道以精为宝，施之则生人，留之则生身。生身则求度在仙位，生人则功遂而身退，功遂而身退，则
陷欲以为剧。何况妄施而废弃，损不觉多，故疲劳而命堕。天地有阴阳，阴阳，人所贵，贵之合于道，
但当慎无费。彭祖曰∶上士别床，中士异被，服药千裹，不如独卧。色使目盲，声使耳聋，味使口爽。
苟能节室其道，适抑扬其通塞者，可以增寿。一日之忌，暮食无饱（夜饱食眠，损一日之寿）；一月之忌，
暮饮无醉（夜醉卧，损一月之寿）；一岁之忌，暮须远内（一交损一岁之寿，养之不复）；终
身之忌，暮须护气（暮卧，习闭口，开口失气。又邪从口入）。采女问彭祖曰∶人年六十，当闭精
守一，为可尔否？彭祖曰∶不然。男不欲无女，无女则意动，意动则神劳，神劳则损寿。若念真正无可
思而大佳，然而万无一焉。有强郁闭之，难持易失，使人漏精尿浊，以致鬼交之病。又欲令气未感动，
阳道垂弱，欲以御女者，先摇动，令其强起，但徐徐接之，令得阴气。阴气推之，须臾自强，强而用
之，务令迟疏，精动而止。闭精缓息，瞑目偃卧，导引身体，更复可御他女。欲一动则辄易人，易人可
长生。若御一女，阴气既微，为益亦少。又阳道法火，阴道法水，水能制火，阴亦消阳。久用不止，
阴气吸阳，阳则转损，所得不补所失。但能御十二女子而不复泄者，令人老有美色。若御九十三女而不泄
者，年万岁。凡精少则病，精尽则死，不可不忍，不可不慎。数交而时一泄，精气随长，不能使人虚损。
若数交接则泻精，精不得长益，行精尽矣。在家所以数数交接者，一动不泻，则赢得一泻之精，减即不能
数交接。但一月辄再泻精，精气亦自然生长。但迟微不能速起，不如数交接不泻之速也（采女者，少得
道，知养性，年一百七十岁视如十五。殷王奉事之年，问道于彭祖也）。彭祖曰∶奸淫所以使人不寿者，非
是鬼神所为也，直由用意俗猥，精动欲泄，务副彼心，竭力无厌，不以相生，反以相害。或惊狂消渴，或
癫痴恶疮，为失精之故。但施泻，辄导引，以补其处，不尔，血脉髓脑日捐，风湿犯之则生疾病。由俗人
不知补泻之宜故也。彭祖曰∶凡男不可无女，女不可无男。若孤独而思交接者，损人寿；生百病，鬼魅
因之。共交失精，而一当百。若欲求子，令子长命、贤明、富贵，取月宿日施精大佳（月宿日，直录之
于后）。天志曰∶人生俱含五常，形法复同而有尊卑贵贱者，皆由父母合八星阴阳。阴阳不得其时，
中也；不
合宿，或得其时，人中上也；不合宿，不得其时，则为凡夫矣。合宿交会者，非生子富贵，亦利己身，
大吉之兆（八星者，室、参、井、鬼、柳、张、心、斗，月宿在此星，可以合阴阳求子）。月二日、三
日、五日、九日、二十日，此是王相生气日，交会各五倍，血气不伤，令人无病。仍以王相日半夜后鸡
鸣前，徐徐弄玉泉，饮玉浆戏之。若合，用春甲寅乙卯、夏丙午丁未、秋庚申辛酉、冬壬子癸亥，与上
件月宿日合者，尤益佳。若欲求子，待女人月经绝后一日、三日、五日，择中王相日，以气生时，夜半
之后，乃施精。有子皆男，必有寿贤明。其王相日，谓春甲乙、夏丙丁、秋庚辛、冬壬癸。凡养生，要
在于爱精。若能一月再施精，一岁二十四气施精，皆得寿百二十岁。若加药饵，则可长生，所患人年少
时，不知道，知道亦不能信行；至老乃始知道，便已晚矣，病难养也。虽晚而能自保，犹得延年益寿。
若少壮而能行道者，仙可冀矣。《仙经》曰∶男女俱仙之道，深内勿动精，思脐中赤色大如鸡子，乃徐
徐出入，精动便退。一旦一夕，可数十为之，令人益寿。男女各息，意共存之，唯须猛念。道人刘京云∶
春三日一施精，夏及秋一月再施精，冬常闭精勿施。夫天道，冬藏其阳，人能法之，故得长生。冬一施，
当春百。蒯道人言∶人年六十，盒饭都绝房内，若能接而不施精者，可御女耳。若自度不办者，都远之
为上。服药百种，不如此事可得久年也。道林云∶命本者，生命之根本，决在此道，虽服大药及呼吸
导引，备修万道而不知命之根本。根本者，如树木，但有繁枝茂叶而无根本，不得久活也。命本者，房中
之事也。故圣人云∶欲得长生，当由所生。房中之事，能生人，能杀人。譬如水火，知用之者，可以养
生，不能用之者，
立可死矣。交接尤禁醉饱，大忌，损人百倍。欲小便忍之以交接，令人得淋病或小便难、茎中痛、小腹强。
大恚怒后交接，令人发痈疽。道机房中禁忌∶日月晦朔、上下弦、望、日月蚀、大风、恶雨、地动、雷
电、霹雳、大寒暑、春夏秋冬节变之日、送迎五日之中，不行。阴阳本命、行年月日忌禁之尤重（阴阳交
错，不可合，损血气，泻正纳邪，所伤正气甚矣，戒之）。新沐头、新行疲倦、大喜怒，皆不可行房室。
彭祖曰∶消息之情，不可不知也，又须当避大寒、大热、大风、大雨、大雪、日月蚀、地动、雷震，
此是天忌也。醉饱、喜怒、忧愁、悲哀、恐惧，此人忌也。山川、神 、社稷、井灶之处，此为地忌也。
既避此三忌，又有吉日，春甲乙、夏丙丁、秋庚辛、冬壬癸、四季之月戊己，皆王相之日也。宜用嘉会，
令人长生，有子必寿。其犯此忌，既致疾，生子亦凶夭短命。老子曰∶还精补脑，可得不老矣。《子都
经》曰∶施泻之法，须当弱入强出（何谓弱入强出，纳玉茎于琴弦麦齿之间，及洪大便出之，弱纳之，
是谓弱入强出。消息之，令满八十动，则阳数备即为妙也）。老子曰∶弱入强出，知生之术；强入弱出，
良命乃卒。此之谓也。
