先春养阳法 每日闭目冥心而坐，心注定肾中，咽津七口，送下丹田。起立，双手自抱两胁，微摇者三，如打
拱状，起立俟气定再坐，如前法，咽津七口，送下丹田。永无风症之侵，一月行六次可也，多多更妙。
先夏养阴法 每日闭目冥心而坐，心注定于心，咽津十四口，送下心中，永无暑气之侵。
先秋养阴法 每日闭目冥心而坐，心注肺中，咽津送下丹田者十二口，以双手攀足心者三次，俟气定，再如前
咽津，送下丹田者七口而后止，永无燥热之病。
先冬养阳法 每日五更坐起，心中注定两肾，口中候有津水，送下丹田者三口，不必漱津，以手擦足心，火热
而后已。再送津三口至丹田，再睡。永无伤寒之症，而长生之法，亦在其中矣。长夏不必更有方法。（俱《石室秘 》）
一慎风寒 沐浴临风，则病脑风痛风。饮酒向风，则病酒风、漏风。劳汗暑汗当风，则病中风、暑风。夜露乘
风，则病寒热。卧起受风，则病痹厥。衣凉冒冷，则寒外侵。饮冷食寒，则寒内伤。（人惟知有外伤寒，而不知有内伤寒，
讹作阴症，非也。凡冷物不宜多食，不独房劳为然也。周扬俊曰∶房劳未尝不病阳症，头痛发热是也，但不可轻用凉药
耳。若以曾犯房劳，便用温药，杀人多矣。愚按∶诸书从未有发明，及此者，世医皆罕知之，周子此论，可谓有功于世
矣。）早起露首跣足，则病身热头痛。纳凉阴室，则病身热恶寒。多食凉水瓜果，则病泄痢腹痛。夏走炎途，贪凉食冷，
则病疟痢。
一戒受湿 坐卧湿地，则病痹厥疠风。冲风冒雨，则病身痛。长着汗衣，则病麻木发黄。勉强涉水，则病香港脚
挛痹。饥饿澡浴，则病骨节烦痛。汗出见湿，则病痤痱。（痤，疖也。音坐，平声。）
一节饮食 经曰∶饮食自倍，肠胃乃伤。膏粱之变，能生大疔。（即外痈亦皆由此。）亦膏粱之疾，消瘅痿厥。
饱食太甚，筋脉横解，肠 为痔。饮食失节，损伤肠胃。始病热中，末传寒中。怒后勿食，食后勿怒。醉后勿饮冷（引
入肾经则有腰脚肿痛之病，）饱食勿便卧。饮酒过度，则脏腑受伤，肺因之而痰嗽，脾因之而倦怠，胃因之而呕吐，心因
之而昏狂，肝因之而善怒，胆因之而忘惧，肾因之而烁精，膀胱因之而溺赤，二肠因之而泄泻，甚则劳嗽失血，消渴黄
疸，痔漏疮毒，为害无穷。咸味能泻肾水，损真阴。辛辣大热之味，皆损元气，不宜多食。
一禁淫欲 男子二八而天癸至，女子二七而天癸至，交合太早，斫丧天元，乃夭之由。男子八八而天癸绝，女
人七七而天癸绝，精血不生，入房不禁，是自促其寿矣。人身之血，百骸贯通，及欲事作，撮一身之血至于命门，化精
以泄。（人工受胎，皆禀此命火以有生。故庄子曰，火，传也，不知其尽也。）夫精者，神倚之，如鱼得水。（神必根据物方
有附丽。故关尹子曰∶精无人也，神无我也。（《楞严经》）曰∶火性无我，寄与诸缘。）气根据之，如雾覆渊。不知节啬，
则
百脉枯槁。交接无度，必损肾元，外虽不泄，精已离宫，定有真精数点，随阳之痿而溢出，如火之有烟焰，岂能复返于
薪哉。
一忌过伤 久视伤血，久卧伤气，久坐伤肉，久立伤骨，久行伤筋。暴喜伤阳，暴怒伤肝，穷思伤脾，极忧伤
心，过悲伤肺，多恐伤肾，善惊伤胆。多食伤胃，醉饱入房伤精，竭力劳作伤中。春伤于风，夏为餐泄。夏伤于暑，秋
为痰疟。秋伤于湿，冬必咳嗽。冬伤于寒，春必病温，夜寝勿言语，大伤元气。（《修养杂 》）
[Pre-season Caution / Essentials of Health Preservation]
**Nourishing Yang in Early Spring**: Each day, sit with eyes closed and mind quieted, focusing the spirit (Shen) into the Kidneys. Swallow saliva seven times, guiding it down to the Lower Dantian. Stand up, embrace both hypochondria with hands, and sway slightly three times, resembling the gesture of bowing with hands clasped. After standing, wait for the breath to settle before sitting again. Follow the previous method: swallow saliva seven times and guide it to the Lower Dantian. Practicing this perpetually prevents invasion by Wind pathogens. Six sessions per month are sufficient; more is better.
