《消魔经》云∶耳欲得数按抑，左右令无数，使人聪彻。所谓营治城廓，名书皇籍。
天鼓者，耳中声也。以两手心紧按耳门，以指击其脑户，常欲其声壮盛，相续不散。一日三
操，有益于下丹田。或声散不续，无壮盛者，即元气不集，宜整之。
《真诰》云∶面者神之庭，发者脑之华。心悲即面焦，脑减则发素。《太素经》云∶一面
之上，常欲得两手摩拭之使热，高下随形，皆使极匝，令人面有光泽，皱斑不生。行之五年，
色如少女。所谓山泽通气，常盈不没。又云∶勤而行之，手不离面，乃佳。
《真诰》云∶顺手摩发，如理栉之状，使发不白。以两
手乘额上，谓之手朝三元，固脑坚发之道也。头四面，以手乘之，顺发就结，唯令多也。
《黄庭经》云∶一面之神宗泥丸，泥丸九真皆有房，方圆一寸处其中。
《黄庭经》云∶两部水王对生门。生门者脐也。闭内气，鼓小腹令满，以手摩一周天。
此在口诀。气海与肾相连，属壬癸。水性就下，水归于海，不能独升，必以阳配。阳既下临，阴
即上报。故化为云雾，蒸为甘雨，润泽枯槁，百骸九窍，无所不达。烟萝子所谓火逼水、云 、
五行相连会成功。启玄子亦云∶无出则不入，无降则无升。
此在口诀。世人不蒙师授，多将心火为火。火属神，且内中垆鼎在心，下得心火为火，其火
在鼎上。《千经万论》言火从下发，未闻火从上来。《周易》卦有水火既济，是上水下火，火自脐
下起，水在鼎中生。故曰上水下火。诀云∶但从
山头取水，海底起火，重阳中取汞，重阴中取铅。故行有路，取有时，世人窃用其道，不受口诀，
反受其病。通真子歌云∶解接无根木，能挑海底灯。古歌亦曰∶还丹修炼本无形，元火烹来即渐成。
须信神仙路咫尺，朗然飞步上青冥。
《消魔经》说：耳朵需要经常按压揉捏，左右交替进行，次数不限，这样能使人听力敏锐清晰。这被称为“营治城廓”，意指保养身体如同修筑城墙，名字可录入仙籍（获得长寿或成仙的资格）。
所谓“天鼓”，是指耳中的声响。用双手掌心紧紧按住耳门，用手指敲击后脑勺部位（风府穴附近），要常使声音宏大旺盛，连续不断。每天练习三次，对下丹田有益。如果声音散乱不连续，或者不够宏大旺盛，说明元气没有聚集，应当调整方法使其凝聚。
《真诰》说：面部是精神的外在表现场所，头发是脑髓精华的外在体现。内心悲伤会导致面色枯槁，脑髓亏损则头发变白。《太素经》说：在面部之上，经常要用双手摩擦擦拭，使其发热，高低起伏顺应面部轮廓，都要做到充分周全，这样能使面部有光泽，不生皱纹斑点。坚持做五年，面色会像少女一样红润。这被称为“山泽通气”，指体内气机充盈而不枯竭。又说：勤奋地练习，手不要离开面部，效果才好。
《真诰》说：顺着方向按摩头发，就像梳理头发放梳子一样的动作，可以使头发不变白。将双手放在额头上方，称为“手朝三元”，这是坚固脑髓、强健头发的方法。用手按摩头的四周，顺着发丝的方向梳理，只追求数量多。《黄庭经》说：面部的神灵以泥丸宫为宗主，泥丸宫中有九位真人各有居所，位于方圆一寸的中心位置。
《黄庭经》说：两部水王（肾与膀胱）对着生门。生门就是肚脐。闭守体内的气息，鼓动小腹使其充满，然后用手掌按摩腹部一周天。
这些内容属于口传秘诀。气海穴与肾脏相连，五行属壬癸（水）。水性向下流动，水流归入大海，不能独自上升，必须配合阳气。阳气既然下到下面，阴气就会向上回报。因此化为云雾，蒸腾为甘雨，滋润干枯的身体，使全身骨骼和孔窍无处不到。烟萝子所说的“火逼水”、“云行雨施”、“五行相连会成功”。启玄子也说：没有下降就没有上升，没有退出就没有进入。
这些内容属于口传秘诀。世人如果没有得到师父传授，大多把心火当作真火。火对应神志，且人体内部的炉鼎位于心脏，如果把心火当作真火，那么火就在鼎的上面。《千经万论》说火是从下面升起的，没听说过火是从上面下来的。《周易》卦象中有“水火既济”，指的是上水下火，火从脐下升起，水在鼎中生成。所以说是上水下火。口诀说：只是从山头取水（取阴），从海底起火（取阳），在重阳之中取汞，在重阴之中取铅。所以修炼有路径，采集有时机，世人私下使用这种方法，却不接受正确的口诀指导，反而遭受疾病伤害。通真子的歌谣说：解开无根木的连接，能挑亮海底的灯。古歌也说：还丹修炼本来无形，元火烹炼自然渐渐成就。必须相信神仙之路近在咫尺，明朗地飞步登上青天。
The *Xiao Mo Jing* (Scripture on Extinguishing Demons) states: The ears should be frequently pressed and kneaded, alternating left and right without limit, to make one's hearing sharp and clear. This is called "Ying Zhi Cheng Guo" (Managing and Repairing the City Walls), implying that by preserving the body like fortifying a city, one's name may be recorded in the Imperial Register of Immortals.