道以精液为宝贵之物，施泄精液可以生育人类，保留精液可以滋养自身。滋养自身则追求达到仙人的境界；生育人类则功业成就后便退隐，功业成就后若再退隐（指沉溺于欲望），就会陷入欲望之中而变得剧烈。更何况胡乱施泄且废弃养生之道，损耗不知不觉间增多，因此导致疲劳而寿命坠落。天地有阴和阳，阴阳是人所尊贵的，尊贵它就要合乎道，只应当谨慎不要耗费。彭祖说：上等的人分床睡，中等的人分被睡，服用千副药方，不如独自睡觉。美色使人眼盲，声音使人耳聋，滋味使人口舌败坏。如果能够节制房事之道，适当调节其通畅与闭塞，就可以增加寿命。一天的禁忌，晚上吃饭不要吃饱（夜里吃饱就睡，损害一天的寿命）；一个月的禁忌，晚上喝酒不要喝醉（夜里醉酒躺卧，损害一个月的寿命）；一年的禁忌，晚上必须远离房事（一次性交损害一年的寿命，养护也补不回来）；终身的禁忌，晚上必须护住元气（晚上睡觉，习惯闭口，开口会流失气。另外邪气从口进入）。采女问彭祖说：人到了六十岁，应当封闭精液守住一窍，这样可以吗？彭祖说：不对。男人不想没有女人，没有女人则心意动摇，心意动摇则精神劳累，精神劳累则损害寿命。如果念头纯正没有什么可思虑的当然很好，然而万中无一。如果有强行郁结封闭的，难以坚持容易丧失，使人漏精尿浊，以致产生鬼交的病。又想要让气还没有感动，阳道垂弱，想要用御女之法的人，先摇动身体，让它强起，只是慢慢接触它，让它得到阴气。阴气推动它，一会儿自然强壮，强壮了再使用它，务必令性交迟缓稀疏，精液欲动时就停止。闭住精液放缓呼吸，闭上眼睛仰卧，导引身体，又可以再御其他女子。想动一次就换一个人，换人可以长生。如果御同一个女子，阴气既然微弱，获益也很少。又阳道效法火，阴道效法水，水能克制火，阴也能消减阳。长久使用不停止，阴气吸走阳气，阳则转而受损，所得不能弥补所失。如果能御十二个女子而不再次泄精的，让人年老仍有美貌。如果御九十三女子而不泄精的，活到一万岁。凡是精液少就会生病，精液耗尽就会死亡，不可以不谨慎，不可以不慎重。多次交合偶尔一次泄精，精气随之生长，不能使人虚损。如果多次交接就泻精，精液不得增长，行精就用尽了。在家之所以频繁交接，是一次不泻，就能赢得一次泻的精液，减少就不能频繁交接。只要一个月两次泻精，精气也自然生长。只是迟缓微弱不能快速勃起，不如多次交接不泻的快速（采女这个人，早年得道，懂得养性，年龄一百七十岁看起来像十五岁。殷王侍奉她的年数，向彭祖问道）。彭祖说：奸淫所以使人不长寿的，并不是鬼神所为，直接是因为用意俗陋猥琐，精液欲动想泄，务必顺从对方的心意，竭力不知满足，不以相生，反而以相害。有的惊恐狂乱消渴，有的癫痴恶疮，都是因失精的缘故。只要施泻，就随即导引，来补益那个地方，不然的话，血脉髓脑每天亏损，风湿侵犯它就产生疾病。因为世俗人不知道补泻的适宜缘故。彭祖说：大凡男人不可没有女人，女人不可没有男人。如果孤独而思念交合，损害人寿命；生出百种病，鬼魅因此而来。共同交合失精，一次抵得上百倍。如果想要求子，让孩子长寿、贤明、富贵，选择月宿日施精非常好（月宿日，直接记录在后面）。天志说：人生都包含五常，形体法则相同而有尊卑贵贱的，都是由父母结合八星阴阳决定的。阴阳不得其时，生在中层；不合宿，或者得其时，生在人中上层；不合宿，不得其时，就是凡人罢了。合宿交会的，不是生子富贵，也有利于己身，是大吉的征兆（八星者，室、参、井、鬼、柳、张、心、斗，月亮宿在这些星，可以合阴阳求子）。二月二日、三日、五日、九日、二十日，这些是王相生气日，交会各五倍，血气不伤，让人无病。仍以王相日半夜后鸡鸣前，慢慢弄玉泉，饮玉浆嬉戏。如果合欢，用春甲寅乙卯、夏丙午丁未、秋庚申辛酉、冬壬子癸亥，与上面提到的月宿日符合的，尤其更加有益。如果想要求子，等待女人月经结束后一日、三日、五日，选择中间的王相日，以气生的时候，夜半之后，才施精。有孩子都是男性，必定长寿贤明。其王相日，谓春甲乙、夏丙丁、秋庚辛、冬壬癸。大凡养生，关键在于爱惜精液。如果能一月两次施精，一年二十四节气施精，都能活到一百二十岁。如果加上药物饵剂，则可以长生，所担忧的是人年少时，不知道道，知道了也不能信行；到了老才开始知道道，就已经晚了，病难调养。虽然晚但能自我保全，还能延年益寿。如果少壮而能行道，仙人是可以期望的了。《仙经》说：男女俱成仙道的，深插入不要动精，想着脐中红色大如鸡蛋，然后慢慢出入，精动就退。一天一夜，可以做几十次，让人益寿。男女各自休息，意念共存，只需要猛念。道人刘京说：春三天一次施精，夏及秋一月两次施精，冬常闭精勿施。夫天道，冬天收藏其阳，人能效法它，所以得以长生。冬天一次施精，相当于春天一百次。蒯道人言：人年六十，应当完全断绝房事，如果能接而不施精的，可以御女罢了。如果自己估计做不到，完全远离为上策。服药百种，不如这件事可以得到久年。道林说：命本，是生命的根本，决定在此道，虽然服大药及呼吸导引，备修万道而不知道命的根本。根本者，如同树木，只有繁枝茂叶而无根本，不能久活。命本，是房中之事。所以圣人云：想要长生，应当由所生。房中之事，能生人，能杀人。譬如水火，知道用的，可以养生，不能用的，立刻死矣。交接尤其禁止醉饱，大忌，损害人百倍。想小便忍之以交接，让人得淋病或小便难、茎中痛、小腹强。大怒后交接，让人发痈疽。道机房中禁忌：日月晦朔、上下弦、望、日月蚀、大风、恶雨、地动、雷电、霹雳、大寒暑、春夏秋冬节变之日、送迎五日之中，不行。阴阳本命、行年月日忌禁之尤重（阴阳交错，不可合，损血气，泻正纳邪，所伤正气甚矣，戒之）。新洗头、新行疲倦、大喜怒，皆不可行房室。彭祖说：消息之情，不可以不知道，又须当避开大寒、大热、大风、大雨、大雪、日月蚀、地动、雷震，这是天忌。醉饱、喜怒、忧愁、悲哀、恐惧，这是人忌。山川、神社稷、井灶之处，这是地忌。既避此三忌，又有吉日，春甲乙、夏丙丁、秋庚辛、冬壬癸、四季之月戊己，都是王相之日。宜用嘉会，让人长生，有子必寿。其犯此忌，既致病，生子亦凶夭短命。老子说：还精补脑，可以得不老矣。《子都经》说：施泻之法，须当弱入强出（何谓弱入强出，纳玉茎于琴弦麦齿之间，及洪大便出之，弱纳之，是谓弱入强出。消息之，令满八十动，则阳数备即为妙也）。老子说：弱入强出，知生之术；强入弱出，良命乃卒。此之谓也。
