服气法，凡欲服气，即正脚卧，先叩齿三十六下，吐去浊恶气，即上下卷肚七下，左右
亦如之，各七度，此名炼气，除万病，即闭气令内不出外不入，鼓腹令气满，及微闭三五咽
以下为一歇，咽多为佳，每咽皆以意送至下丹田，脐下三寸是，亦名气海，至十歇以上，气
渐通，二十歇即腹中大转，如减食大妙，从子至巳，六时为阳气，生气在外，从午至亥，六
时为阴气，生气在内，凡吐去浊气，若阳时鼻微微引外气长取之，行下丹田饱闭之令极，口
中微微吐之，任根据常息，若阴时，但闭口内咽之以饱，任根据常息，如有他疾，即根据六气调适
之，若遇恶阴重雾雷电，只得内咽，不得取外气。
凡服气，先导引为佳，每日能咽得三五十咽津液，胜服诸药，凡运气如屋漏注连相续，
送至病处，若患时疾瘴气，但能引外气呵去之，立效。
凡服气，饮一两合暖水，水是气母，又每食前，饮少暖水，久久耐寒暑，饮多不妨。
凡为道者，当净盥漱，勿任情性，节减滋味，不欲劳形疲体，高声叫呼，嗔怒喜乐忧悲
，触冒寒暑，乃可返老还童。
凡初服气，必须心意坦然，勿疑勿畏，若有畏惧，气即难行，若四体调和，意自欣乐，
不羡一切事，即日胜一日，快乐无极，不得思食，若忽思食，必须抑捺，如不在意抑捺，即
邪干矣，可用薜荔煮汤，入生姜少许，更煮一两沸服，其饥渴即姜蜜汤亦得，若能自抑捺，
终日对嘉馔，亦无所苦。
凡服气，但不失时节，丹田当满，纵出人事，亦不可废，行之日久，虽失一时，亦无所
觉，若服气成者，终日不服气，气亦自足，至妙不可穷尽，服气得脐下丹田常满，虽叫呼读
诵，终日语言，其气力不少衰，但可行步出入少时，令气下大妙，凡服气成欲食，食亦不妨，
亦不障气，气还作声，直至脐下，一成以后，兼食行气，皆无窒碍。
凡服气，欲得身中百物不食，肠中滓秽既尽，气即易行，能忍心久作，自觉精神有异，
四体日胜，肠中既净，即闭目内视，五脏历历分明，知其处所，然后五脏可安，神常自卫，
久可别人善恶，视表如里，亦能驱使五脏之神，以治人病，其内息法，用气日久，即得多时，
若兼食饮酒浆等，即内息不成，其有宿患，但用意并气注之患处，不过三五日必愈，若四肢
有患，亦可想气以攻之，即其病随散，然初攻病时，当利五色脓，亦无足怪也。
凡服气面肿者，为饮淡水上冲，气壅不行，所以如此，食中尤忌胡荽芸台邪蒿韭薤菠
葱蒜，此物皆木之精，能损脾乱气，大不可食，夫恚怒伤魂，猝哀惊魄，哭泣之事，至人不
为，必不得已而为之，可登时于一净处，晏坐安心，用气排恶气尽出，然后根据法服元气使足
，又服丹田中气使足。
凡肠长者气易固，肠短者难固，如肠中搅转作声，即须右胁着床，以右手枝头，以左手
牵脚令屈，直身及直右脚，咽气令人右脚中，出肠中即可，久行气，每下作声，声绕盘屈于
肠屈处，作声皆自记得屈处，其声流转，呦呦然小声，即是流通肠中四缘，又有节坎，有二
十四坎，久行每气下，即觉在节坎，坎数亦自记得，元气与外气不相杂，若咽生风，须叟即
从下泄出，不得停肠中。
服气法，凡是想要练习服气，就端正双脚躺下，先叩击牙齿三十六次，呼出体内浑浊恶浊之气，接着上下卷动腹部七次，左右侧身也这样做，各做七遍，这叫做炼气，可以消除各种疾病。然后闭住气息，使其内部不排出、外部不进入，鼓胀腹部使气充满，等到微微闭上口鼻，每吞咽三五次作为一次休息，吞咽次数多更好，每次吞咽都要用意念将气送至下丹田，即脐下三寸处，这里也叫气海，做到十次以上休息，气逐渐通畅，二十次休息时腹部会有大的转动，如果能减少饮食则更加美妙。从子时到巳时，这六个时辰属于阳气，生气在体外；从午时到亥时，这六个时辰属于阴气，生气在体内。凡是呼出浊气时，如果在阳时，鼻子微微吸入外气并长取之，行气至下丹田饱满后闭气至极，口中微微吐出，任凭按照常规呼吸；如果在阴时，只需闭口内咽直到饱足，任凭按照常规呼吸。如果有其他疾病，就根据六气进行调适。如果遇到恶劣的阴气、浓雾、雷电天气，只能内咽，不得吸入外气。
凡是练习服气，先进行导引运动为佳，每天如果能吞咽三五十次津液，胜过服用各种药物。凡是运气如同屋漏滴水连续不断，送至病患之处。如果患有时行疫病或瘴气，只要能引入外气呵斥出去，立刻见效。
凡是练习服气，饮用一两合温水，水是气的根本，又在每顿饭前，喝少量温水，久而久之能耐寒暑，多喝也无妨。
凡是修道之人，应当洁净盥洗漱口，不要放纵性情，节制减少滋味，不要劳累形体疲乏身体，高声叫喊呼号，嗔怒喜乐忧悲，触犯冒犯寒暑，才可以返老还童。
凡是初次练习服气，必须心意坦然，不要怀疑不要畏惧，如果有畏惧心理，气就难以运行，如果四肢调和，心意自然欣喜快乐，不羡慕一切事物，一天比一天好，快乐无穷无尽，不需要思考食物，如果忽然想吃东西，必须抑制忍耐，如果不注意去抑制忍耐，邪气就会干扰，可以用薜荔煮汤，加入少许生姜，再煮一两沸后服用，其饥渴感即可缓解，姜蜜汤也可以。如果能自我抑制忍耐，整天面对美味佳肴，也没有痛苦。
凡是练习服气，只要不失时节，丹田应当饱满，纵然处理人事，也不可废弃。行之日久，即使失去一时，也不会有什么感觉。如果服气有成的人，整天不服气，气也自然充足，到了妙处不可穷尽。服气得法使得脐下丹田常满，即使叫呼喊号诵读，整天说话，其气力也不会丝毫衰减，只要可行走出入稍作活动，让气下沉则非常美妙。凡是服气有成想要进食，进食也无妨碍，也不阻碍气，气还能发出声音，直至脐下，一旦形成之后，兼食行气，都没有阻碍。
