《道藏》有《玉轴经》，言五脏六腑之气，因五味熏灼不和，六欲七情积久生疾，内
伤脏腑，外攻九窍，以至百骸受病，轻则痼癖，甚则盲废，又重则丧凶。故太上悯之，以六字气
诀治五脏六腑之病。其法以呼而自泻出脏腑之毒瓦斯，以吸而自探天地之清气。当日小验，旬
日大验，年后万病不生，延年益算。卫生之宝，非人勿传。呼有六，曰∶呵、呼、 、嘘、
嘻、吹也。吸则一而已，呼有六者，以呵字治心气，以呼字治脾气，以 字治肺气，以嘘字治
肝气，以嘻字治胆气，以吹字治肾气。此六字气诀分主五脏六腑也。凡天地之气自子至巳
为六阳时，自午至亥为六阴时。如阳时则对东方，勿尽闭窗户，然忌风入，乃解带正坐，叩齿
三十六以定神，先搅口中浊津漱炼二三百下，候口中成清水，即低头向左而咽之，以意送下。
候拍拍至腹间，即低头开口先念呵字，以吐心中毒瓦斯，念时耳不得闻呵字声，闻即气粗及损心
气也。念毕仰头闭口，以鼻徐徐吸天地之清气，以补心气。吸时耳亦不得闻吸声，闻即气贫，
亦损心气也。但呵时令短，吸时令长，即吐少纳多也。吸讫，即又低头念呵字，耳复不得闻呵
字声，呵讫，又仰头以鼻徐徐吸清气以补心，亦不可闻吸声。如此吸者六次，即心之毒瓦斯渐
散，又以天地之清气补之，心之元气亦渐复。夫再又根据此式念呼字，耳亦不闻呼声，又吸以
补脾，耳亦不可闻吸声。如此者六，所以散脾毒而补脾元也。次又念 字以泻肺毒，以吸而补
肺元，亦须六次。次念嘘字以泻肝毒，以吸而补肝元。嘻以泻胆毒，吸以补胆元。吹以泻肾
毒，吸以补肾元。如此并各六次，是谓小周。小周者六六三十六也。三十六而六气遍，脏腑之
毒瓦斯渐消，病根渐除，胆气渐完矣。以看是何脏腑受病，如眼病，即又念嘻嘘二字各十八遍，
仍每次以吸补之，总之为三十六讫，是为中周。中周者，第二次三十六通为七十二也。次又再
根据前呵、呼、 、嘘、嘻、吹六字法各为六次，并须呼以泻之，吸以补之，愈当精处，
不可怠废。此第三次三十六也，是为大周。即总之为一百单八次，是谓百八诀也。午时属阴时，
有病即对南方为之。南方属火，所以却阴毒也。然又不若子后巳前面东之为阳时也。如早起床
上面东将六字各为六次，是为小周，亦可治眼病也。凡眼中诸证惟此诀能去之，他病亦然。
神乎！神乎！此太上之慈旨也，略见《玉轴真经》，而详则得之师授也。如病重者每字作五
十次，凡三百而六脏周矣。乃漱炼咽液叩齿讫，复为之，又三百次讫，复漱炼咽液叩齿如初。
如此者三，即通为九百次，无不愈。秘之秘之，非人勿传。
《道藏》中收录有《玉轴经》，其中论述了五脏六腑之气，因五味（酸、苦、甘、辛、咸）的熏蒸灼烧而导致不和，加上长期的六欲（眼、耳、鼻、舌、身、意之欲）和七情（喜、怒、忧、思、悲、恐、惊）积聚，从而产生疾病。这些疾病内伤脏腑，外攻九窍（指眼、耳、鼻、口及前后二阴），导致全身骨骼肢体受病。轻则形成顽固的癖积，重则导致失明或残疾，更严重的则会丧命。因此，太上（道教尊称最高神祇）怜悯世人，用六字气诀来治疗五脏六腑的疾病。
其方法是：通过呼气将脏腑中的毒气排出，通过吸气吸纳天地的清气。当天就能见到小效，十天能见到大效，一年后百病不生，延年益寿。这是养生的宝物，非合适的人不要传授。
呼气有六种字，分别是：呵、呼、吹、嘘、嘻、吹。（注：原文此处“吹”字重复，且缺“呬”字，根据中医传统六字诀通常为呵、呼、呬、嘘、嘻、吹。但依据原文忠实翻译，原文列出的顺序为：呵、呼、[缺失/误写]、嘘、嘻、吹。仔细核对原文：“曰∶呵、呼、 、嘘、 嘻、吹也。” 中间有一个空格或漏字，通常第六字诀对应肺为“呬”，对应肾为“吹”。原文前文说“以吹字治肾气”，后文列举时“吹”在最后。中间那个空格处原文似有缺漏，结合后文“以 字治肺气”，该字应为“呬”。但在翻译时需忠实于提供的文本结构，若原文确实缺字，则按缺字处理或根据上下文补全逻辑。观察原文：“以呵字治心气...以 字治肺气...以吹字治肾气”。原文列举呼字时：“曰∶呵、呼、 、嘘、 嘻、吹也。” 第三个字位置为空或乱码。根据后文解释，“以 字治肺气”，故第三个字应为治肺的字，即“呬”。为了准确翻译，我将把原文中隐含的治肺之字译为“呬”或直接指出原文空缺，但考虑到任务要求不增添内容，我将保留原文的空缺感或根据标准六字诀常识推断为“呬”，鉴于“以 字治肺气”明确指出了功能，此处翻译为“呬”更符合医理逻辑，但若严格不增添，则需标注。然而，通常古籍OCR识别错误会导致漏字。此处假设第三个字为“呬”以完成六字诀的完整性，或者仅翻译可见部分。再看原文：“曰∶呵、呼、 、嘘、 嘻、吹也。” 这里有个明显的空格。后文解释：“以 字治肺气”。因此，这个空格代表“呬”。我将翻译为“呬”。）
具体对应关系为：用“呵”字调理心气，用“呼”字调理脾气，用“呬”字调理肺气，用“嘘”字调理肝气，用“嘻”字调理胆气，用“吹”字调理肾气。这六个字的气诀分别主治五脏六腑的疾病。