Dao regards Jing (Essence) as a treasure. Its emission generates humans, while its retention nourishes the self. Nourishing the self leads to seeking the position of an Immortal; generating humans means that once the merit is accomplished, one retreats. If one retreats after accomplishing merit but falls into desire, it becomes intense. How much more so is it to recklessly emit and abandon [health], where damage is unnoticed yet accumulates, leading to fatigue and the fall of life span. Heaven and Earth possess Yin and Yang. Yin and Yang are what humans revere. Revering them must align with Dao; one should be cautious and avoid waste. Peng Zu said: "Superior men sleep in separate beds, average men use separate quilts. Taking a thousand doses of medicine is not as good as sleeping alone." Beauty blinds the eyes, sound deafens the ears, and taste dulls the palate. If one can regulate the way of the bedroom, appropriately balancing openness and closure, longevity can be increased. The taboo for one day: do not eat until full at night (eating until full and then sleeping damages one day's lifespan). The taboo for one month: do not get drunk at night (sleeping while drunk damages one month's lifespan). The taboo for one year: avoid sexual intercourse at night (one act damages one year's lifespan, which cannot be recovered by nurturing). The lifelong taboo: protect Qi at night (when sleeping at night, practice closing the mouth; opening the mouth loses Qi. Furthermore, evil pathogens enter through the mouth). Cai Nu asked Peng Zu: "When a person reaches sixty years old, should they close their Jing and guard the One? Is this correct?" Peng Zu replied: "Incorrect. Men do not wish to be without women. Without women, the mind stirs; when the mind stirs, the Spirit labors; when the Spirit labors, lifespan is damaged. If one's thoughts are pure and devoid of desire, that is excellent, but this happens in ten thousand cases only once. Forcing suppression is difficult to maintain and easily lost, causing leakage of Jing and turbid urine, leading to the disease of 'ghostly intercourse.' Also, if one wishes to engage in sexual intercourse with a woman while the Qi has not yet stirred and the Yang organ is weak, one should first agitate the body to induce erection, then gently engage, allowing the reception of Yin Qi. Pushed by Yin Qi, it will naturally become strong. Once strong, proceed slowly and sparingly. Stop