**Nourishing Yin in Early Summer**: Each day, sit with eyes closed and mind quieted, focusing the spirit into the Heart. Swallow saliva fourteen times, guiding it into the Heart. This permanently prevents invasion by Summerheat pathogens.
**Nourishing Yin in Early Autumn**: Each day, sit with eyes closed and mind quieted, focusing the spirit into the Lungs. Swallow saliva and guide it to the Lower Dantian twelve times. Then, grasp the soles of the feet with both hands three times. Wait for the breath to settle, then follow the previous method: swallow saliva and guide it to the Lower Dantian seven times, then stop. This permanently prevents diseases of Dryness and Heat.
**Nourishing Yang in Early Winter**: Rise at the Wugeng hour (approx. 3–5 AM), focus the mind on both Kidneys. When saliva accumulates in the mouth, send three mouthfuls to the Lower Dantian. Do not rinse the mouth. Rub the soles of the feet with hands until heat is generated. Then send another three mouthfuls of saliva to the Lower Dantian and return to sleep. This permanently prevents Cold Damage syndromes, and the method of longevity is included within it. No additional methods are needed for the Long Summer season. (All from *Shishi Milu*)
**1. Be Cautious of Wind and Cold**: Bathing while exposed to wind causes Brain Wind (nao feng) and Gouty Wind (tong feng). Drinking alcohol while facing wind causes Wine Wind (jiu feng) and Leakage Wind (lou feng). Exposing sweat from labor or summerheat to wind causes Stroke-Wind (zhong feng) and Summerheat-Wind (shu feng). Exposing oneself to night dew and wind causes alternating chills and fever. Catching wind upon waking or sleeping causes Bi syndrome (bi jue) and Jue syndrome. Wearing cool clothes in the cold allows external Cold to invade. Drinking cold water and eating cold food injures the interior with Cold. (People only know of external Cold injury but ignore internal Cold injury, mistakenly diagnosing it as Yin syndrome, which is incorrect. Cold foods should not be consumed excessively; this applies not only to sexual exhaustion. Zhou Yangjun stated: Sexual exhaustion does not necessarily cause Yang syndromes, such as headache and fever, but one must not lightly use cooling herbs. If warm herbs are used simply because of prior sexual excess, many will die. I believe no medical texts have clarified this point previously, and most physicians are unaware of it. Zhou’s discussion is indeed beneficial to the world.) Exposing the head and bare feet early in the morning causes body heat and headache. Seeking coolness in dark rooms causes body heat and aversion to cold. Consuming excessive cold water and fruits causes diarrhea, dysentery, and abdominal pain. Walking in hot weather during summer and greedily consuming cold food/drinks causes Malaria (nüe) and dysentery.