凡是天地之气，从子时到巳时为六个阳时，从午时到亥时为六个阴时。如果在阳时练习，应面向东方，不要完全关闭窗户，但要忌讳风邪侵入。解开衣带，端正坐姿，叩齿三十六次以安定心神，先搅动口中的津液漱口炼化二三百下，等到口中津液变成清水状，就低头向左吞咽，用意念将其送下。等到感觉津液拍打到腹部时，就低头张口先念“呵”字，以吐出心中的毒气。念的时候耳朵听不到“呵”的声音，如果听到了，说明气息粗重，会损伤心气。念完后仰头闭口，用鼻子慢慢吸入天地的清气，以补充心气。吸气时耳朵也听不到吸气的声音，如果听到了，说明气息微弱，也会损伤心气。只是“呵”的时间要短，“吸”的时间要长，这就是吐少纳多。吸气结束后，再次低头念“呵”字，耳朵依然不能听到“呵”的声音。“呵”完之后，又仰头用鼻子慢慢吸入清气以补心，同样不能听到吸气声。像这样呼吸六次，心中的毒气就会逐渐消散，并用天地的清气补充它，心的元气也就逐渐恢复。
接着再按照同样的方式念“呼”字，耳朵听不到“呼”的声音，然后吸气以补脾，耳朵也不能听到吸气声。像这样进行六次，所以能散除脾毒并补充脾元。接着念“呬”字以泻肺毒，吸气以补肺元，也必须进行六次。接着念“嘘”字以泻肝毒，吸气以补肝元。“嘻”字以泻胆毒，吸气以补胆元。“吹”字以泻肾毒，吸气以补肾元。像这样每种各进行六次，这叫作“小周”。“小周”就是六六三十六次。三十六次后，六气遍行，脏腑的毒气逐渐消除，病根逐渐除去，胆气也逐渐完备了。
如果是看哪个脏腑受了病，比如眼病，就再念“嘻”、“嘘”二字各十八遍，仍然每次都要配合吸气来补充，总共加起来是三十六遍，这叫作“中周”。“中周”就是第二次的三十六通，共计七十二次。接着再按照前面“呵、呼、呬、嘘、嘻、吹”六字的方法，每个字各做六次，都必须呼气以泻之，吸气以补之，越精细越好，不可懈怠废弃。这是第三次的三十六次，这叫作“大周”。总之是一百零八次，这叫作“百八诀”。
午时属于阴时，如果有病就面向南方练习。南方属火，所以可以驱除阴毒。但这不如子时之后、巳时之前面向东方练习那样顺应阳气。如果早晨起床后面向东，将六字各做六次，这是“小周”，也可以治疗眼病。凡是眼中的各种病症，只有这个诀法能去除，其他疾病也是如此。神奇啊！神奇啊！这是太上的慈悲旨意，大致见于《玉轴真经》，而详细的内容则是从老师那里传授得到的。如果病情严重，每个字做五十次，总共三百次，六脏就循环一周了。在漱口炼化咽液、叩齿结束后，再做一遍，又是三百次，做完后再漱口炼化咽液、叩齿如初。像这样重复三次，总共就是九百次，没有治不好的。保密啊！保密啊！非合适的人不要传授。
The *Daozang* (Taoist Canon) contains the *Yuzhou Jing* (Jade Axis Scripture), which discusses how the Qi of the Five Zang and Six Fu organs becomes disharmonious due to the薰灼 (scorching/marring) effects of the Five Flavors (sour, bitter, sweet, pungent, salty). Long-term accumulation of the Six Desires (desires of the six senses) and Seven Emotions (joy, anger, worry, thought, grief, fear, fright) generates disease. These diseases internally injure the Zang-Fu organs and externally attack the Nine Orifices (eyes, ears, nostrils, mouth, urethra, and anus), leading to illness in the entire skeletal system. Mild cases result in stubborn accumulations or masses; severe cases lead to blindness or disability; even heavier cases result in death. Therefore, Taishang (the Supreme Deity) pities sentient beings and uses the Six-Character Qi Mantra to treat diseases of the Five Zang and Six Fu organs.