when Jing moves. Close the Jing, slow the breath, lie down with eyes closed, perform Daoyin (guiding and pulling exercises), and then one may engage with another woman. Changing partners for each act promotes longevity. Engaging with the same woman repeatedly diminishes Yin Qi, yielding little benefit. Yang corresponds to Fire, and Yin corresponds to Water. Water controls Fire; similarly, Yin dissipates Yang. Prolonged use without cessation causes Yin to absorb Yang, leading to further loss of Yang, where gains do not compensate for losses. If one can engage with twelve women without ejaculating, one will retain beauty in old age. If one engages with ninety-three women without ejaculating, one may live ten thousand years. Scarcity of Jing leads to illness; exhaustion of Jing leads to death. This must be approached with caution. Intercourse multiple times with occasional ejaculation allows Jing to grow, preventing deficiency. Frequent intercourse with ejaculation depletes Jing, preventing regeneration, leading to exhaustion. In marriage, frequent intercourse without ejaculation preserves the essence that would otherwise be lost, enabling frequency. Ejaculating twice a month allows natural regeneration of Jing, though erection may be slower than with frequent non-ejaculatory intercourse. (Cai Nu attained the Dao early, understood nature-nurturing, lived to 170 appearing as 15. She served the King of Yin and asked Peng Zu for advice.) Peng Zu said: "Adultery shortens life not due to ghosts or gods, but because of vulgar intentions, stirring Jing to ejaculate, striving to satisfy the partner, exhausting oneself without satiety, harming rather than nourishing. This causes panic, mania, wasting-thirst, madness, or foul ulcers due to Jing loss. After ejaculation, perform Daoyin to replenish the area; otherwise, blood vessels, marrow, and brain daily decline, inviting Wind-Dampness and disease. This is because laypeople do not know the appropriateness of tonification and purgation in this context." Peng Zu said: "Men need women, and women need men. Loneliness with longing for intercourse damages lifespan and breeds a hundred diseases, attracting spirits. Losing Jing during intercourse is equivalent to a hundredfold loss. To conceive children who are long-lived, wise, and wealthy, it is best to emit Jing on the Moon's Mansion days (recorded below). Tian Zhi said: