一开臂，二开胸，三搅车，四挽弓。青霞翁《丹经直指》∶
仆自幼学道，弱冠弃家，遍历江湖，求师问友。得先师张悟真以来，诸前烈丹经、诗词、传记，
熟读精思，寻友求义。又尝遍参道友术士，访名山洞天，祷求石碑壁记，得海琼仙指迷大道之要。后
遇率然居士于朱陵洞天，作诗章以相赠，始得证海琼之妙旨。乃知年少所学、所求、所见，已是
屋上架屋，枝上接枝，殊不知屋便是屋，枝便是枝，道在迩而求诸远也。一但顿悟，切恐湮没无传；且
念后之学人，未必如此肯心留意。因录数语，以贻后人。得之者可因文解意，猛省用功，虽不求师，而
在其中矣。夫男子四大，一身皆阴。惟先天一气真阳，此气非吹、嘘、呼、吸之气，亦无形影气象可见。
故悟真先生以为可见不可用，可用不可见也。然此气未受形之先，在父母胎中，先受此气，然后生二肾，
便生二眼，由此生心、生肝、生脾、生肺、生九窍四肢而后人象俱足也。此气只在两肾中间，名为玄牝
之门。先师玄牝歌言之详，世间人莫能悟之。今人宰牲杀猪，但见两肾中间、腰脊去处有一空，膜中有此，
呼吸膨动，直至肉冷方息是也。此气未死之先，气血全盛，魂魄相属，内含五采，受气如汤。人一死则
如牲畜，气血一散而气馁矣。只此一气，便是金丹大药。故先师以肝、心、脾、肺、胆、肾、肠、精、津
液、涕唾、气血为非道，又以精神、魂魄意似是非者，此也。人之一身，右足大阴，左足太阳。而
足为涌泉，发水火二气，自双足入尾闾，上合于二肾。左为
肾堂，右为精府，一水一火，一龟一蛇，互相囊龠。二肾之间，虚生一窍，是为玄牝。二肾之气，贯
通玄牝之间，由此发黄赤二道。上夹脊双开，贯二十四椎，中通心腹入膏肓之下，会于风府，上朝泥丸。
由泥丸而下明堂，散灌五宫，下入重楼玉阙，直注于绛宫，复流入于本府。日夜循环，周流不息。皆
是自然而然，即不是动手脚做成的。今人流入旁门者，不知虚无自然默默运用之理，却乃妄行屈伸、
呵咽、摩擦、引导、存思、注视，妄想妄作，反致成疾。如白莲道人多黄肿，运气道人多气蛊，皆其验
也。夫此一气，人人一般，即无多少，但有涵养的做得成，无涵养的做不成。其流行出入，自有定数。
如海中潮候，弦朔必应天上，斗柄子午自移。又若女子月经，因时而至，确然不差。此气遇阳时为火，阴
时为水。火即木液，水即金精。又左肾为坎，右肾为离，离中有己，坎中有戊。以戊己二土合为圭字。
又名水中金，金者，刀也，故名刀圭。又火即木，水即金。为金木无间，水火同乡。其实金木水火只是
一土，一土为总五行尔。先师以为五脏无气，六腑无精，故谓此也。此气自然时时运转，不假人力。
凡言辘轳、三车、黄河、曹溪，取象如此，非以人力强为也。此气常以子时而至，为阳火。午时而至，
为阴水。以卯时而至，为木液。酉时而至，为金精。卯中有甲，酉中有庚。故须采取用甲庚。子中有戊，
午中有己，故运中土。自非洞晓乾坤升降、阴阳盛衰、药材老嫩、水火潜亢之理，不足以语此。然先师言
之甚详，而后人甚惑；言之愈多，而后人愈疑者，何也？皆缘终于虚无，无则不知下手功夫，是以
胎息不成而归于顽空。忽于自然，溺于妄想强作，是以心神枉费而返致疾。夫虚无者，言其不可见闻。
自然者，言其不
可以迎取。今之采取火候等逐节工夫，深浅之言，句句分明，节节谨切。谨守奉行，无不应验。凡未入
室以前，且理会，得安鼎采药。每日夜，且习打坐，坐一定然，则骨节关开，脉通自膀胱至夹脊，便如车
轮运动。先天一气，自然由三关朝泥丸，下重楼，入绛宫。然其来有时而采亦有时，须得甲庚金木旺
相之时，默默端坐，不须用摩动。须臾觉顶中火热，喉中甘露垂垂滴而下，便以目内视，一意以内送纳
之绛宫玄牝而止。凡一日之间，以甲应上弦，庚应下弦。自子至卯为上弦，得汞半斤；自午至酉为
下弦，得铅半斤。采甲汞庚铅各半斤，自然定数。所谓铅见癸生须急采者，言木汞金铅以甲庚二时采取
也。如此采取之法。然初采之时，不计年月，久久积之，方成鼎炉。夫一身，炉也。绛宫，鼎也。今
人以脾中黄庭、顶中泥丸为鼎，皆非也。年月既久，炉鼎方成。然后种药，药物一生，且采且炼。
采而积之为药，炼而成之为火。采之一日有一斤数，炼之一日有铢之得。采药之时，须采甲庚旺气。行
火之法则，忌甲庚沐浴，有此不同云。采之法，亦如鼎，然不过目，其自然之来.迎之以意，送之以目。
故丹书有黄婆、青女之说。黄婆，意也。青女，眼也。以意迎逢，谓之黄婆媒合；以目内送，谓
之青女传言。人身之气，随意而动。意行即行，意止即止。故送入鼎中，随意即止。不复下流矣。谓
之种药。药既入鼎，然后有火候焉。圣人传药不传火，以火与药同归殊途，同情异功故尔。子为一阳，至
巳为六阳。自子至巳，火得六数，而六阳成干。当其子至巳，以意迎之，谓之进火，谓之添。午为
一阴，至亥为六阴。自午至亥，水得六数，而六阴成坤。当其午至亥，以意送之，谓之退火，谓之抽。
故子巳为火，午亥为水。言火不言水者，
添进为火，抽退为水耳。自然而然，不假人为。丹经言河图洛书之有数者，言其火候自然，与此生
成之数合也，非必待用力而合此数也。言朝屯暮蒙，昼 夜复。亦言与卦默合，非必用力而方合此卦
爻也。如运用之说，则言此气营运流灌五脏百脉。如亥子旺肾，寅卯旺肝，巳午旺心，申酉旺肺，辰
戌丑未旺脾。自然此气营运，由旺宫而出。亦不必妄想此时此脏有气出入流运。然采取造鼎之初，则
无禁忌。时至即为，既了即了。至如入药行火，则须择日入室。一毫俗事，不可妄干。使耳目鼻口，
四象相忘，胸中淡然，虚室生白，一有所着便是封固不密，药物走漏，便非道也。既居室内，惟半
饥半饱，不可求睡。每使胸次惺然，常常提醒。见药即采，遇火即行。一年之内，止除卯酉二月不行水
火。以其卯则木旺，酉则金旺，木旺则火旺，金旺则水旺故耳。凡此二月不行水火者，盖行则返过而
伤也。一年十二月内，除卯酉二月外，止存十月。故十月而胎成，过十月又不须行火，则又谓之伤丹，
此谓火候。十月胎成，移入泥丸，谓之换鼎。此胎气既足，如人已生，但须乳哺。故换鼎入泥丸，乳
哺之谓。此时不须工夫火候，亦无沐浴，但只常常温养之。如此三年九载，则天门自开，婴儿自然出
矣，往来无碍而位登仙翁矣。此首尾用工之说，皆出自然，不假人力强为妄想，不过及时以意迎之
而已。此是积日累月，造鼎安炉。一年十月，结胎行火，先师以为一日金丹赫赫红是也。又谓顷刻可
成者，何也？言一时半日之工夫，可夺一年半纪之造化。当其药生之时，不过顷刻迎逢，谓之顷刻
金丹。即非终日终夜，劳神苦思，强为之也。夫药、炉鼎、火候、沐浴、胎息、婴儿、运用、抽添、
主宾、浮沉、升降、铅汞、水火、真土、金精、木液，一切
言说，皆是假名换姓，其实只为一物。钩锁连环，自可熟论见义。其有用工下手虚无自然之说，
先师许多丹经词诀尽矣。参同吻合，一以贯之，不过如此而已。然言之非艰，行之为艰，行之亦
非艰，守之为艰。何以守之为艰？大抵旁门小法，具无报应。惟金丹一件，便有报应。今人采药，
年少者，须半年功夫，守斋戒、沐浴、绝欲、忘念、静坐，默取采之。候时节到来，耳目手足轻

One, open the arms; two, open the chest; three, stir the cart (referring to the internal circulation of Qi like a wheel); four, draw the bow. Qingxia Weng in *Dan Jing Zhi Zhi* (Direct Guidance to Alchemical Classics) says:
