立为洪垆大鼎以炼真，内以养铅汞，外以象坎离，运其阴阳，驱龙驭虎，以返本还原，
于是玄霜绛雪、玉蕊金膏，九转而成宝矣。离发乎坎下，汞居乎水中，上下之象也。神
居其中，谓之三才。道生于一、一生二，二生三，三生万物，终始于一者也。一者水也，二者火也
，三者土也，水火者各得其一者也。得一者物之母，故水生一男为坎，名曰汞；火生二女为离
，名曰铅。谓之四象。汞，丹也。铅，药也。天老神君曰∶用铅不用铅，须向铅中作，及至用铅时，
用铅还是错。何言之？汞，阳也，子也；铅，阴也，母也。汞无铅则独子不母，何以生哉？铅汞合
而三年为宝，焚去铅之气，是为脱壳，其名曰纯阳（用铅不用铅也）。夫起火必于子，何也？承阳气
起火，火力斯全，过乎子则阴盛而火不然也。《经》曰∶火起于脐下，水出于鼎中，既济之象也。吾
有中宫之鼎在乎心之下（即规中）。是鼎也，时至卯则增铅（精也），时至酉则增汞（津也），铅不
得火则不腾，汞不得铅则不凝。《经》曰∶取水于山（脑也），起火于海（脐也），取汞于重楼，采
铅于九天。其运也备乎四时，与神御之，与气和之，于是四象具矣。而中宫之鼎状如鸡子，三年赤白
判而换躯矣。金肠玉骨出于五行，其名曰蜕，故四象交而汞干矣，一阳备而铅去矣，其名曰还丹。于
是神魂立矣，其体刚矣，三花合一，五彩归阳，夫是之谓无修之地。昔纯阳子问于正阳子曰∶何以谓
之铅与汞乎？答曰∶铅生于肾之左，外玄内白，水之正气也，居北方（子位也），阴中之阳也；汞生
肾之右，外青内赤，金之正气也，居南方（午位），阳中之阴也。问曰∶火与水在于身，何物为之乎？
曰∶下元真一之气，既极而成，火起于脐之下者也。水者，出于脑者也。火从下发如蒸釜焉，此既济
之道也。问曰∶铅者静也，性也；汞者动也，命也，果何所生？曰∶五谷之真气，为心所窃，化而为
血，血化为液，液复化为真气，凝而为神，此性也。命居于二肾之中，元海之内，所出真元之气，其中
有真水焉，本生于
心，流于肾，化而为精，精者莫亲于斯二者也。曰∶脾谓之黄婆何也？曰∶脾能接心之液、
肾之气，和合而成丹者也，故云黄婆。金液炼形，形神妙而合道真，何谓也？曰∶炼汞成
神，炼气成形，于是后生前咽，二物合而成胎，是谓与道合真，斯金液炼形者也。七返九
还何谓也？曰∶时自子而至申九转也，故炼者九年为一转，三转为一周，是故九炼而还丹
。一年益气，二年益血，三年益脉，四年益肉，五年益髓，六年益筋，七年益骨，八年益
发，九年益形。九者既成，其目点漆，其肤凝脂，其骨化玉，其肠化筋，白毫生于眉，金
光周于身，行轶六骥，洞视百步之外，口鼻常有清香之味内行五脏者，七窍也。吾之真气
上下周流，自申至于寅，七返也。一阴一阳，一升一降，一浮一沉，精也，髓也，涕也，唾
也，气也，液也，津也，昼夜存之而不走失者，七返也。采丹者何也？曰∶满口含津而搬
归于命府，运气于黄庭之中，于是气液造化而成精。津积为血，血积为珠，珠为汞，汞为砂
，砂为丹，此为采丹者也。三车何谓欤？曰∶前后微胁者，牛羊鹿车也。胃脘者，河车也，天
河也，水府真一之气从天内来，通于口鼻，故曰河车，脐之下者，火车也。曰∶二泉孰生乎
？曰∶其出于口之中，舌之下，左右有二穴，其大如针锋，通于心肺，时有津液生于咽，此润
万物而濡五脏者也。纯阳子既闻要道，于是发玄键而知八漏之禁也。目之泪走者，肝漏；
鼻之涕走者，肺漏；口之唾走者，肾漏；外肾之汗走者，心漏；夜而盗汗者，小肠漏；寝而有
涎者，脑漏；梦与鬼淫者，神漏∶淫欲者，身漏。是八者能固，使入于金鼎玉池，聚之以为铅汞。
其可度乎？能取津于玄膺，入于明堂，溉于喉下，有还丹则必上烹元液，使阴尽而阳生，
火抽而水添，循环而不止。何以取津乎？搅漱舌之下则波涛自满，咽之则注于丹海矣
。大功欲成者，其邪关外塞、命关中开乎？肺者，主乎荣卫二气，其在于肾是为金水相生
，父子之道也。行三十咽于玉池，则百脉通而血液滋矣，此七返者也。何云乎腾脑成
云、降口成水、传肺成唾、传心成血、传肝成精、传脾成液、传肾则成二脉而为阴精阳粹
者也？金津玉液者，阴阳之所生也。夫能上经七返，传入于二肾；下变九还，传至于
脑，上下往来而不息，则元气充实。八素之液流通其肾，受精贯于五内，更九九之真火，
气满候足，而金丹成矣。