Humans contain the Five Virtues, and although forms are similar, status varies due to parents' union under the Eight Stars and Yin-Yang timing. If timing is off, the child is middle-class; if timing is right but mansion is wrong, the child is upper-class; if both are wrong, the child is ordinary. Union during proper mansion days brings wealth and honor to offspring and benefits the self, a great omen. (The Eight Stars are Shi, Shen, Jing, Gui, Liu, Zhang, Xin, Dou. When the moon resides in these stars, it is auspicious for Yin-Yang union to seek offspring.) Days 2, 3, 5, 9, and 20 of the lunar month are Wang-Xiang (Prosperous/Strong) days of vital energy. Intercourse on these days multiplies benefits fivefold, preserving blood and Qi, preventing illness. Perform gentle stimulation ('playing with Jade Spring' and 'drinking Jade Fluid') between midnight and cockcrow on these days. For union, choose Jia-Yin/Yi-Mao in Spring, Bing-Wu/Ding-Wei in Summer, Geng-Shen/Xin-You in Autumn, Ren-Zi/Gui-Hai in Winter, combined with auspicious mansion days for greater benefit. To conceive, wait one, three, or five days after menstruation ends, select a Wang-Xiang day, and emit Jing after midnight when Qi is generated. Sons born will be male, long-lived, and wise. Wang-Xiang days refer to Jia-Yi in Spring, Bing-Ding in Summer, Geng-Xin in Autumn, Ren-Gui in Winter. Health preservation hinges on cherishing Jing. Ejaculating twice a month or on the 24 Solar Terms allows living to 120. With herbal support, immortality is possible. The problem is youth ignores Dao, knowing it but not practicing; old age realizes it too late, making recovery hard. Late preservation still extends life. Practicing in youth makes immortality attainable. *Classic of Immortals* says: For mutual immortality, insert deeply without moving, visualize red Qi in the navel size of a chicken egg, move slowly, withdraw when Jing stirs. Doing this dozens of times daily increases longevity. Both partners rest, sharing intent, focusing intensely. Daoist Liu Jing said: Emit every three days in Spring, twice a month in Summer/Autumn, retain completely in Winter. Heaven stores Yang in Winter; emulating this grants longevity. One act in Winter equals a hundred in Spring. Daoist Kuai said: At sixty, one should cease all sexual activity. If one can engage without emitting, they may still interact with women. If