论曰∶用禁大例，诵禁文必不得出声，令自耳闻声，若闻之咒即禁法不得，行之无益，
慎之慎之。受禁之时，不得令人畜等一切见之，见之即不成，受法时，刀及水盆，皆不得曾
经酒肉五辛用者。
《神仙经》曰∶对治禁，万病击同类。
逢水难，土王击之；逢土难，木王击之；逢刀难，阳精击之；逢鬼精，桃汤击之；逢虎
难，五常气击之。万病击同类对治，皆持刀持桃持火持鉴持水持绳持药持符持戟持弓持箭持
驽持食持坐持粉持意持神持想持气持书持石持土持盐持幡持脂持肉持血持面持金持玉持印，
故其法皆禁击之，所须用禁之法，有请有告有祭，有害（善神即饮食祭之、住之，恶鬼即克
之、却之）有杀有畏，有爱有喜有恶有死，有走有住有灭，是故对治用时各各条例。
《仙经》曰∶用禁有六法，一牙齿禁，意存气至牙齿，二营目禁，开一目闭一目，三意
想禁，存意以去想诸疾以除，四捻目禁，谓手上有一十五日，五气道禁，谓吹呼呵嘘嘻 ，
六存神禁，存诸神在，以食醮祭之，感天灵气至，又鸣天鼓叩齿是也。
凡为人请疗疾，出门三步咒曰∶天杀黄黄，地杀正方，千鬼万神，谁复敢藏？飞步一及
，百鬼灭亡。急急如律令。
若至主人家，先当解秽，即作五龙水法，手持水碗咒曰∶东方青龙含水来，南方赤龙含
水来，西方白龙含水来，北方黑龙含水来，中央黄龙含水来。五方五龙吐水没杀邪鬼，急急
如律令讫，叩齿三百遍。
咒曰∶神水解天秽、地秽、生秽、死秽、人秽、鬼秽、身秽、病患之秽，速除去之，立
令清净，急急如律令。三嘘三叱，以刀右搅三回，以右足跟蹴地三下，含水四方喷之，及喷
病患上，尽令清洁，然后按法思神行禁。又存气至牙齿，令住闭一目，存意已去即捻目。然
后用存七星在其顶上，存青龙白虎朱雀玄武来护身，存大神在其前后五星，存之腹内，吐气
存如云，击彼处令如徐行。行步法乾坤，如此行按，即外邪不入五脏，神明自通。仍皆须审
之，万不失一。
又法∶欲向病患家，当须存想，作白虎吐火，烧病患家屋舍，皆令荡尽。又作龙舐病患
身肉令尽。还作充满悦泽，然后用气急治之。欲击物，一一皆如是。此令行禁神明万物，皆
神效验，须精审之。若唾热病，以冷气吹之二七，然后禁之。若唾冷病，以热气呵之二七，
然后禁之，三唾之后行禁，禁后三唾乃放之。
仙经曰∶受符禁同法，先当修身洁己，安魂定魄，口勿妄言，洁斋百日，可致神仙，避
逆恶气，除灭灾祥，可以长生。
论曰：使用禁咒的大致原则是，诵读禁文时绝对不能发出声音，只能让自己耳朵听到即可。如果让别人听到了咒语，那么禁法就失效了，施行起来毫无益处，务必谨慎再谨慎。在接受禁法的时候，不能让任何人或牲畜看见，一旦被人看见，禁法就不灵验了。在受法期间，所用的刀具和水盆，都不得曾经接触过酒、肉以及五辛（葱、蒜、韭、薤、兴渠）。
《神仙经》说：针对治疗禁法，万物皆以同类相克的原则进行对治。
遇到水难，用土德之气去克制它；遇到土难，用木德之气去克制它；遇到刀兵之难，用阳精之气去克制它；遇到鬼怪精魅，用桃汤去克制它；遇到老虎之难，用五常之气去克制它。对于万病采用同类相克的对治方法，无论是手持刀、桃枝、火、镜子、水、绳子、药物、符箓、戟、弓、箭、弩、食物、坐姿、粉末、意念、神灵、想象、气、书卷、石头、泥土、盐、幡旗、油脂、肉类、血液、面部表情、金属、玉石、印章等，这些方法都是通过禁咒来克制它们。所需使用的禁法，包括有请告、有祭祀、有害恶（善神则通过饮食祭祀来留住它，恶鬼则通过克制驱逐它）、有杀戮、有畏惧、有爱慕、有喜悦、有厌恶、有死亡、有逃跑、有停留、有消灭，因此在用于对治时，各有具体的条例。
《仙经》说：使用禁法有六种方法，一是牙齿禁，意念引导气到达牙齿；二是营目禁，睁开一只眼睛闭上另一只眼睛；三是意想禁，集中意念去想象疾病消除；四是捻目禁，据说手上有代表十五日的符号（注：此处原文可能有误或指特定手势/符号）；五是气道禁，即吹、呼、呵、嘘、嘻五种呼吸吐纳法；六是存神禁，存想诸神存在，并通过饮食醮祭来感召天界灵气降临，也就是鸣天鼓和叩齿的方法。