行七转九还，则可以辟谷。舌下泉，此不饥之药也。即初学之士，但能闭目静坐，
终日不见一人，不饮不食，时以舌抵上 ，搅上下齿内外，取舌下泉满口即咽下，咽后又以
前法行之，愈行愈觉精神，每昼夜计行五百度，腹中自然不饥，其间觉有神明之通，
大丹之成，如在数日光景，快乐不可名状，此云休粮诀也。故曰∶华池神水，玉汞金铅。
乾坤运用，日月烹煎。屯蒙发火，进退精研。抽添沐浴，九转一年。坎浃离通，功行三千。
持之勿怠，化形为仙。
建立巨大的洪炉大鼎来修炼真元，内部用来涵养铅汞（指代人体内的精气神），外部象征坎离（八卦中的水与火），运转阴阳，驾驭龙虎（指代心神与肾气），以返回本源、还原先天状态，
于是玄霜绛雪、玉蕊金膏（比喻体内生成的珍贵精华），经过九次转化而成宝。离卦发源于坎卦之下，汞（代表心神/液）居于水中，这是上下对应的象。神居其中，称为三才（天、地、人）。道从“一”产生，“一”生“二”，“二”生“三”，“三”生万物，始终归于“一”。“一”是水，“二”是火，“三”是土，水火各自得到其一。“得其一”是万物的母亲，所以水生出一个男婴为坎卦，名叫汞；火生出两个女婴为离卦，名叫铅。这称为四象。汞，是丹；铅，是药。天老神君说：“用铅不用铅，必须在铅中做功夫，等到真正用铅时，只用铅还是错的。”为什么这么说？汞，属阳，是子；铅，属阴，是母。汞没有铅就像独子没有母亲，怎么能生长呢？铅和汞结合三年成为宝物，焚烧去除铅的浊气，这叫脱壳，其名称叫纯阳（这就是所谓的“用铅不用铅”）。起火必须从子时开始，为什么呢？承接阳气起火，火力才完全，过了子时则阴气盛而火不燃。《经》说：“火起于脐下，水出于鼎中”，这是既济卦（水火相交）的象。我心中有一个中宫之鼎位于心之下（即规中）。这个鼎，时间到卯时则增加铅（精），时间到酉时则增加汞（津），铅得不到火就不能升腾，汞得不到铅就不能凝结。《经》说：“取水于山（脑），起火于海（脐），取汞于重楼（气管），采铅于九天。”它的运行备具四季的变化，配合神的驾驭，配合气的调和，于是四象就具备了。而中宫之鼎形状像鸡蛋，三年后赤白分明并更换躯体。金肠玉骨出于五行，其名称叫蜕，所以四象交合而汞干涸了，一阳具备而铅去除了，其名称叫还丹。于是神魂确立，身体刚健，三花合一，五彩归阳，这就叫做无修之地。以前纯阳子问正阳子说：“什么叫铅和汞？”回答说：“铅生于肾之左，外黑内白，是水的正气，居于北方（子位），是阴中之阳；汞生于肾之右，外青内赤，是金的正气，居于南方（午位），是阳中之阴。”问：“火与水在身体里，什么东西构成它们呢？”答：“是下元的真一之气，极盛而成，火起于脐下。水，是从脑中出来的。火从下面升起像蒸锅一样，这是既济之道。”问：“铅是静，是性；汞是动，是命，究竟从哪里产生？”答：“五谷的真气，被心窃取，化为血，血化为液，液又化为真气，凝结而为神，这就是性。命居于两肾之中，元海之内，所出的真元之气，其中有真水，本来生于心，流于肾，化为精，精没有比这两者更亲近的了。”问：“脾为什么叫黄婆？”答：“脾能承接心的液、肾的气，和合而成丹，所以叫黄婆。金液炼形，形体与精神微妙地合于道真，这是什么意思？”答：“炼汞成神，炼气成形，于是后生前咽，两种物质结合而成胎，这叫与道合真，这就是金液炼形。”七返九还是什么意思？答：“时间从子时到申时共九转，所以修炼者九年为一转，三转为一周，因此九炼而成还丹。第一年益气，第二年益血，第三年益脉，第四年益肉，第五年益髓，第六年益筋，第七年益骨，第八年益发，第九年益形。九年成就后，眼睛如点漆，皮肤如凝脂，骨头化为玉，肠化为筋，白毫生于眉毛，金光环绕全身，行走超过六匹骏马，能洞察百步之外，口鼻常有清香的味道，内行五脏的是七窍。我的真气上下周流，从申时到寅时，这叫七返。一阴一阳，一升一降，一浮一沉，精、髓、涕、唾、气、液、津，昼夜保存而不走失，这叫七返。什么是采丹？答：“满口含津并将其搬归于命府，运气于黄庭之中，于是气液造化而成精。津积聚为血，血积聚为珠，珠为汞，汞为砂，砂为丹，这叫采丹。”什么是三车？答：“前后微胁处，是牛羊鹿车。胃脘处，是河车，也是天河，水府真一之气从天内来，通于口鼻，所以叫河车，脐下处，是火车。”问：“二泉是谁产生的？”