unable, complete abstinence is best. Hundreds of medicines cannot match this for longevity. Dao Lin said: The root of life determines destiny. Even with great herbs, breathing exercises, and myriad practices, ignoring the root is futile. The root is like a tree: branches and leaves without roots cannot survive long. The root is sexual conduct. Thus, sages say: To live long, understand the source of life. Sexual conduct can generate life or kill. Like water and fire, proper use nurtures, misuse kills immediately. Intercourse while drunk or full is strictly forbidden, damaging health a hundredfold. Urinating while holding urine during intercourse causes strangury, difficulty urinating, penile pain, or lower abdominal tension. Intercourse after extreme anger causes carbuncles and sores. Taboos in the bedroom: New moons, full moons, quarter moons, eclipses, severe wind/rain, earthquakes, thunder/lightning, extreme heat/cold, seasonal transitions, and five days before/after funerals/welcoming guests are prohibited. Yin-Yang birth dates and annual/monthly taboos are especially critical (Yin-Yang mismatch harms blood/Qi, expelling righteousness and admitting evil, severely damaging healthy Qi—be warned). Freshly washed hair, post-exertion fatigue, and extreme joy/anger prohibit intercourse. Peng Zu said: One must know these regulations and avoid extreme cold/heat, wind/rain/snow, eclipses, earthquakes, and thunder (Heaven's Taboos). Drunkenness/fullness, joy/anger, sorrow/fear constitute Human Taboos. Mountains, rivers, shrines, altars, wells, and stoves constitute Earth Taboos. Avoiding these three allows selecting auspicious days: Jia-Yi in Spring, Bing-Ding in Summer, Geng-Xin in Autumn, Ren-Gui in Winter, Wu-Ji in seasonal transition months. These are Wang-Xiang days suitable for harmonious unions, promoting longevity and healthy offspring. Violating taboos causes illness and short-lived offspring. Laozi said: Returning Jing to nourish the brain prevents aging. *Classic of Zi Du* said: Emission method requires 'weak entry, strong exit' (Insert the penis gently between the teeth, then withdraw firmly; gentle insertion is 'weak entry, strong exit'. Regulate to eighty movements, completing the Yang number, which is optimal). Laozi said: 'Weak entry, strong exit' is the art of life; 'strong entry, weak exit' leads to premature death. This is the meaning.