I learned the Dao since childhood, left home at twenty, traveled the rivers and lakes, seeking masters and friends. After receiving guidance from my former master Zhang Wuzhen (Zhang Boduan), I studied the alchemical classics, poems, and biographies of previous alchemists, reading them thoroughly and thinking deeply, seeking friends to explore their meanings. I also widely visited fellow practitioners and scholars, explored famous mountains and grotto-heavens, prayed for stone inscriptions and wall records, and received the essential guidance of the Great Dao from Haiqiong Immortal (Bai Yuchan). Later, meeting Ranyan Jushi in Zhuling Grotto-Heaven, who gifted me poems, I was able to verify the profound principles of Haiqiong. Thus, I realized that what I had learned, sought, and seen in my youth was merely "a house built upon a house, branches attached to branches" (metaphorically redundant and deviating from the root), not knowing that the house is the house, the branch is the branch, and the Dao is near yet sought far away. Upon sudden enlightenment, I feared this Dao would be lost and forgotten; considering future students might not be so diligent, I recorded these few words to leave for posterity. Those who receive it can understand the meaning through the text, awaken suddenly, and practice diligently; even without a master, the principle is contained within. The four great elements (Earth, Water, Fire, Wind) constitute the male body, which is entirely Yin. Only the Primordial One Qi, True Yang, exists. This Qi is not the breath of blowing, sighing, calling, or inhaling/exhaling, nor does it have form, shadow, or visible phenomena. Therefore, Master Wuzhen believed that what is visible cannot be used, and what can be used is invisible. However, before receiving form, in the parents' womb, this Qi is received first, then the two kidneys are born, followed by the two eyes, then the heart, liver, spleen, lungs, nine orifices, and four limbs, until the human form is complete. This Qi resides only between the two kidneys, named the Gate of Xuanpin (Mysterious Female). My former master detailed this in *Xuanpin Ge*, but worldly people fail to comprehend it. When slaughtering animals today, one sees an empty cavity between the two kidneys and the spine; within the membrane, this Qi breathes, expands, and pulses until the meat cools. Before death, with full Qi and blood, soul and spirit united, containing five colors, the Qi flows like hot water. Upon death, like livestock, once Qi and blood scatter, the Qi dissipates. This single Qi is the Great Medicine of the Golden Elixir. Thus, my former master considered the liver, heart, spleen, lungs, gallbladder, kidneys, intestines, essence, fluids, tears, saliva, Qi, and blood as non-Dao, and similarly regarded spirit, soul, and intention as questionable, due to this reason. In the human body, the right foot is Taiyin, the left foot is Taiyang. Yongquan acupoint generates Water and Fire Qi, entering the Tailbone (Weilu) from both feet, ascending to unite with the two kidneys. The left is the Kidney Hall, the right is the Essence Mansion, one Water and one Fire, one Turtle and one Snake, mutually enclosing like bellows. Between the two kidneys, a void aperture is generated, which is Xuanpin. The Qi of the two kidneys penetrates through Xuanpin, giving rise to yellow and red pathways. Opening on both sides of the spine, they penetrate the twenty-four vertebrae, pass through the heart and abdomen into the lower Gaohuang, converge at