《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。
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.
