《太上玄镜》曰∶纯阳上升者谓之气,纯阴下降者谓之液,气液相交于骨脉之间谓之
髓,相交于膀胱之外谓之精。心气在肝,肝精不固,目眩无光;心气在肺,肺精不固,肌
肉瘦弱;心气在肾,肾精不固,神气减少;心气在脾,脾精不固,齿发浮落。五脏之中,
肾为精枢,心为气管,真精在肾,余精自还、下曰∶真气在心,余气自归元府。
吕祖师曰∶精养灵根气养神,此真真外更无真,神仙不肯分明说,迷了千千万万人。
又曰∶二八佳人体似酥,腰间佩剑斩愚夫,虽然不见人头落,暗里教君骨髓枯。
彭祖曰∶可惜可惜真可惜,自家有宝人不识,将来送于粉骷髅,却向人间买秋石。
又仙真曰∶尾闾不禁沧海竭,九转神丹都谩说,总有斑龙顶上珠,难补玉堂关下阙。
寥阳师曰∶夫人身中元气,日日发生,只为不知保养,故被二邪侵削。何为二邪?
风寒暑湿之邪,喜怒哀乐之邪,日夜攻伐,所以元气耗竭,遂至于亡。真人知道保命,在留
得元气住,故敢人升元精、保元气,合做一处,至坚至固,不耗不散,禁得二邪侵伐,
然后能长生久视。
施肩吾曰∶气是添年药,心为使气神,能知行气主,便可作仙人。
谭紫霄曰∶神犹母也,气犹子也,以神及气,如以母召
子,孰敢不至?
刘赤脚曰∶神气自然,如子母相爱,只为尘情相隔,不能相见,若去了一分尘情,即
有一分升降。
李清庵曰∶心归虚寂,身入无为,动静俱忘,到这里精自化气,气自然化神,神自然还
虚。
丘长春曰∶修行须要三全。戒思虑,神全;戒言语,气全;戒色欲,精全。又要三满∶
神满,不思睡∶气满,不思食;精满,不思欲。
或问∶前修格言既闻命矣,下手之工夫若何?曰∶顾人之用力何如耳。吾之所以谆谆于
惜精者,盖以色心易动,欲火难禁,情念一兴,精离肾府,或随溺而出,或流溢于外,岂必交
感而后泄哉?故曰∶有感于中,必摇其精。此古人避色如避仇之说也。是当于欲动之时,急
转念头,即行调息之法,呼接天根,吸接地根,内有所事,则欲亦可回,始虽强制,久则自然
。如纵其淫泄,则百媚红颜,断送万万千千少年的性命;一堆黄土,埋藏多多少少盖世英雄。
兴言及此,宁不寒心?是以圣贤专为后嗣计,自有天然之节制,何也?男子十六而精通,二十
以前两日复,三十以后十日复,四十以后月复,五十以后三月复,六十以后七月复,故曰六十
闭户,乃时加爱养,以为寿命之本也。否则,虽勤吐纳导引服饵药石何益哉?唯能保守此精,则
气壮神全,长生可渐致矣。或曰∶人有一饮而倾四坐,日拥侠邪二八以为乐,乃年老而未艾,有
疏仪狄,屏骊姬,以二戒为竞,竞未艾而艾,此曷以故?曰∶是系于人之所禀不同耳,然鲜有
不伤于所恃者,唯能爱生可延生也。
《太上玄镜》说:纯粹上升的阳气称为气,纯粹下降的阴气称为液,气和液在骨脉之间交汇称为髓,在膀胱之外交汇称为精。心气若位于肝,而肝的精气不固守,则会出现目眩、目光无神;心气若位于肺,而肺的精气不固守,则会出现肌肉消瘦虚弱;心气若位于肾,而肾的精气不固守,则会导致神气减少;心气若位于脾,而脾的精气不固守,则会导致牙齿松动脱落、头发漂浮易落。在五脏之中,肾脏是精气的枢纽,心脏是气机的通道,真正的精气藏于肾中,其余的精气自然回归(此处原文似有脱漏或特定语境,意指精气归根);下文说:真气在心,其余的气自然归向元府(丹田/下焦)。
吕祖师说:用精来滋养灵根,用气来滋养精神,这真是真中之真,除此之外再无更真的了。神仙不肯把道理讲得明白,导致千千万万的人迷失了方向。
又说:十六岁青春少女体态如酥软般美好,但腰间佩戴利剑斩断愚昧之人的性命,虽然看不见人头落地,却在暗中让人骨髓枯竭。
彭祖说:可惜啊可惜,真是可惜,自己拥有珍宝却无人识得,反而将其送给粉骷髅(指死亡),却到人间去买秋石(一种中药,此处喻指错误的补益之物)。
又有仙真说:尾闾关如果不加禁固,就像沧海之水枯竭一样(精气流失不止),九转神丹都空谈无用,即使头顶上有斑龙珠(喻指珍贵的内丹或宝物),也难以填补玉堂关下的缺失(指下元亏损)。
寥阳师说:人体中的元气,每天都在发生,只因为不知道保养,所以被两种邪气侵扰削弱。什么是两种邪气?风寒暑湿的外邪,以及喜怒哀乐的内邪,日夜攻伐身体,导致元气耗竭,最终走向灭亡。真人知道如何保命,在于留住元气,所以主张提升元精、保护元气,使二者合为一体,达到极其坚固的状态,不消耗不散失,能够抵御两种邪气的侵扰,然后才能长生久视。
施肩吾说:气是增添寿命的药物,心是驾驭气的神志,如果能懂得行气的主旨,就可以成为仙人。
谭紫霄说:神好比母亲,气好比儿子,用神来招唤气,就像母亲召唤儿子,谁敢不来呢?
