法根据闭气，行于夜半后，生气初动时，浊气口中吐之，清气鼻中纳之，子后午前各一次。
先去一切思虑，闭目冥心，盘趺而坐，握固静思集神，然后叩齿三十六。后又两手向项
后，数九息，勿令耳闻。乃移两手心掩两耳，先以第二指压中指，弹击脑后，左右各二十四次。
摇头左右顾肩膊转，随动二十四。以舌搅口齿，并左右三十六。待津液满口，漱三十六，分
作三口，如有硬咽下 然有声。龙者液也，气者虎也，液行气自奔发。乃以鼻引清气闭之
，少顷搓手令极热，微微放气出。腰后外肾为精门，搓两手心热，背后摩肾堂三十六
毕，仍收手向前握固，闭口鼻之气，想用心火下烧丹田觉热极。俯首摆撼左肩三十六，右肩三十六
。想火自丹田透双关、入脑户，鼻引清气，闭少顷，乃放直两脚，叉手向上托
天，按顶各九次。然后放下，以两手向前攀脚心十二次。乃收足端坐，候口中津液，所云逆水
上也。如无津，照前法再漱再吞三度，所得神水分三咽，乃为九也。咽下 有声，百脉自匀畅。
摆肩并身二十四次，再转辘轳二十四次，闭气想丹田火自下而上，遍烧身体，魔消梦安，寒
暑灾病皆不能入，与乾坤合矣。
闭目冥心坐，握固静思神。叩齿三十六，两手抱昆仑。左右鸣天鼓，二十四度闻。微摆撼天
柱，赤龙搅水津。漱津三十六，神水满口匀。一口分三咽，龙行虎自奔。闭气搓手热，背摩后
精门。尽此一口气，想火烧脐轮。左右辘轳转，两脚放舒伸。叉手双虚托，低头攀足频。以候逆水
上，再漱再吞津。如此三度毕，神水九次吞。咽下 响，百脉自调匀。河车搬运讫，发火遍烧身
。邪魔不敢近，梦寐不能昏，寒暑不能入，灾病不能 。子后午前作，造化合乾坤，循环次第转，八卦是良因。
练习方法依据闭气法，在夜半之后、阳气初生之时进行。将体内的浊气从口中吐出，将清新的空气从鼻中吸入，子时过后到午时之前各练习一次。
首先排除一切思虑杂念，闭上眼睛，使心神宁静，盘腿端坐，双手握固（拇指掐住无名指根部，其余四指握住拇指），静心凝神，然后叩击牙齿三十六次。接着，将双手向后伸至颈项后方，呼吸九次，声音要轻，不要让自己听到。然后将两手心捂住双耳，先用食指压在中指上，弹击脑后，左右各二十四次。
摇头并向左右张望，转动肩膀，跟随动作共二十四次。用舌头在口腔内搅动牙齿，左右各三十六次。待口中津液充满，漱口三十六次，分作三口咽下，吞咽时要发出明显的声响。中医认为“龙”代表津液，“虎”代表元气，津液运行则元气自然奔发。接着用鼻子吸入清气并暂时闭气，片刻后搓手直到极热，然后微微放出气息。腰部后面的外肾部位是精门，用搓热的两手心在背后按摩肾脏区域三十六次，结束后仍收回手向前保持握固姿势，闭住口鼻之气，意念集中于心火向下焚烧丹田，感觉热度至极。低头并摆动左肩三十六次，右肩三十六次。想象热气从丹田透过关元穴和气海穴，进入脑户穴，用鼻子吸入清气，闭气片刻，然后伸直双脚，双手交叉向上托举天空，按压头顶各九次。
然后放下双手，用两手向前攀抓脚心十二次。接着收回双脚端正坐姿，等待口中产生津液，这被称为“逆水上升”。如果没有津液，按照前面的方法再次漱口和吞咽三次，所得的神水总共分九次咽下，这才算完成一轮。吞咽时发出声响，全身经脉自然通畅均匀。摆动肩膀并转动身体二十四次，再像辘轳一样旋转身体二十四次，闭气想象丹田之火自下而上遍烧全身，这样邪魔消除，梦境安宁，寒暑灾病都不能侵入，仿佛与天地乾坤相合了。
（诗歌部分）
闭上眼睛使心神宁静而坐，双手握固以静定精神。
叩击牙齿三十六次，双手抱住后脑（昆仑）。
左右手如鸣天鼓般弹击脑后，共二十四次听闻。
轻微摆动头部如同撼动天柱骨，赤龙（舌头）搅动生出津液。
漱口三十六次，神水（津液）满口均匀。
一口分为三次咽下，龙行（津液下行）则虎奔（元气激发）。
闭气搓热双手，背部按摩后腰精门。
尽此一口气，想象火烧灼肚脐下的丹田。
左右像辘轳一样旋转身体，双脚放松伸展。
双手交叉向上虚空托举，低头频繁攀足。
等待逆水上升的津液，再次漱口吞咽津液。
如此重复三次完毕，神水共九次吞下。
吞咽发出响声，百脉自然调匀。
河车搬运（内气运行）完成后，发动真火遍烧全身。
邪魔不敢靠近，梦寐不会昏乱，寒暑不能侵入，灾病不能伤害。
在子时后到午时前练习，顺应造化与乾坤，循环次第转换，八卦是良好的因缘。
The practice method is based on breath retention (Bi Qi). It should be performed after midnight, when the vital energy (Sheng Qi) begins to stir. Expel turbid qi (Zhuo Qi) through the mouth and inhale clear qi (Qing Qi) through the nose. Perform this once between Zi hour (11 PM - 1 AM) and Wu hour (11 AM - 1 PM).