答：“它出于口中舌下，左右有两个穴，大小如针尖，通于心肺，时常有津液生于咽喉，这是滋润万物并濡养五脏的东西。”纯阳子听了要道之后，于是打开玄键并知晓八漏的禁忌。眼泪流走，是肝漏；鼻涕流走，是肺漏；口水流走，是肾漏；外肾出汗流走，是心漏；夜间盗汗，是小肠漏；睡觉流涎，是脑漏；梦中与鬼淫，是神漏；淫欲，是身漏。这八种如果能固守，使它们进入金鼎玉池，聚集作为铅汞，这样可以度化吗？能从玄膺吸取津液，进入明堂，灌溉于喉下，有还丹则必然在上烹煮元液，使阴尽而阳生，抽火添水，循环不止。怎么吸取津液呢？搅漱舌下则波涛自满，咽下则注入丹海了。大功想成就的人，难道不是邪关外塞、命关中开吗？肺，主管荣卫二气，它在肾那里就是金水相生，是父子的道理。在玉池行三十咽，则百脉通而血液滋生了，这就是七返。为什么说上通脑成云、下降口成水、传肺成唾、传心成血、传肝成精、传脾成液、传肾则成二脉而为阴精阳粹呢？金津玉液，是阴阳所产生的。如果能上行经过七返，传入两肾；下行变为九还，传至于脑，上下往来不息，则元气充实。八素之液流通于肾，受精贯注于五脏，再经过九九真火的锻炼，气满候足，金丹就成功了。
行七转九还，就可以辟谷。舌下泉，这是不饥的药。即使是初学之士，只要能闭目静坐，整天不见一人，不饮不食，时常以舌抵上颚，搅动上下牙齿内外，取舌下泉满口就咽下，咽后又用前面的方法施行，越施行越觉得精神，每天每夜计算施行五百遍，腹中自然不饿，其间觉得有神明相通，大丹成就，好像在几天光景，快乐不可名状，这叫休粮诀。所以说：华池神水，玉汞金铅。乾坤运用，日月烹煎。屯蒙发火，进退精研。抽添沐浴，九转一年。坎浃离通，功行三千。持之勿怠，化形为仙。
Establish the great furnace and large tripod (Honglu Dading) to refine the true essence, internally nourishing Lead and Mercury (representing Jing and Shen), externally symbolizing Kan and Li (Water and Fire in Bagua), operating Yin and Yang, driving Dragon and Tiger (Shen and Kidney Qi), to return to the origin and restore the primordial state.
Thus, Xianshuang Jiangxue (Mysterious Frost and Crimson Snow), Yurui Jingu (Jade Stamen and Golden Paste), through nine transformations, become treasures.
Li (Fire) originates from below Kan (Water), Mercury resides in Water, representing the image of above and below.
Shen (Spirit) resides in the middle, called the Three Powers (Heaven, Earth, Human).
The Dao generates One, One generates Two, Two generates Three, Three generates all things, ultimately returning to One.
One is Water, Two is Fire, Three is Earth; Water and Fire each obtain their one.
Obtaining One is the mother of all things; thus, Water generates a male as Kan, named Mercury; Fire generates two females as Li, named Lead. This is called the Four Images.