Fengfu acupoint, and ascend to the Niwan Palace. From Niwan, descending to Mingtang, scattering and irrigating the Five Palaces, descending into the Chonglou Jade Gate, directly pouring into the Jianggong, and flowing back to the original mansion. Circulating day and night, unceasingly. This is all natural, not achieved by moving hands and feet. Those who stray into heterodox schools do not understand the principle of silent application in emptiness and nature; instead, they perform forced flexion and extension, hissing and swallowing, rubbing, guiding, visualization, and staring, leading to delusion and illness, resulting in diseases such as jaundice in White Lotus practitioners or abdominal distension in Qi-moving practitioners, which are verifications. This Qi is the same in everyone, with no difference in quantity; those with cultivation succeed, those without fail. Its flow and exit have fixed numbers. Like tides in the sea, responding to the moon's phases, or the Big Dipper shifting positions. Like a woman's menstruation, arriving on time without error. This Qi becomes Fire when encountering Yang, and Water when encountering Yin. Fire is Wood Liquid, Water is Metal Essence. The left kidney is Kan trigram, the right kidney is Li trigram; Li contains Ji Earth, Kan contains Wu Earth. Combining Wu and Ji Earth forms the character Gui. Also called Metal in Water; Metal means knife, hence named Dao Gui (Knife Measure). Fire is Wood, Water is Metal. Metal and Wood are inseparable, Water and Fire share the same home. Actually, Metal, Wood, Water, and Fire are just one Earth; Earth encompasses the Five Elements. My former master said the Five Zang organs lack Qi, and the Six Fu organs lack Essence, referring to this. This Qi naturally rotates constantly, without human effort. Terms like Lulu, Three Carts, Yellow River, and Caoxi use such imagery, not forced by human effort. This Qi arrives at Zi hour as Yang Fire, at Wu hour as Yin Water, at Mao hour as Wood Liquid, and at You hour as Metal Essence. Mao contains Jia Wood, You contains Geng Metal. Thus, one must collect using Jia and Geng. Zi contains Wu Earth, Wu contains Ji Earth, thus operating Central Earth. Without thoroughly understanding the principles of Heaven and Earth's ascent and descent, Yin and Yang's waxing and waning, the maturity of medicinal materials, and the hidden states of Water and Fire, one cannot discuss this. Although my former master explained it in detail, later generations are confused; the more he spoke, the more they doubted. Why? Because they ultimately return to Emptiness, lacking knowledge of where to begin, causing Fetal Breathing to fail and falling into Stubborn Emptiness. Neglecting nature, indulging in delusional forcing, wastes mental energy and causes disease. "Emptiness" means it cannot be seen or heard. "Nature" means it cannot be grasped or welcomed. Current step-by-step practices of collection and fire timing are clear and precise. Observing and practicing them yields results. Before entering the room, one should understand how to set up the cauldron and collect medicine. Daily, practice sitting meditation; once settled, bone joints open, meridians connect from Bladder to夾脊 (Jiaji), moving like a wheel. Primordial One Qi naturally ascends through the Three Passes