〔原文〕一法∶睡卧，勿张口，久成消渴及失血色，赤松于云∶卧，闭目，不息十二通，
治饮食不消。
〔解说〕人睡卧时，不要张口，否则日久会引起消渴病及使颜面失去血色。赤松子说∶
卧，闭眼，不息十二通，可治饮食不消化。
〔原文〕二法∶解衣 （谈。安静）卧，伸腰 小腹，五息止。引肾，去消渴，利阴
阳。解衣者，使无挂碍。 卧者，无外想，使气易行。伸腰，使肾无逼蹙。 者，大努使气满，
小腹者，即摄腹牵气使五息，即为之。引肾者，引水来咽喉，润上部，去消渴枯槁病。利阴
阳者，饶气力。此中数虚要与时节而为避。初食后，大饥时，此二时不得导引，伤人亦避，恶
日时节不和时亦避。导已，先行一百二十步，多者千步，然后食之。法不使大冷大热，五味调
和。陈秽宿食，虫蝎余残，不得食。少眇着口中，数嚼少湍咽。食已，亦勿眠。此名谷，并与气
和，即真良药也。
〔解说〕赤松子，古代气功家。相传汉高祖刘邦的谋士张良，曾跟随赤松子学导引辟谷术
于天门山。赤松子吃首乌、黄精，教张良行眼观鼻，鼻对脐，双肘压期门等导引术。《云笈七

解开衣服，安静而卧，伸腰，使气沉小腹，五息止，引气入肾中，可除消渴，调和阴阳。
解衣，是使导引时气行不受阻碍。静卧，是使心中没有妄想，气容易在体内营运。伸腰，是为了使
肾脏不受压迫。 腹者，是吸气使气至丹田，令小腹胀满，此时收腹聚气，五息方止。引肾，是
引肾水到咽喉，润泽上部，以祛除消渴枯槁病。调和阴阳，可使人气力健旺。在导引中如出现虚弱
现象，就要根据时节而进行避忌。刚刚进食之后和过度的饥饿时，这两个时候，不能进行导引，因其
会损伤人体。还应避开不好的日子及时辰节令不和的时候。导引完毕，要先步行一百二十步，多者
可行一千步，然后进食。进食不要太冷太热，要五味调和。陈腐的隔夜食物，虫蝎吃过的剩余食物，
都不能吃。进食时，要小口细嚼慢咽。食后，不要立即睡觉。这就叫谷药，再加上气和，可谓真正的良
药了。

本节重点讨论练功时姿式和意义，以及注意事项与饮食禁忌。所述甚详，不另再议。
一法：睡觉时，不要张开嘴巴，时间久了会形成消渴病并导致面色失去血色。赤松子说：躺着，闭上眼睛，停止呼吸十二次，可以治疗饮食不消化。
二法：解开衣服（安静地）躺下，伸展腰部至小腹，保持五息的时间后停止。引导肾气，去除消渴病，调和阴阳。解开衣服，是为了使身体没有挂碍。躺下，是为了心中没有外念，使气容易运行。伸展腰部，是为了使肾脏不受挤压。努气，是用力使气充满，小腹，就是收缩腹部牵引气使其持续五息，就这样做。引导肾气，是引水液到达咽喉，滋润上部，去除消渴枯槁病。调和阴阳，是增加气力。这里的禁忌要根据时节来避免。刚吃完饭和极度饥饿的时候，这两个时候不得进行导引，否则会伤人。也要避开恶劣的日子、时节不和的时候。导引结束后，先走一百二十步，多者一千步，然后再进食。食物不要过冷过热，五味要调和。陈腐的隔夜食物，虫蝎吃过的残余食物，不得食用。少量放入口中，多次咀嚼慢慢咽下。吃完饭后，也不要睡觉。这叫做“谷药”，再加上气和，就是真正的良药了。