Mercury is Dan (Elixir); Lead is Medicine.
Tianlao Shenjun said: "Use Lead but not Lead, must work within Lead; when it comes time to use Lead, using Lead is still wrong." What does this mean?
Mercury is Yang, the Son; Lead is Yin, the Mother.
Without Lead, Mercury is a son without a mother, how can it generate life?
Lead and Mercury combine for three years to become a treasure; burning away the turbid Qi of Lead is called shedding the shell, its name is Pure Yang (this is what is meant by "using Lead but not Lead").
Starting the fire must occur at Zi hour (11 PM - 1 AM), why? Because it inherits Yang Qi to start the fire, making the fire power complete; after Zi hour, Yin becomes dominant and the fire will not burn.
The Classic says: "Fire starts below the navel, Water emerges from the tripod," which is the image of Ji Ji (Water and Fire interacting).
I have a Central Palace Tripod located below the heart (i.e., Guizhong).
This tripod, when the time reaches Mao hour (5 AM - 7 AM), increases Lead (Jing/Essence); when the time reaches You hour (5 PM - 7 PM), increases Mercury (Jin/Yellow Fluid).
Lead cannot rise without Fire; Mercury cannot condense without Lead.
The Classic says: "Take Water from the Mountain (Brain), start Fire from the Sea (Navel), take Mercury from Chonglou (Throat/Trachea), gather Lead from Jiutian (Top of Head)."
Its operation prepares for the four seasons, guided by Shen and harmonized with Qi, so the Four Images are complete.
The Central Palace Tripod is shaped like an egg; after three years, Red and White separate and the body transforms.
Golden Intestines and Jade Bones emerge from the Five Elements, named Tuo (Molting); thus, when the Four Images intersect, Mercury dries up, and when One Yang is complete, Lead is removed, named Huan Dan (Returning Elixir).
Thus, Hun and Shen are established, the body becomes firm, Three Flowers unite, Five Colors return to Yang, this is called the Place of Non-Cultivation (Natural Attainment).
Previously, Chunyangzi asked Zhengyangzi: "Why are they called Lead and Mercury?"
Answered: "Lead is born on the left of the Kidneys, black outside and white inside, the righteous Qi of Water, residing in the North (Zi position), Yang within Yin; Mercury is born on the right of the Kidneys, green outside and red inside, the righteous Qi of Metal, residing in the South (Wu position), Yin within Yang."
Asked: "Fire and Water are in the body, what generates them?"
Answered: "The True One Qi of the Lower Yuan, when extreme, generates Fire starting below the navel."
Water comes from the brain.
Fire rises from below like a steamer, this is the Way of Ji Ji.
Asked: "Lead is static, representing Nature (Xing); Mercury is dynamic, representing Life (Ming), what do they actually come from?"
Answered: "The true Qi of the five grains is stolen by the Heart, transformed into Blood, Blood transforms into Fluid, Fluid transforms back into True Qi, condensing into Shen, this is Xing."
Ming resides in the center of the two Kidneys, within the Yuan Sea, the True Yuan Qi emitted from there contains True Water, originally born from the Heart, flowing to the Kidneys, transforming into Jing (Essence); Jing has nothing closer than these two.
Asked: "Why is the Spleen called Huangpo (Yellow Nanny)?"
Answered: "The Spleen can receive the fluid of the Heart and the Qi of the Kidneys, harmonizing them to form Dan, hence called Huangpo."
Jinye Lianxing (Golden Fluid Refining Form), where form and spirit subtly merge with the True Dao, what does this mean?
Answered: "Refining Mercury into Spirit, refining Qi into Form, then posterior generation and anterior swallowing, two substances combine to form a fetus, this is merging with the True Dao, this is Jinye Lianxing."
What is Qifan Jiuhuan (Seven Returns and Nine Restorations)?
Answered: "From Zi to Shen involves nine turns, so cultivators take nine years as one turn, three turns as one cycle, thus nine refinements yield the Returning Elixir."
First year benefits Qi, second year benefits Blood, third year benefits Vessels, fourth year benefits Flesh, fifth year benefits Marrow, sixth year benefits Tendons, seventh year benefits Bones, eighth year benefits Hair, ninth year benefits Form.
After nine completions, eyes are bright like lacquer, skin smooth like congealed fat, bones transform to jade, intestines transform to tendons, white hairs grow between eyebrows, golden light surrounds the body, walking surpasses six horses, seeing clearly beyond a hundred steps, mouth and nose often have a clear fragrance.