to Niwan, descends through Chonglou to Jianggong. However, its arrival and collection have specific times, requiring the auspicious moments of Jia and Geng Metal/Wood. Sit silently, without movement. Soon, heat arises in the crown, sweet dew drips from the throat. Look inward with the eyes, directing intent to send it down to Jianggong and Xuanpin, then stop. In a day, Jia corresponds to the First Quarter, Geng to the Last Quarter. From Zi to Mao is First Quarter, obtaining half a jin of Mercury; from Wu to You is Last Quarter, obtaining half a jin of Lead. Collecting half a jin each of Jia-Mercury and Geng-Lead is the natural constant. "When Lead appears and Gui is born, collect quickly" refers to collecting Wood-Mercury and Metal-Lead during Jia and Geng hours. This method of collection. Initially, time and months do not matter; accumulating over time forms the Cauldron and Furnace. The whole body is the Furnace; Jianggong is the Cauldron. Today, people mistakenly consider Huangting in the Spleen or Niwan at the crown as the Cauldron, which is incorrect. After many years, the Furnace and Cauldron are formed. Then plant the medicine; once generated, collect and refine. Accumulated collection becomes medicine, refined heat becomes Fire. Collection yields a daily measure of Jin, refinement yields Zhu. During collection, gather the vigorous Qi of Jia and Geng. In applying Fire, avoid Jia and Geng Bathing periods, noting this difference. The method of collection is like the Cauldron, relying on the eyes; welcoming with intent, sending with sight. Hence, alchemical texts mention Huangpo (Yellow Matron) and Qingnü (Blue Maiden). Huangpo is Intent; Qingnü is Eye. Welcoming with intent is Huangpo matchmaking; sending inward with sight is Qingnü conveying messages. Body Qi moves with intent. Where intent goes, Qi goes; where intent stops, Qi stops. Thus, sent into the Cauldron, it stops according to intent, no longer flowing downward. This is called planting medicine. Once medicine enters the Cauldron, Fire Timing applies. Sages transmit Medicine but not Fire, because Fire and Medicine share the same origin but different paths, similar feelings but different functions. Zi is one Yang, reaching Si is six Yangs. From Zi to Si, Fire gains six numbers, forming the Qian trigram of six Yangs. During Zi to Si, welcome with intent, called Advancing Fire, or Adding. Wu is one Yin, reaching Hai is six Yins. From Wu to Hai, Water gains six numbers, forming the Kun trigram of six Yins. During Wu to Hai, send with intent, called Retreating Fire, or Drawing. Thus, Zi-Si is Fire, Wu-Hai is Water. Speaking of Fire but not Water implies Adding is Fire, Drawing is Water. All natural, not artificial. Alchemical texts mentioning numbers in Hetu and Luoshu refer to natural Fire Timing matching generative numbers, not forcing alignment. Mentioning Morning Tun and Evening Meng, Day Ye Fu, implies silent harmony with hexagrams, not forcing alignment with lines. Regarding circulation, this Qi nourishes the Five Zang and Hundred Vessels. Hai-Zi strengthens Kidneys, Yin-Mao strengthens Liver, Si-Wu strengthens Heart, Shen-You strengthens Lungs, Chen-Xu-Chou-Wei strengthen Spleen. Naturally, this Qi circulates from the prosperous palace. No need to delusionally imagine Qi entering/leaving