刘赤脚说:神和气本是自然的,如同母子相爱,只因为尘世情感的阻隔,不能相见,如果去掉一分尘世情感,就有一分的升降(气机通畅)。
李清庵说:心归于虚空寂静,身体进入无为境界,动与静都遗忘,到了这个地步,精自然化为气,气自然化为神,神自然返还虚空。
丘长春说:修行需要做到“三全”。戒除思虑,神就圆满;戒除言语,气就圆满;戒除色欲,精就圆满。还要做到“三满”:神满,就不想睡觉;气满,就不想进食;精满,就不想性欲。
有人问:前代修行的格言既然已经听明白了,下手修行的工夫该怎么做呢?回答说:只看人用力的程度如何罢了。我之所以谆谆告诫珍惜精气,是因为色心容易动摇,欲火难以禁止,情念一起,精气就会离开肾府,或者随着小便排出,或者流溢体外,难道一定要性交之后才泄出吗?所以说:内心受到诱惑,必然会摇动精气。这就是古人避色如避仇的说法。应当在欲望萌动之时,立即转变念头,随即施行调息的方法,呼气连接天根,吸气连接地根,内心有所专注做事,那么欲望也可以挽回,起初虽然是强制控制,久而久之就会变得自然。如果放纵淫欲泄精,那么百媚红颜,断送了成千上万少年的性命;一堆黄土,埋藏着无数盖世英雄。想到这些,怎能不令人心寒?因此圣贤专门为后代子孙打算,自有天然的节制,为什么呢?男子十六岁时精通(精气成熟),二十岁以前两天恢复一次,三十岁以后十天恢复一次,四十岁以后一个月恢复一次,五十岁以后三个月恢复一次,六十岁以后七个月恢复一次,所以说六十岁应当闭门谢客,时常加以爱养,作为寿命的根本。否则,虽然勤于吐纳导引、服用药物又有什么益处呢?只有能保守住这个精,那么气壮神全,长生就可以逐渐达到了。有人说:有的人一饮而尽让四座皆醉,每天拥抱着十六岁的佳人为乐,却年老而未衰败,疏远仪狄(杜康/酒神),屏退骊姬(美色),以二戒(酒色)为竞争,竞争未止而衰老不止,这是什么原因呢?回答说:这是取决于人所禀受的体质不同罢了,然而很少有不被自己所倚仗(年轻/天赋)所伤害的,只有珍爱生命才能延长生命。
The *Taishang Xuanjing* (Supreme Profane Mirror) states: Pure yang that ascends is called Qi (vital energy), and pure yin that descends is called Ye (body fluids). When Qi and Ye intersect between the bone meridians, it is called Sui (marrow); when they intersect outside the bladder, it is called Jing (essence). If Heart Qi resides in the Liver, and Liver Jing is not secure, one experiences dizziness and lackluster eyes; if Heart Qi resides in the Lungs, and Lung Jing is not secure, muscles become thin and weak; if Heart Qi resides in the Kidneys, and Kidney Jing is not secure, Shen (spirit) and Qi diminish; if Heart Qi resides in the Spleen, and Spleen Jing is not secure, teeth loosen and fall out, and hair becomes brittle and falls. Among the Five Viscera, the Kidney is the pivot of Jing, and the Heart is the channel of Qi. True Jing resides in the Kidney, while other Jing naturally returns; as stated below: True Qi resides in the Heart, and other Qi naturally returns to the Yuanfu (Primordial Mansion/Dantian).
