〔解说〕入水法，练功时需举两手臂，不息行气，此即所谓不伤水的功法，“不没法”
参照入火法，按“不伤法”解释。
1、面向北方，箕踞而坐，用两手拉两脚的五趾，可治疗大腿痿软，腰 部筋脉拘急。
2、采用屈膝张脚踞坐势，用两手从腿弯处伸入按地，把脚放在手上，抬起臀部。还可以同
时配合行气。能治愈小便淋漓，乳痛。
举脚交叉向项后，用两手按地，举臀使臀高抬起，达到
最大限度，交两脚于项上。能治疗腹中胀满不适，除三虫，疏通五内，畅快神气。
4、采用下蹲势，下蹲时使两脚尽量近似成为一条直线，即所谓的尽力横蹲；并用两手握
住两脚趾，尽力向上提，使脚趾离地。这种功法能治疗气冲腹肿痛，寒疝上下出入，使肾
气通畅。
5、采用屈膝如坐的蹲踞势，用两手搬起两脚的五趾，尽力低头，使五脏之气都达到头上。可
治疗耳听不聪，目昏视物不明。长施这种功法，可使白发重新变黑。
6、正仰卧，两手卷成握式，闭气不息，行气沿腿至脚跟止，两腿足根据在床上。可治阴结
，筋脉麻木，痿软、或拘挛。将两手松开，按在腋下，治胸中胀满，头眩，手枯萎不用。
7、反翻两手按在膝上，仰头仿鳖仰天引颈吸气那样吸气，引气到中丹田，使中丹田元气到下
丹田，可使腰脊疼痛消失。大黄元气即中丹田元气。
8、用手大拇指很快地捻鼻孔，闭气不息，引气上行达泥丸脑中，可使阴阳顺从其数，收到
强壮健身令人不易疲倦的效果。
9、用左手很快地握住头发，右手环绕从后项出，这就是所谓的血、脉、气各流其根，闭藏太阳
经脉之气，使阴气不外流。此功法的确是通调阴阳的有效方法。
10、正坐位，用两手交叉在背后，名为带缚。能治疗大便困难，通利腹部，并可治疗虚劳羸瘕。
11、坐在地上，用手交叉放在脐下，能治疗会阴胀满不适。
12、用两手抓住绳子，倒悬在辘轳上。辘轳是汲取井水的起重置备。本功法可利用此设备，使
脚在上，头在下，令身离
地，用以治疗头晕风癫病。用两手反牵绳于背上，拉绳自悬于空中。可治愈中焦脾气
不能健运，食欲不佳的病症。用一只手在上面牵拉绳，另一只手在下面拉住脚，可治
愈久痔及尾 部肿痛。
13、坐在地上，伸直两脚，用两只手交叉挽拉两脚，尽量用力，能治疗肠胃不能受

小结∶
1、入水法探讨
《云笈七签》∶“ 月精法∶ 月精，凡月初时、月中时、月入时，向月正立，
不息八通，仰头 月精，八咽之，令阴气长。妇人 之，阴精益盛，子道通。凡入水，
举两手臂不息，没。”《悟真篇注疏》曰∶“息火谓之沐浴”，沐浴就是入水洁身。
这里“凡入水”可以理解为∶吸月精太过，致使阴气偏胜，人身如水被浴，或似入于水
中，肢体发冷。此时当举两手臂不息，以引火升阳，消散阴气，不使阴气淹没阳气，使火
灭息。王冰说∶“益火之源，以消阴翳”，即是此意。本篇“入水法∶入水，举两手臂
不息，不没法”，就是说练功补阴如入水沐浴后，当举两手臂不息以引阳升火，使水不要
淹没火。入水和入火都是练功中的两大注意事项和原则，故本书独立设题以引人注意。
2、鳖取气法
其功法见“龟行气法”。本段强调此功也可用“反两手据膝，仰头像鳖取气，致大黄
元气至丹田”，而前法主张衣被盖口鼻，各有所仿效之处。土位中央，其色正黄，色黄而体
大，故名大黄。此处的大黄即中丹田，鳖息深长细匀，仿效纳之，则应力求深长，使气由
中丹田直至下丹田。
Water Immersion Method: When practicing, raise both arms and hold the breath; this is the method of not sinking.
1. Face north and sit in a spread-legged posture (legs extended forward and apart, buttocks on the ground). Use both hands to grasp or pull the five toes of the feet. This can treat flaccidity of the muscles on the anterior thigh and stiffness of the tendons in the buttocks.
2. Sit in a spread-legged posture. Insert both hands from the bent calves to press against the ground, place the feet on the hands, and lift the buttocks. This movement can be used for circulating Qi. It can treat dribbling urination and breast pain.
3. Cross the feet behind the neck, press the hands against the ground, and lift the buttocks, holding the position until the breath reaches its limit, then cross the feet above the neck. This can treat abdominal distension and discomfort, eliminate internal parasites, benefit the five Zang organs, and refresh the Shen (Spirit).
4. Adopt a squatting posture. Use both hands to lift the feet, squatting to the limit with legs spread horizontally as much as possible. This treats swelling and pain in the abdomen caused by rushing Qi, cold hernia moving up and down, and helps to consolidate Kidney Qi.
5. Adopt a squatting posture. Use both hands to lift the five toes of the feet and bow the head as low as possible. This causes the Qi of the five Zang organs to gather in the head, treating deafness and blurred vision. Long-term practice can turn white hair black again.
6. Lie supine. Curl both hands into fists, hold the breath, and let the Qi flow along the legs to the heels, with the heels supporting on the bed. This treats Yin binding syndrome, numbness and flaccidity of the tendons and vessels, or spasms.
7. Withdraw both hands and press them against the armpits. This treats chest fullness, dizziness, and withered/weak hands.
8. Place the backs of the hands on the upper knees, look upward, and inhale like a turtle to draw in Qi. Guide the "Da Huang Yuan Qi" (Yuan Qi of the Middle Dantian) to the Dantian, eliminating pain in the waist and spine.
9. Quickly twist the nostrils with the thumbs, hold the breath, and guide the Qi upward to the Niwan Palace (brain). This aligns Yin and Yang with natural laws, resulting in resistance to fatigue.
10. Grasp the hair quickly with the left hand, and loop the right hand around the back of the neck to extend outwards. This is referred to as blood, vessels, and Qi returning to their roots. It closes the Qi of the Taiyang meridian, preventing Yin Qi from leaking outward. This is indeed an effective method for regulating Yin and Yang.
11. Sit upright with both hands crossed behind the back, named "Dai Fu" (Belt Binding). This treats constipation, promotes bowel movement, and cures emaciation due to deficiency. Sitting on the ground with hands crossed below, it treats fullness in the perineum.
12. Grasp the rope on the windlass with both hands and hang upside down, so that the feet are above the head. This treats dizziness and wind-epilepsy. Pull the rope backwards onto the back and suspend oneself. This treats dysfunction of the Spleen in the Middle Jiao and difficulty swallowing food. Hold the rope with one hand above and grasp the foot with the other hand below; this treats chronic hemorrhoids and swelling/pain in the coccyx area.
13. Sit on the ground, straighten both legs, and use both hands to cross-pull the feet, exerting maximum effort. This treats gastrointestinal inability to receive food and vomiting with rebellious Qi.