specific organs at specific times. However, initially establishing the Cauldron has no taboos. Act when the time comes, finish when done. For taking medicine and applying fire, choose an auspicious day to enter the room. Avoid mundane matters. Forget the four senses (eyes, ears, nose, mouth), keep the chest calm, let the empty room generate white light. Any attachment leads to loose sealing, medicine leakage, and deviation from the Dao. Inside the room, eat half-hungry, half-full, do not seek sleep. Keep the mind alert and awake. See medicine, collect it; encounter fire, apply it. Within a year, except for Mao and You months, do not apply Water and Fire. Because Mao is Wood prosperous, You is Metal prosperous; Wood prosperity leads to Fire prosperity, Metal prosperity leads to Water prosperity. Not applying Water/Fire in these two months prevents excess injury. Of twelve months, excluding Mao and You, ten remain. Thus, after ten months, the Fetus is formed. Beyond ten months, stopping Fire is called injuring the Elixir; this is Fire Timing. Ten-month Fetus formation, moved to Niwan, is called Changing Cauldrons. With sufficient fetal Qi, like a born child, nursing is needed. Thus, changing to Niwan is nursing. At this stage, no work or Fire Timing is needed, no bathing, only constant warming and nurturing. After three years and nine cycles, the Heavenly Gate opens naturally, the Infant emerges freely, ascending to Immortal status. This entire process of effort is natural, not forced, simply welcoming with intent at the right time. This is accumulating days and months to build the Cauldron and Furnace. Ten months of year, forming fetus and applying fire; my former master said the Golden Elixir shines red in one day. Others say it can be accomplished in an instant. Why? Because half a day's effort can seize one and a half years of creation. When medicine arises, welcoming in an instant is called Instant Golden Elixir, not laboring day and night. Terms like Medicine, Furnace/Cauldron, Fire Timing, Bathing, Fetal Breathing, Infant, Circulation, Adding/Drawing, Host/Guest, Floating/Sinking, Ascending/Descending, Lead/Mercury, Water/Fire, True Earth, Metal Essence, Wood Liquid—all are pseudonyms for one thing. Linked like hooks, one can discuss the meaning thoroughly. The theory of beginning in Emptiness and Nature is fully covered in my former master's alchemical verses. Consistent with *Cantong Qi*, unified in principle. Speaking is not hard, doing is hard; doing is not hard, guarding is hard. Why is guarding hard? Heterodox methods have no karmic retribution. Only the Golden Elixir has retribution. Young practitioners today require half a year of fasting, bathing, abstaining from desire, forgetting thoughts, and silent sitting to collect. When the time comes, senses and limbs become light, hundred diseases vanish. Naturally, Fire rises in kidneys, spine feels like a wheel, Niwan feels like hot water, sweet dew drips in mouth. If staying awake and preserving spirit continuously, within two months, divine light appears in eyes, mind becomes clear; if possessing wisdom, this is verification. Those who achieve this must not think it is the Ultimate Dao, otherwise madness may arise, leading to insanity. By three months, beyond applying fire, if every moment's effort