Master Lü said: "Nourish the spiritual root with Jing, nourish the spirit with Qi; this is the truest truth, beyond which there is nothing more true. Immortals do not explain it clearly, causing thousands upon thousands of people to be lost."
He also said: "A sixteen-year-old beauty is soft as curd, but a sword at her waist cuts off the lives of fools. Although no heads are seen falling, secretly she causes your marrow to dry up."
Peng Zu said: "Pity, pity, truly pity. You possess treasures within but fail to recognize them, instead giving them to powder skeletons (death), and seeking autumn stone (a mineral drug) in the human world."
Another immortal stated: "If the Weilu gate (tailbone area, a key point for conserving essence) is not controlled, the ocean will dry up. The nine-turn elixir is merely talk. Even if you have the Banlong pearl on top of your head, it cannot fill the deficiency below the Yutang gate (lower abdomen/kidney region)."
Master Liaoyang said: "The primordial Qi in the human body arises daily. However, because people do not know how to preserve it, it is invaded and depleted by two types of evil influences. What are these two evils? They are the external evils of wind, cold, summer-heat, and dampness, and the internal evils of joy, anger, sorrow, and happiness. These attack day and night, causing primordial Qi to exhaust until death ensues. A true person knows how to preserve life by retaining primordial Qi. Therefore, they advocate raising Yuanjing and protecting Yuanqi, combining them into one solid entity that does not dissipate or scatter, resisting invasion by the two evils, thereby achieving longevity."
Shi Jiongwu said: "Qi is the medicine that adds years; the Heart is the deity that directs Qi. If one understands the master of Qi circulation, one can become an immortal."
Tan Zixiao said: "Shen is like a mother, and Qi is like a son. Using Shen to summon Qi is like a mother calling her son; who would dare not come?"
Liu Chijiao said: "Shen and Qi are natural, loving each other like mother and child. Only worldly emotions separate them, preventing reunion. Remove one part of worldly emotion, and there is one part of free ascent and descent (Qi movement)."
Li Qing'an said: "When the Heart returns to emptiness and silence, and the body enters non-action, forgetting both motion and stillness, Jing naturally transforms into Qi, Qi naturally transforms into Shen, and Shen naturally returns to emptiness."
Qiu Changchun said: "Cultivation requires the 'Three Completions': Guard against overthinking to complete Shen; guard against excessive speech to complete Qi; guard against lust to complete Jing. It also requires the 'Three Fullnesses': When Shen is full, one has no desire for sleep; when Qi is full, one has no desire for food; when Jing is full, one has no desire for sexual activity."
Someone asked: "Having heard the maxims of previous cultivators, what is the method for beginning practice?" The answer was: "It depends entirely on the effort exerted by the individual. I earnestly advise cherishing Jing because the mind of lust is easily stirred, and the fire of desire is hard to suppress. Once emotional thoughts arise, Jing leaves the Kidney mansion, either exiting with urine or leaking externally. Does it require intercourse to leak? Thus it is said: 'Being moved internally inevitably shakes the Jing.' This is why ancients avoided women as they would avoid enemies. At the moment desire stirs, one must immediately shift one's thoughts and employ breathing regulation methods: exhaling connects to the Heavenly Root, inhaling connects to the Earthly Root. With internal focus, desire can be turned back. Initially forced, it becomes natural over time. If one indulges in lewd leakage, countless beautiful faces will ruin the lives of thousands of youths; piles of yellow earth will bury many heroes of the world. Speaking of this, does it not chill the heart? Therefore, sages plan for descendants with natural restraint. Why? Men reach seminal emission maturity at sixteen. Before twenty, recovery takes two days; after thirty, ten days; after forty, one month; after fifty, three months; after sixty, seven months. Thus, it is said that at sixty, one should close the door and cultivate carefully, as this is the foundation of lifespan. Otherwise, what good are diligent tu-na (breathing exercises), daoyin (guiding and pulling), and medicinal herbs? Only by conserving this Jing can Qi be strong and Shen complete, gradually leading to longevity."
Someone said: "There are those who drink enough to intoxicate four guests, embracing sixteen-year-old beauties for pleasure daily, yet remain vigorous in old age. They shun Yi Di (wine) and dismiss Li Ji (beauty), competing in abstinence from these two, yet their vitality does not cease. Why?" The answer was: "This depends on the different constitutions individuals are born with. However, few escape harm from relying on their innate advantages. Only by loving life can one extend life."