The method involves exhaling to discharge toxic gases from the Zang-Fu organs and inhaling to draw in the clear Qi of Heaven and Earth. Small effects are seen within a day, major effects within ten days, and after one year, myriad diseases will not arise, extending life and increasing longevity. This is a treasure for health preservation; do not transmit it to unworthy persons.
There are six characters for exhalation: He (呵), Hu (呼), Si (呬), Xu (嘘), Xi (嘻), and Chui (吹). There is only one character for inhalation. The reason there are six exhalation characters is that "He" treats Heart Qi, "Hu" treats Spleen Qi, "Si" treats Lung Qi, "Xu" treats Liver Qi, "Xi" treats Gallbladder Qi, and "Chui" treats Kidney Qi. These six characters of the Qi Mantra respectively govern the Five Zang and Six Fu organs.
Generally, the Qi of Heaven and Earth consists of six Yang hours from Zi hour to Si hour, and six Yin hours from Wu hour to Hai hour. If practicing during Yang hours, face East. Do not close windows completely, but beware of wind entering. Loosen clothing, sit upright, click teeth thirty-six times to stabilize the mind. First, stir the turbid saliva in the mouth, rinse and refine it two or three hundred times, until it becomes clear water. Then lower the head and swallow to the left, using intention to send it down. Wait until you feel it patting against the abdomen. Then lower the head, open the mouth, and first recite "He" to expel toxic gas from the heart. While reciting, one must not hear the sound of "He" with one's own ears; if heard, the breath becomes coarse and damages Heart Qi. After reciting, raise the head, close the mouth, and slowly inhale the clear Qi of Heaven and Earth through the nose to supplement Heart Qi. While inhaling, one must not hear the sound of inhalation; if heard, the breath becomes weak and also damages Heart Qi. The duration of "He" should be short, while the duration of inhalation should be long, meaning less is expelled and more is absorbed. After inhalation, lower the head again to recite "He," ensuring the ears do not hear the sound. After "He," raise the head and slowly inhale clear Qi through the nose to supplement the Heart, again without hearing the inhalation sound. Repeat this cycle of inhalation and exhalation six times. The toxic gas of the Heart will gradually dissipate, supplemented by the clear Qi of Heaven and Earth, and the Yuan Qi of the Heart will gradually recover.
Next, follow this same pattern to recite "Hu." The ears must not hear the sound of "Hu." Inhale to supplement Spleen Qi; the ears must not hear the inhalation sound. Repeat this six times to scatter Spleen toxicity and supplement Spleen Yuan Qi. Next, recite "Si" to drain Lung toxicity and inhale to supplement Lung Yuan Qi, also repeating six times. Next, recite "Xu" to drain Liver toxicity and inhale to supplement Liver Yuan Qi. Recite "Xi" to drain Gallbladder toxicity and inhale to supplement Gallbladder Yuan Qi. Recite "Chui" to drain Kidney toxicity and inhale to supplement Kidney Yuan Qi. Each of these is performed six times. This is called the "Small Cycle" (Xiao Zhou). "Small Cycle" refers to six cycles of six, totaling thirty-six repetitions. After thirty-six repetitions, the Six Qi circulate fully, the toxic gases of the Zang-Fu organs gradually diminish, the root of the disease is gradually removed, and the Qi of the Gallbladder is gradually restored.
If observing which Zang-Fu organ is diseased, for example, eye disease, recite "Xi" and "Xu" eighteen times each, still supplementing with inhalation each time. In total, this amounts to thirty-six repetitions, which is called the "Medium Cycle" (Zhong Zhou). The "Medium Cycle" is the second set of thirty-six, totaling seventy-two repetitions. Next, repeat the previous method of "He, Hu, Si, Xu, Xi, Chui," each character performed six times. Exhale to drain and inhale to supplement. Practice with greater precision and do not neglect this. This is the third set of thirty-six, called the "Great Cycle" (Da Zhou). In total, this is one hundred and eight repetitions, known as the "Hundred-Eight Mantra" (Bai Ba Jue).
Wu hour belongs to Yin hours. If treating illness, face South. South belongs to Fire, so this can repel Yin toxicity. However, this is not as effective as facing East during the Yang hours between Zi and Si hours. If rising early and facing East, performing six repetitions of each of the six characters constitutes the "Small Cycle," which can also treat eye diseases. All various conditions of the eyes can be eliminated by this mantra alone; the same applies to other diseases. Miraculous! Miraculous! This is the compassionate decree of Taishang. It is briefly seen in the *Yuzhou Zhenjing* (True Scripture of the Jade Axis), but the detailed instructions were received from teacher transmission. If the disease is severe, perform each character fifty times, totaling three hundred repetitions, completing one cycle of the six Zang organs. After rinsing, refining, swallowing saliva, and clicking teeth, repeat the process for another three hundred repetitions. After finishing, rinse, refine, swallow saliva, and click teeth as before. Repeat this entire sequence three times, totaling nine hundred repetitions. No disease will remain unhealed. Keep it secret! Keep it secret! Do not transmit to unworthy persons.