凡是为人请疗疾病，出门三步后念咒说：“天杀黄黄，地杀正方，千鬼万神，谁敢隐藏？飞步一及，百鬼灭亡。急急如律令。”
如果到了主人家，应当先解除秽气，即施行“五龙水法”，手持水碗念咒说：“东方青龙含水来，南方赤龙含水来，西方白龙含水来，北方黑龙含水来，中央黄龙含水来。五方五龙吐水淹没杀灭邪鬼，急急如律令。”念完后，叩齿三百遍。
接着念咒说：“神水解除天秽、地秽、生秽、死秽、人秽、鬼秽、身秽、病患之秽，迅速除去，立刻令其清净，急急如律令。”然后三嘘三叱，用刀向右搅拌三次，用右脚脚跟跺地三下，含一口水向四方喷洒，并喷在病患患处，使其完全清洁，然后按照法术存想神灵施行禁法。再次将气存想到牙齿，让气停留并闭上一只眼睛，意念去除后即做捻目动作。然后用存想七星在头顶，存想青龙、白虎、朱雀、玄武前来护身，存想大神在前后五星，存想在腹内，呼气时存想气息如云，击打病灶处使其像缓慢行走一样消散。行步遵循乾坤法则，如此施行，外邪就不会侵入五脏，神明自然通达。这一切都必须审慎对待，万无一失。
又有另一种方法：想要前往病患家中，应当存想，作白虎吐火之状，焚烧病患家的屋舍，使其荡然无存。又作龙舔舐病患身体肌肉直至尽净。然后再作充满润泽之象，随后用急气去治疗它。想要击打物体，一一都是这样。这能使施行禁法者神明与万物相通，都有神奇效验，必须精心审慎。如果是唾治热病，用冷气吹它十四次（二七），然后施行禁法。如果是唾治冷病，用热气呵它十四次（二七），然后施行禁法，唾三次之后施行禁法，禁法结束后再唾三次才停止。
《仙经》说：接受符箓禁法同此道理，首先应当修身洁己，安魂定魄，口不妄言，洁净斋戒一百天，可以成就神仙之道，避开逆乱恶气，消除灾祸吉祥（注：此处‘灾祥’可能指灾异或吉凶之事，结合语境应指消除灾祸），可以长生不老。
Translation:
It is said that the general principle for using incantations (Jin) is that when reciting the incantation text, one must absolutely not make a sound aloud; it should only be audible to one's own ears. If others hear the咒 (curse/incantation), the Jin method will fail, and its practice will be of no benefit. One must be extremely cautious. When receiving the Jin, one must not let any person or livestock see it; if seen, it will not work. During the reception of the method, the knives and water basins used must never have been in contact with wine, meat, or the Five Pungent Spices (Wu Xin).
The *Shenxian Jing* (Classic of Immortals) states: For counter-treatment Jin, all diseases are treated by overcoming like with like.