is accurate, nine orifices shine, golden halo on head, seeing inside and out, connecting with spirits. At this time, the Infant has form. Do not let it move freely; guard entry and exit strictly, otherwise Fire leaks and Elixir scatters. After ten months, Infant is fully formed, naturally dropping off like ripe fruit. Entry and exit allow body movement by inches. Do not go far; if leaving, must return immediately, otherwise Spirit is stolen, path lost, reincarnation occurs, abandoning the body. Only after three years and nine cycles, bones mature, like a person knowing life's depths, can one allow natural free movement, achieving Ascension and Transformation to True Immortal status. Yet there are demonic obstacles. During deep meditation, intelligence doubles, miracles emerge. Strange events, pre/post-death immortals, ghosts and fears gather before you, seeming like clairvoyance or possession. These demonic obstacles must not be taken as Dao; firm resolve is needed. Concentrate one thought firmly, guarding true form as in *Tai Xuan*. Do not mistake illusion for truth, follow emotion as nature. Only guarding One achieves Dao. Many lack stability and insight, possessed by external evils. Not failing in study, but falling, doubting immortals' existence. Regrettable! I studied, made friends, sought masters, practiced personally, witnessing such results, telling future scholars. Aspirants who read and seek meaning, referencing former masters' works and Daoist Canon secrets, will find consistency. Practicing this, Fetus forms in ten months. After moving Cauldron and nurturing, consult higher steps, then read Zhang Wuzhen's lower volume for advancement. Rare encounters and wordless transmission will occur naturally. Without this sequence, the body lacks a master, Infant is not nurtured, Zen study is futile like water without source, wood without root, becoming Stubborn Emptiness. Below Stubborn Emptiness, no effort is made. Dantian unity is the principle of connection; any leakage leads to failure in old age, returning to evil realms of Samsara, regretting wasted effort. Refining into Elixir, uniting to become True, is connection and honesty. Further refining Dantian into Treasure is liberation and transformation, truly precious. Having real treasure, after Elixir completion, depth of cultivation and control determine retribution, which lies in effort. Never slack, never indulge. Ascension is best, Corpse Liberation second, Possession third, Reincarnation lowest. Ascension and Longevity are one; Corpse Liberation is two. Both require perfect merit and action, benefiting heaven and humanity, to achieve this. Without merit, only extending life, not becoming Immortal. Why? Spirit gone returns not, Qi cut revives not. Upper is Possession, lower is Reincarnation, lowest is wandering soul. I pity foolish talkers; thousands speak Dao, one or two succeed. Thus recording as warning for successors. Presuming to publish lightly, completing this book. Future readers, savor and study, as if facing teacher or parent, cherish deeply, keep as lifelong treasure. Show not to unworthy, transmit not to unworthy. Violating this brings disaster to self and ancestors, sinking into无间 (Avici Hell), no end. Written on Mid-Autumn Day of Jiazi Year, Xianchun Era, at Zhuling Grotto-Heaven.