凡是练习服气，想要得到身体中百物不食，肠中渣滓污秽既然排尽，气就容易运行，能忍心长久坚持，自觉精神有异样，四肢日益强健，肠中既然干净，就闭目内视，五脏历历分明，知道它们的位置，然后五脏可以安宁，神经常自保卫，久了可以辨别别人善恶，看外表如同看内部，也能驱使五脏之神，来治疗人的疾病。其内息之法，用气日久，就能维持很长时间，如果兼吃饮酒浆等，内息就不能成功。那些有旧疾的人，只需用意并将气注于患处，不过三五天必定痊愈。如果四肢有病患，也可以想气去攻击它，病随即消散。然而初攻病时，应当利出五色脓，也不必奇怪。
凡是服气导致面部肿胀的，是因为饮用淡水上冲，气壅滞不行，所以如此。食物中尤其忌讳胡荽（香菜）、芸台（油菜）、邪蒿、韭菜、薤（小根蒜）、菠菜、葱、蒜，这些物品都是木之精气，能损伤脾胃扰乱气机，绝对不可食用。发怒伤魂，突然悲哀惊魄，哭泣的事情，得道的人不做，如果不得已而为之，可以立即在一个干净的地方，安坐安心，用气排出恶气尽出，然后根据方法服元气使其充足，又服丹田中的气使其充足。
凡是肠道长的气容易固守，肠道短的气难固守。如果肠中搅转作响，就必须右侧卧着床，用右手手指头，用左手牵拉脚使其弯曲，伸直身体及伸直右脚，咽气使人右脚中，出肠中即可。久行气，每次下行作响，声音环绕盘屈在肠子的弯曲处，发声都自己记得弯曲处，声音流转，呦呦然小声，这就是流通肠中四缘，又有节坎，有二十四坎，久行每次气下，就觉得在节坎，坎数也自己记得。元气与外气不相混杂，如果咽生风，须臾就从下面泄出，不得停留在肠中。
Qigong (Breath Regulation) Method: To practice Qigong, lie flat with feet straight. First, tap the teeth thirty-six times to expel turbid and foul qi (vital energy). Then, roll the abdomen up and down seven times, and do the same on the left and right sides, each for seven repetitions. This is called "Refining Qi" (Lianqi), which eliminates myriad diseases. Next, hold the breath so it neither exits internally nor enters externally, distend the abdomen until full of qi. Swallow three to five times as one rest period; swallowing more is better. With each swallow, use intention to guide the qi to the Lower Dantian (Lower Elixir Field), located three cun below the navel, also known as the Sea of Qi (Qihai). After ten rest periods, the qi gradually becomes unobstructed; after twenty rest periods, there will be significant movement in the abdomen. Reducing food intake is highly beneficial. From Zi hour to Si hour (midnight to 11 a.m.), these six hours belong to Yang Qi, where generating qi is external; from Wu hour to Hai hour (noon to 9 p.m.), these six hours belong to Yin Qi, where generating qi is internal. When expelling turbid qi during Yang hours, gently inhale external air through the nose, extend it deeply, fill the Lower Dantian, hold the breath to the limit, and gently exhale through the mouth, then resume normal breathing. During Yin hours, simply close the mouth and swallow internally until full, then resume normal breathing. If suffering from other ailments, adjust according to the Six Qi (Six Climatic Factors). In cases of severe Yin conditions, heavy fog, or thunderstorms, only swallow internally and do not inhale external air.