Internally circulating the Five Zang, externally connecting the Seven Orifices.
My True Qi circulates up and down, from Shen to Yin, this is Qifan (Seven Returns).
One Yin and One Yang, one ascending and one descending, one floating and one sinking, Jing, Marrow, Nasal Mucus, Saliva, Qi, Fluid, Jin, preserved day and night without loss, this is Qifan.
What is Caidan (Gathering Dan)?
Answered: "Fill the mouth with saliva and transport it to the Mingfu (Life Gate), move Qi to the Huangting (Yellow Court), thus Qi and Fluid create Essence. Saliva accumulates into Blood, Blood accumulates into Pearl, Pearl is Mercury, Mercury is Sand, Sand is Dan, this is Caidan."
What are the Three Vehicles?
Answered: "The areas slightly below the ribs front and back are the Ox, Sheep, and Deer vehicles. The epigastrium is the River Vehicle (Heche), also Tianhe, where True One Qi from the Water Mansion comes from within Heaven, passing through mouth and nose, hence called Heche; below the navel is the Train Vehicle (Huoche)."
Asked: "Who produces the Two Springs?"
Answered: "They emerge from the mouth, under the tongue, with two acupoints on left and right, size like needle tips, connecting to Heart and Lung, often producing saliva in the throat, this moistens all things and nourishes the Five Zang."
Having heard these essential teachings, Chunyangzi opened the mysterious lock and knew the prohibitions of the Eight Leaks.
Tears flowing out are Liver Leak; nasal mucus flowing out is Lung Leak; saliva flowing out is Kidney Leak; sweat from external genitals is Heart Leak; night sweats are Small Intestine Leak; drooling during sleep is Brain Leak; dreaming of sexual intercourse with spirits is Spirit Leak; lust is Body Leak.
If these eight can be secured, allowing them to enter the Golden Tripod and Jade Pool, gathering them as Lead and Mercury, can one be saved?
Can one extract saliva from Xuanying, enter Mingtang, irrigate below the throat, if there is Huan Dan, then necessarily cook Yuan Ye above, making Yin exhaust and Yang generate, drawing out Fire and adding Water, cycling endlessly.
How to extract saliva? Stir and rinse under the tongue, waves fill naturally, swallowing injects into the Dan Sea.
For those whose great work is about to succeed, is it not that the Evil Pass is sealed externally and the Life Pass opens internally?
The Lung governs Ying and Wei Qi; in the Kidney, it is Metal generating Water, the way of father and son.
Swallow thirty times in the Yu Chi (Jade Pool), then hundred vessels open and blood nourishes, this is Qifan.
Why say: Ascending to brain becomes Cloud, descending to mouth becomes Water, transmitting to Lung becomes Saliva, transmitting to Heart becomes Blood, transmitting to Liver becomes Essence, transmitting to Spleen becomes Fluid, transmitting to Kidney becomes Two Vessels forming Yin Essence and Yang Purity?
Jin Jin Yu Ye (Golden Saliva and Jade Fluid) are generated by Yin and Yang.
If one can ascend through Qifan, transmitting to two Kidneys; descend changing to Jiuhuan, transmitting to the Brain, going up and down ceaselessly, then Yuan Qi becomes full.
Ba Su fluids circulate in the Kidneys, fertilizing and penetrating the Five Internal Organs, further refined by Jiujiu True Fire, when Qi is full and timing sufficient, the Golden Dan is formed.
Practicing Qizhuan Jiuhuan allows Bigu (Grain Avoidance).
The Spring under the tongue is the medicine against hunger.
Even for beginners, if they can close eyes and sit quietly, seeing no one all day, drinking or eating nothing, often touching the upper palate with the tongue, stirring inside and outside of upper and lower teeth, taking the spring water under the tongue until the mouth is full, then swallowing, and repeating the previous method, the more practiced, the more spirited one feels. Counting five hundred repetitions per day and night, the abdomen naturally feels no hunger, among which one feels spiritual connection and the completion of the Great Dan, seeming like just a few days, happiness indescribable, this is called Xiuliang Jue (Grain Avoidance Formula).
Therefore it is said: Huachi Shenshui (Divine Water of the Splendid Pool), Yu Meng Jin Qian (Jade Mercury and Golden Lead).
Qiankun operates, Sun and Moon cook and fry.
Zhun Meng starts fire, advance and retreat carefully studied.
Chou Tian Mu Yu (Drawing and Adding, Bathing), nine turns in one year.
Kan penetrates, Li connects, merit performs three thousand.
Hold it without laziness, transform form into Immortal.
