入，令人多病。寿夭若遇，此诀使之。五行颠倒术，龙从火里出。五行不顺行，虎向水中生。顺行则凡，逆行则圣。玄之又玄，今悉于后。诀曰：一升便提，气气归脐；一降便咽，水火相见。这十六字，简而易行，不拘时候。或在官府，不妨政事；虽处富贵，不妨行用。所谓至道不繁也。如有风疾，见效甚速。但于日中少暇，或盘膝，或垂足、正坐，皆无所拘，取鼻中出入息为候。入息谓之吸，即便升气，将下部微力前提，其气尽归脐间，此之谓气气归脐。盖脐乃人之气海，所聚元气尽藏于兹。出息谓之呼，即便放身自在，一咽然有声，此谓之水火相见。如是行之，不计次数。要行且行，得止便止。若能久持，脐下常如火熨，腹中气响如雷，小便渐减，精气不泄，腰脊坚强，饮食倍进，百病去体，外邪不侵。行及一年，宿有诸疾尽除。行之既久，自然三宫升降，二气循环，遂成大道，长生久视也。昔年都下有过海王先生，教人行持，随鼻出入息升降之法，而不得提搐之法。次有恩州李道人，授杨和玉，只教提搐之法，而又不得出入息之法。皆用其偏枯。升因游南岳紫气峰下，亲受李先生秘诀。先生山东人也，一百五岁，发须不白，面如童颜，行步如飞。予得其传，行之既验。不敢自秘，谨以传好道之士。
Mr. Yuzhen said: The Great Dao of Wuji Zhonghuang was originally transmitted orally and mentally, without establishing written texts. Out of compassion for beginners who hear it once but cannot remember, I have now set up this skillful means to let them listen with their ears, focus their minds, observe with their eyes, and grasp with their spirits. After the transmission is complete, burn it immediately; do not let it circulate freely. The Inner Principle states: Heaven has Nine Palaces, Earth has Nine Provinces, and humans have Nine Orifices. In Heaven, Zhonghuang serves as the Solar Yang; in Earth, Zhonghuang serves as the Lunar Yin; in humans, Zhonghuang serves as Danjiong (the gate of the Dantian). All are called Zhonghuang. "Baji" refers to its position, and "Huang" refers to its color, hence the name Zhonghuang. Baji is the central gathering point of the eight directions, which is also the Central Palace, i.e., Huangting (the central cavity of the body), Xuanpin (the mysterious female, referring to the origin of life), Primordial Qi of Pre-Heaven, Xuanqiao One Aperture, the Place of Supreme Good, the Way of Huangji, and Yunzhi Juezhong (sincerely holding the Mean). In the Five Elements, it is called Earth; in the Five Zang Organs, it is called Spleen; in the Five Constants, it is called Trustworthiness. Medicinal substances, Three Qi, Five Spirits, Fire Timing, and respiration are all contained herein. Whether walking, standing, sitting, or lying down, one should maintain focused intention, never departing for a moment. One does not abandon worldly affairs but maintains a upright mind when dealing with things. Always responding yet always still. As my Patriarch said, "Speaking too much leads to exhaustion; it is better to guard the Center." It is also said, "Thirty spokes share one hub." The spokes refer to the costal arches, and the hub refers to Zhongjiong. It is also said, "Between Heaven and Earth, is it not like a bellows?" This refers to respiration. Exhaling causes Kidney Qi to rise and stop upon encountering Earth. Inhaling causes Heart Fluid to descend and rest upon encountering Earth. This is called the refining of Water and Fire to form the Great Elixir. If one can preserve and guard this, the methods will be effective. I often say that if one wishes the Dao methods to be efficacious, one must guard Zhongjiong. "Center" means aligning with the upper, lower, and four corners, neither biased nor leaning. Heaven and Earth are eighty-four thousand li apart. The human Heart and Kidneys represent the Heaven and Earth of the body, separated by eight cun four fen, measured by the creases of the middle finger joint, from above the umbilicus to the tip of the coccyx, measuring eight cun four fen. The term "umbilicus" here refers to the position opposite the Kidney. Thus, three cun six fen below the Heart, and three cun six fen above the Kidney at the umbilicus, only the middle one cun two fen constitutes the Huangting, which governs our life. This is the Supreme Sage's Dao, kept secret, kept secret.