What is called "Tian Gu" (Heavenly Drum) refers to the sounds within the ears. Press the ear gates tightly with both palms, and strike the back of the head (near Fengfu GV16) with fingers. One should constantly aim for the sound to be loud and vigorous, continuous and unbroken. Practicing this three times a day benefits the Lower Dantian. If the sound is scattered and discontinuous, or lacks vigor, it indicates that Yuan Qi (Primordial Qi) has not gathered; one should adjust the method to consolidate it.
The *Zhen Gao* (True Records) states: The face is the courtyard of the Spirit (Shen); hair is the brilliance of the brain. Sorrow causes the face to wither; depletion of the brain causes hair to turn white. The *Tai Su Jing* (Classic of Great Simplicity) states: On the surface of the face, one should frequently rub and wipe it with both hands until it becomes hot. Follow the contours high and low, ensuring thorough coverage, so that the face gains luster and wrinkles do not form. Practicing this for five years makes the complexion resemble that of a young girl. This is referred to as "Shan Ze Tong Qi" (Mountain and Marsh Ventilate Each Other), indicating constant fullness and non-depletion. It further states: Practice diligently, keeping hands close to the face, which is optimal.
The *Zhen Gao* states: Massage the hair along its direction, as if combing it, to prevent hair from turning white. Place both hands above the forehead, termed "Hands Facing the Three Primaries" (San Yuan), which is the way to solidify the brain and strengthen the hair. Use hands to massage all four sides of the head, following the direction of hair growth towards knots, aiming for repetition. The *Huang Ting Jing* (Yellow Court Scripture) states: The deity of the face takes Ni Wan Palace (Mud Pill Palace) as its master. Within Ni Wan Palace, there are nine True Ones, each having their own chamber, located in the center of a square inch area.
The *Huang Ting Jing* states: The Two Water Kings (Kidneys and Bladder) face the Gate of Life (Sheng Men). The Gate of Life is the umbilicus. Retain internal Qi, distend the lower abdomen until full, and then rub the abdomen with hands for one cycle of Heaven (a full circular motion).
These points belong to oral instructions. Qihai (Sea of Qi) connects with the Kidneys and belongs to Ren and Gui (Water element in Heavenly Stems). Water nature flows downward; water returns to the sea but cannot rise alone; it must be paired with Yang. Once Yang descends below, Yin reports upward. Thus, they transform into clouds and mist, vaporize into sweet rain, moistening dryness, reaching every bone and orifice. Yanluo Zi said: "Fire forces Water," "Clouds move and Rain is poured," "Five Elements connect and achieve success." Qixuan Zi also said: "Without exiting, there is no entering; without descending, there is no ascending."
These points belong to oral instructions. People in the world, lacking transmission from a master, often mistake Heart Fire for the true fire. Fire corresponds to Shen (Spirit). The internal furnace and tripod are located in the heart. If one uses Heart Fire as the fire, the fire is above the tripod. The *Qian Jing Wan Lun* (Thousand Scriptures and Myriad Discourses) states that fire rises from below; it is unheard of for fire to come from above. The hexagram *Shui Huo Ji Ji* (Water over Fire - Completion) in the *I Ching* depicts upper water and lower fire, where fire rises from below the navel, and water generates within the tripod. Hence, it is said: Upper water, lower fire. The formula states: Only take water from the mountain peak (Yang seeking Yin), ignite fire from the sea bottom (Yin seeking Yang); extract Mercury from Heavy Yang, and Lead from Heavy Yin. Thus, there is a path for practice, and timing for extraction. Those who secretly use this method without receiving the correct oral instructions suffer illness instead. Tongzhen Zi's song says: "Untie the rootless wood, able to light the lamp at the sea bottom." An ancient song also says: "The refinement of the Elixir is originally formless; cooked by Primordial Fire, it gradually forms." One must believe that the path of immortals is but a step away; clearly and swiftly, ascend to the blue heavens.