Method One: When sleeping, do not open your mouth; doing so for a long time may lead to Xiao Ke disease (Wasting and Thirsting Syndrome) and cause the complexion to lose its luster. Chisongzi said: "Lie down, close your eyes, and practice breath retention twelve times; this can treat indigestion."
Method Two: Loosen your clothes and lie down quietly; extend your waist towards the lower abdomen, hold for five breaths, then stop. Guide the Qi of the Kidney to eliminate Xiao Ke disease and harmonize Yin and Yang. Loosening clothes removes physical obstructions. Lying down eliminates external thoughts, allowing Qi to flow easily. Extending the waist prevents compression of the Kidneys. "Nuding" (straining/forcing Qi) fills the body with Qi. "Lower Abdomen" refers to contracting the abdomen to draw Qi in for five breaths. Guiding the Kidney Qi draws fluid up to the throat to moisten the upper body, eliminating the dryness of Xiao Ke disease. Harmonizing Yin and Yang increases vitality. Avoid these practices when feeling weak, adjusting according to the seasons. Do not practice Daoyin (guiding and pulling exercises) immediately after eating or when extremely hungry, as it harms the body. Also avoid inauspicious days or times of seasonal disharmony. After Daoyin, walk 120 steps, or up to 1,000 steps, before eating. Food should not be too hot or cold; the Five Flavors should be balanced. Do not eat stale leftovers or food contaminated by insects. Chew food thoroughly and swallow slowly. Do not sleep immediately after eating. This is called "Grain Medicine"; combined with harmonious Qi, it is true good medicine.
Commentary: When sleeping, do not open your mouth; otherwise, over time it will cause Xiao Ke disease and make the face lose its color. Chisongzi said: "Lie down, close your eyes, and practice breath retention twelve times; this can treat indigestion."
Chisongzi was an ancient Qigong master. Legend has it that Zhang Liang, a strategist for Emperor Gaozu of Han, learned Daoyin and Bigu (grain avoidance) techniques from Chisongzi at Tianshan Mountain. Chisongzi consumed Polygonum multiflorum (He Shou Wu) and Polygonatum sibiricum (Huang Jing), and taught Zhang Liang Daoyin techniques such as gazing at the nose, aligning the nose with the navel, and pressing the Qimen acupoint with both elbows. Volume 59 of *Yunji Qiqian* contains a preface to Chisongzi's Breath-Swallowing Sutra, which states: "The Heavenly Way is long, and all things are unequal; human life is precious, sharing the same grade as Yin and Yang. The Heavenly Way is straightforward; practicing it without confusion... Therefore it is said: Ceasing grain and avoiding food is the path to life; returning essence through Yin and Yang is a great treasure. Practicing this constantly ensures longevity; why indulge desires to age oneself? Billions spend fortunes on funerals, weeping and regretting. Is it not better to practice non-action and swallow Qi, cultivating diligently to ascend to heaven?" *Biographies of Divine Immortals* states: "Chisongzi was the Rain Master during the time of Shennong; he took Jade Water to teach Shennong and could enter fire and burn himself..." This completely deifies him into a god-immortal. Historical records indicate Chisongzi was a Han Dynasty Qigong master, and his role as Zhang Liang's teacher is indeed factual.
Loosen clothes, lie down quietly, extend the waist, sink Qi into the lower abdomen, hold for five breaths, guide Qi into the Kidneys to eliminate Xiao Ke disease and harmonize Yin and Yang. Loosening clothes allows Qi to flow unimpeded during Daoyin. Quiet lying eliminates delusions, making Qi circulation easier. Extending the waist prevents kidney compression. Contracting the abdomen draws Qi to the Dantian, filling the lower abdomen; gather Qi here for five breaths. Guiding the Kidney brings Kidney water to the throat to moisten the upper part, removing the withering of Xiao Ke disease. Harmonizing Yin and Yang strengthens vitality. If weakness occurs during Daoyin, observe taboos according to the season. Do not practice Daoyin right after eating or when excessively hungry, as it damages the body. Avoid bad days and times of seasonal disharmony. After Daoyin, walk 120 steps, or up to 1,000 steps, then eat. Food should not be too hot or cold; the Five Flavors must be balanced. Stale overnight food and remnants eaten by insects must not be consumed. Eat in small bites, chew thoroughly, and swallow slowly. Do not sleep immediately after eating. This is called Grain Medicine; combined with harmonious Qi, it is truly good medicine.
Summary: This section focuses on postures and their significance during practice, as well as precautions and dietary taboos. The description is detailed, so no further discussion is needed.