The True Lord of Sanmao said: Essence nourishes Qi, and Qi converges into Shen (Spirit). When Spirit and Essence do not scatter, this is called cultivating the True. The child does not leave the mother, and the mother does not leave the child. Guarding the mother-child relationship ensures longevity and immortality. Mr. Dongzhen said: Guard carefully, guard carefully; speak not, speak not; natural, natural; profound and more profound. Those who hear the Dao are fortunate across a thousand lifetimes, having predestined affinities with immortality. If they leak secrets through laughter and talk, they invite unforeseen disasters and spreading calamities. After receiving the transmission, practice diligently.
True Person of Yuxi said: The Confucians Yao, Shun, Yu, Tang, Wen, Wu, the Duke of Zhou, Confucius, Yan Hui, Zeng Shen, Zisi, and Mencius passed down the lineage of the Dao through generations; this is precisely this Dao. Sheng (the author) admired purity and emptiness in his youth and devoted himself to the Supreme Dao. He visited ten thousand methods and a thousand schools, seeking teachers everywhere. While traveling Mount Heng, he finally met a Perfected Man and secretly received the Alchemical Secrets from Immortal Master Ziyang. Following the Nine Palaces and Eight Trigrams, exchanging years for months, months for days, and days for hours, he gathered the righteous Qi of Heaven and Earth and seized the miraculous achievements of creation. He stored them in the Central Palace, where interaction generates the Elixir. This not only extends life but allows one to remain in the world, saying, "My fate lies within me, not determined by Heaven." After attaining this, Sheng's physical strength did not decline, his hair and beard did not turn white, he could walk a hundred li a day, and his movements were light. His divine manifestations cannot be fully described. Among these, the mutual completion of Water and Fire is also the method of Kan-Li intersection. Practicing this for a long time can lead to the formation of the Elixir. Nowadays, people's Fire is dry and flares upward, while Water is moist and sinks downward, inadvertently attracting Yin-Evil Qi to enter opportunistically, causing many illnesses. Longevity or shortness of life depends on whether one encounters this secret. The Art of Reversing the Five Elements: Dragons emerge from Fire. If the Five Elements do not proceed normally, Tigers are born from Water. Proceeding normally makes one mortal; reversing makes one sage. Profound and more profound, all detailed below. The Secret says: Lift once it rises, Qi returns to the Umbilicus; Swallow once it descends, Water and Fire meet. These sixteen characters are simple and easy to practice, without restriction on time. Whether in government office, attending to political affairs; or in wealth and honor, practicing without hindrance. This is what is meant by the Supreme Dao being uncomplex. For wind diseases, the effect is very rapid. During leisure time in the day, whether sitting cross-legged, hanging feet, or sitting upright, there are no restrictions. Use the inhalation and exhalation through the nose as the indicator. Inhalation is called inhaling; immediately raise the Qi, using slight force from the lower part to lift it beforehand, so that all Qi returns to the umbilical area. This is called "Qi returning to the Umbilicus." The umbilicus is the Sea of Qi in humans, where primordial Qi gathers and hides. Exhalation is called exhaling; immediately relax the body freely, swallowing with a sound, which is called "Water and Fire meeting." Practice thus without counting repetitions. Practice when you wish, stop when you can. If maintained for a long time, the area below the umbilicus feels warm as if ironed, gas sounds in the abdomen like thunder, urination gradually decreases, essence and Qi are not leaked, the waist and spine become strong, food intake doubles, hundred diseases leave the body, and external evils do not invade. After one year of practice, chronic diseases are eliminated. With prolonged practice, the Three Palaces naturally ascend and descend, the Two Qi circulate, eventually forming the Great Dao, achieving longevity and clear vision. In past years, Mr. Wang Guohai in the capital taught the method of ascending and descending with nasal breath but lacked the lifting and drawing method. Later, Daoist Li from Enzhou taught Yang Heyu only the lifting and drawing method but lacked the breath method. Both used incomplete methods. Sheng, while visiting under Purple Qi Peak at Southern Mount Heng, personally received the secret from Mr. Li. Mr. Li was from Shandong, aged 105, with white-free hair and beard, face like a child's, walking swiftly. Having received his transmission, I found it effective after practice. Dare not keep it secret, I谨谨 transmit it to those who love the Dao.