For Qigong practice, leading with Daoyin (Guiding and Pulling exercises) is best. Swallowing thirty to fifty portions of saliva daily is superior to taking various medicines. When circulating qi, imagine it flowing continuously like water dripping from a leaking roof, directed to the diseased area. For epidemic fevers or miasma, introducing external air and exhaling forcefully can produce immediate effects.
When practicing Qigong, drink one or two he of warm water, as water is the mother of qi. Drinking a small amount of warm water before each meal helps build resistance to cold and heat over time; drinking more is harmless.
Practitioners must cleanse their mouths and hands, avoid indulging in emotions, reduce rich flavors, prevent physical exhaustion, avoid shouting, extreme anger, joy, sorrow, or exposure to cold and heat, in order to reverse aging and regain youth.
Initially, maintain a calm mind without doubt or fear; fear hinders qi flow. If the four limbs are harmonious, the mind naturally rejoices, free from worldly desires, improving day by day with boundless joy. Suppress thoughts of food; if cravings arise, restrain them. Failure to restrain may allow pathogenic factors to interfere. In such cases, boil Ficus pumila (Bili) soup with ginger and consume it; honey-ginger tea is also effective. Self-restraint allows one to face delicacies without distress.
Maintain proper timing and keep the Dantian full; do not neglect practice despite daily affairs. With long-term practice, temporary lapses go unnoticed. Once proficient, one feels energetic even without active practice. The Lower Dantian remains full; speaking or chanting does not deplete strength. Walking briefly helps sink the qi. Eating does not obstruct qi once proficiency is achieved; qi circulates freely to the Dantian.
With prolonged practice, intestinal waste clears, facilitating qi movement. Mental endurance leads to spiritual changes and stronger limbs. Closing eyes and visualizing internally reveals the five Zang organs clearly, allowing them to settle and protecting the Shen (Spirit). One may discern good and evil, see inside as outside, and direct the spirits of the five Zang organs to treat diseases. Internal breathing requires sustained practice; alcohol and rich foods hinder success. For chronic illnesses, focus intention and qi on the affected area; recovery occurs within three to five days. For limb ailments, visualize qi attacking the disease, causing it to dissipate. Initial treatment may expel pus of five colors, which is normal.
Facial swelling during Qigong results from drinking light water rising upward, causing qi stagnation. Avoid coriander, rapeseed, wormwood, garlic chives, wild leeks, spinach, onions, and garlic, as they damage the Spleen and disrupt qi. Anger harms the Hun (Ethereal Soul); sudden grief startles the Po (Corporeal Soul). Sages avoid crying; if unavoidable, sit calmly in a clean place, expel bad qi with breath, then replenish Yuan Qi (Original Qi) and Dantian qi.
Long intestines retain qi easily; short ones do not. If intestines rumble, lie on the right side, bend the left leg with the left hand, straighten the body and right leg, and swallow qi into the right foot to clear the intestines. Long-term practice produces sounds circling intestinal bends. One remembers the bends and the sound's flow. There are twenty-four "nodes" (Kan) in the intestines. Original Qi and external Qi must not mix; swallowed wind must exit quickly.