When encountering water-related difficulties, use Earth Qi to overcome them; when encountering Earth-related difficulties, use Wood Qi to overcome them; when encountering weapon/danger difficulties, use Yang Essence Qi to overcome them; when encountering ghost/spirit difficulties, use Tao Soup (Peach Decoction) to overcome them; when encountering tiger difficulties, use the Qi of the Five Constants to overcome them. For the counter-treatment of all diseases using like-with-like principles, whether holding a knife, peach branch, fire, mirror, water, rope, medicine, talisman, halberd, bow, arrow, crossbow, food, sitting posture, powder, intention, deity, imagination, Qi, scroll, stone, earth, salt, banner, fat, meat, blood, face/expression, metal, jade, or seal—all these methods are used to suppress through Jin. The required Jin methods involve petitioning,告 (informing), sacrificing, harming (good deities are retained through food sacrifices; evil ghosts are suppressed and driven away), killing, fearing, loving, rejoicing, hating, dying, fleeing, staying, and extinguishing. Therefore, when used for counter-treatment, each has specific regulations.
The *Xian Jing* (Immortal Classic) states: There are six methods of using Jin: 1. Tooth Jin: Intention guides Qi to the teeth. 2. Eye Regulation Jin: Open one eye and close the other. 3. Intentional Imagination Jin: Focus intention to imagine diseases being eliminated. 4. Pinching Eye Jin: Refers to having a symbol representing fifteen days on the hand. 5. Qi Channel Jin: Refers to the five breathing sounds: Chui (Blow), Hu (Exhale), He (Groan), Xu (Whistle), Xi (Laugh). 6. Deity Visualization Jin: Visualize various deities present, and through food offerings and rituals, attract spiritual energy from heaven. This also refers to ringing the heavenly drum and clicking the teeth.
Whenever seeking treatment for someone, after taking three steps out the door, recite the incantation: "Heaven kills Huang Huang, Earth kills Zheng Fang, thousands of ghosts and ten thousand gods, who dares to hide? Flying steps reach instantly, hundred ghosts perish. Execute immediately as per law."
Upon arriving at the host's home, one must first remove impurities by performing the "Five Dragons Water Method," holding a water bowl and reciting: "Eastern Azure Dragon bring water, Southern Red Dragon bring water, Western White Dragon bring water, Northern Black Dragon bring water, Central Yellow Dragon bring water. Five directions' five dragons spit water to drown and kill evil ghosts. Execute immediately as per law." After finishing, click the teeth three hundred times.
Then recite the incantation: "Divine water removes Heaven's impurity, Earth's impurity, Life's impurity, Death's impurity, Human impurity, Ghost impurity, Body impurity, Patient's impurity. Remove them quickly, make them pure immediately. Execute immediately as per law." Then perform three Xu (whistling exhalations) and three Chi (scolding commands), stir rightward with the knife three times, stomp the ground three times with the right heel, hold water in the mouth and spray it in four directions, and spray it onto the patient's affected area, ensuring complete cleanliness. Then, according to the method, visualize deities and perform Jin. Again, guide Qi to the teeth, let it stay, close one eye, and after removing intention, perform the pinching eye action. Then visualize the Seven Stars above the head, visualize Azure Dragon, White Tiger, Vermilion Bird, and Black Tortoise protecting the body, visualize great deities in the front and back with five stars, visualize within the abdomen, exhale while visualizing Qi like clouds, strike the affected area so it moves slowly. Walk following the laws of Qian and Kun. By practicing thus, external evils will not enter the five Zang organs, and divine clarity will naturally flow. All this requires careful scrutiny to ensure no mistakes.
Another method: When intending to go to a patient's house, one must visualize making a White Tiger spit fire, burning the patient's house until nothing remains. Also visualize a dragon licking the patient's flesh until clean. Then visualize replenishment and luster, and subsequently treat with urgent Qi. To strike objects, proceed exactly as described. This allows the practitioner of Jin to communicate with spirits and all things, yielding miraculous effects. It must be done with precision and care. If spitting treats heat diseases, blow cold Qi fourteen times (two sevens), then perform Jin. If spitting treats cold diseases, blow warm Qi fourteen times (two sevens), then perform Jin. After spitting three times, perform Jin; after Jin is finished, spit three more times before stopping.
The *Xian Jing* states: Receiving talismans and Jin follows the same method. First, cultivate oneself and keep pure, stabilize the soul and fix the spirit, speak not frivolously, observe a pure fast for one hundred days. One can achieve immortality, avoid adverse and evil energies, eliminate disasters, and attain longevity.