**2. Avoid Dampness**: Sitting or lying on damp ground causes Bi syndrome, Jue syndrome, and Leprosy-Wind (li feng). Facing wind and braving rain causes body pain. Wearing wet clothes causes numbness and jaundice. Forcing oneself to wade through water causes Hong Kong Foot (foot qi/jiaojixi), spasms, and Bi obstruction. Bathing while hungry causes painful joints. Experiencing dampness after sweating causes acne/furuncles (cuo) and prickly heat (fei). (Cuo refers to furuncles. Pronounced zuò, level tone.)
**3. Moderate Diet**: The Classics state: "If diet doubles, the intestines and stomach are injured." Changes caused by rich and greasy foods can generate large Ding sores (even external abscesses arise from this). These are also diseases of rich diets, leading to Xiao Dao (wasting-thirst), Wei syndrome (flaccidity), and Jue syndrome. Overeating causes tendons and vessels to relax and intestines to become hemorrhoids. Irregular diet damages the intestines and stomach. Initially, it manifests as Heat in the Middle (Re Zhong), later transmitting to Cold in the Middle (Han Zhong). Do not eat after anger; do not get angry after eating. Do not drink cold water after intoxication (this introduces pathogenic factors into the Kidney meridian, causing swelling and pain in the waist and legs); do not lie down immediately after full meals. Excessive drinking damages the Zang-Fu organs: the Lungs develop phlegm and cough due to it; the Spleen becomes fatigued; the Stomach vomits; the Heart becomes confused and manic; the Liver becomes irritable; the Gallbladder loses courage; the Kidneys consume essence; the Bladder produces red urine; the Large and Small Intestines cause diarrhea. Severe cases lead to consumptive cough with blood loss, wasting-thirst, jaundice, hemorrhoids, fistulas, and sores, causing endless harm. Salty flavors drain Kidney Water and damage True Yin. Pungent and extremely hot flavors all damage Yuan Qi and should not be eaten in excess.
**4. Prohibit Sexual Licentiousness**: Men reach Tian Gui (menstrual/sexual maturity substance) at age sixteen; women at age fourteen. Premature intercourse chops away and depletes Heavenly Origin, leading to premature death. Men cease Tian Gui at age sixty-four; women at age forty-nine. When Jing and Blood are no longer produced, engaging in sex without restraint shortens one's lifespan. Blood in the human body permeates all bones and limbs. When desire arises, blood from the whole body is drawn to the Mingmen (Gate of Life) to transform into Essence and ejaculate. (Human conception relies on this Mingfire for life. Thus, Zhuangzi said: Fire is transmitted, knowing no end.) Essence is what the Spirit (Shen) leans upon, like a fish relying on water. (Spirit must attach to an object to have a basis. Thus, Guanyinzi said: Essence has no self; Spirit has no ego. The *Lankavatara Sutra* states: Fire nature has no self, depending on various conditions.) Qi relies on Essence, like mist covering an abyss. Without moderation and conservation, the hundred vessels will wither. Unrestrained intercourse inevitably damages Kidney Yuan. Even if ejaculation does not occur externally, the Essence has left its palace. A few drops of true Essence will overflow along with the flaccidity of the Yang, just as fire produces smoke and flames; how can these return to the firewood?
**5. Avoid Overstrain**: Prolonged vision injures Blood; prolonged lying injures Qi; prolonged sitting injels flesh; prolonged standing injures bones; prolonged walking injures sinews. Sudden joy injures Yang; sudden anger injures the Liver; excessive thinking injures the Spleen; extreme sorrow injures the Heart; excessive grief injures the Lungs; frequent fear injures the Kidneys; frequent startling injures the Gallbladder. Overeating injures the Stomach; sex after drunkenness/fullness injures Essence; exhausting labor injures the Center (Middle Jiao). Injury by Wind in Spring leads to postprandial diarrhea in Summer. Injury by Summerheat in Summer leads to Phlegm-Malaria in Autumn. Injury by Dampness in Autumn leads to cough in Winter. Injury by Cold in Winter leads to Warm diseases in Spring. Do not speak while sleeping at night, as this severely damages Yuan Qi. (From *Xiuyou Za Ji*)