First, dispel all thoughts and worries. Close your eyes and calm your mind (Ming Xin). Sit in a cross-legged posture (Pan Fu), hold your hands in the "firm grip" (Wo Gu) position, and concentrate your spirit (Ji Shen). Then, tap your teeth thirty-six times. Next, extend both hands behind your neck and breathe nine times, ensuring no sound is heard by your ears. Then, place the palms of your hands over your ears. Press the index finger against the middle finger and flick the back of your head, doing this twenty-four times on each side. Shake your head looking left and right, and rotate your shoulders, following the movement for twenty-four repetitions. Stir your tongue around your teeth, moving it left and right thirty-six times. When saliva fills your mouth, rinse your mouth thirty-six times, then swallow in three portions, making a distinct swallowing sound. In Traditional Chinese Medicine, "Dragon" refers to saliva/fluids, and "Tiger" refers to Qi. When fluids move, Qi naturally rushes forth. Inhale clear air through the nose and retain the breath for a moment. Rub your hands until they are extremely hot, then gently release the breath. The area behind the waist, corresponding to the external kidneys, is the gate of essence (Jing Men). Rub the back of the kidneys with your heated palms thirty-six times. Return your hands forward into the firm grip position, close your mouth and nose, and visualize heart fire (Xin Huo) burning down into the Dantian (Elixir Field) until you feel intense heat. Bow your head and sway your left shoulder thirty-six times, then your right shoulder thirty-six times. Visualize the fire penetrating from the Dantian through the Shuang Guan points (Guanyuan and Qihai) into the Naohu point at the base of the skull. Inhale clear air through the nose, retain the breath briefly, then straighten your legs. Cross your hands and push upwards towards the sky, pressing against the crown of your head nine times each.
Then lower your hands and reach forward to grasp your soles twelve times. Bring your feet back to a seated upright position. Wait for saliva to accumulate in the mouth; this is referred to as "reverse water rising." If no saliva is produced, repeat the rinsing and swallowing process three times as described before. The resulting divine fluid (Shen Shui) should be swallowed in nine portions total. Swallowing with a sound ensures that the hundred meridians (Bai Mai) become smooth and unobstructed. Sway your shoulders and body twenty-four times, then rotate your body like a winch (Lu Lu) twenty-four times. Retain your breath and visualize the fire in the Dantian burning up and spreading throughout the body. This eliminates evil influences and calms dreams, preventing cold, heat, disasters, and diseases from entering, thus harmonizing with Heaven and Earth (Qian Kun).
(Poem)
Close your eyes and calm your mind while sitting, hold the firm grip to quiet the spirit.
Tap the teeth thirty-six times, embrace the Kunlun (back of the head) with both hands.
Ring the heavenly drum on both sides, hearing it twenty-four times.
Gently sway the Tian Zhu (neck/spine), let the red dragon (tongue) stir the water (saliva).
Rinse with thirty-six swallows, letting the divine fluid fill the mouth evenly.
Swallow one mouthful in three parts; as the dragon moves, the tiger runs.
Retain breath and rub hands hot, massage the rear Jing Gate on the back.
Exhale this single breath, imagine fire burning the navel wheel (Dantian).
Rotate left and right like a winch, stretch out both legs comfortably.
Cross hands and push up into the void, bow down and climb feet frequently.
Wait for the reverse water to rise, rinse and swallow again.
Complete this three times, swallow the divine fluid nine times in total.
Swallow with a sound, and the hundred meridians will naturally balance.
After the He Che (River Cart) transport is finished, ignite the fire to burn the whole body.
Evil spirits dare not approach, dreams will not cause confusion, cold and heat cannot enter, disasters and diseases cannot harm.
Practice after Zi hour and before Wu hour, creating harmony with Heaven and Earth.
Cycle through the sequence, the Eight Trigrams (Ba Gua) are the good cause.
