天一生水，命曰真阴。真阴亏，则不能制火，以致心火炎上而克肺金，于是发热、咳嗽
、吐痰诸症生焉。盖发热者，阳烁阴也；咳嗽者，火刑金也；吐痰者，肾水虚泛而为痰，如
锅中之水，热甚则腾沸也。当此时势，岂徒区区草木之功所能济哉！必须取华池之水，频频
吞咽，以静治于无形。然后以汤丸佐之，庶几水升火降，而成天地交泰之象耳。主方在吞津
液。华池之水，人身之金液也，敷布五脏，洒陈六腑，然后注之于肾而为精。肾中阴亏，则
真水上泛而为痰，将并华池之水，一拥俱出。痰愈多而肌愈瘦，病诚可畏。今立一法，二六
时中，常以舌抵上 ，令华池之水，充满口中，乃正体舒气，以意目力送至丹田，口复一口
数十乃止。此所谓以真水补真阴，同气相求，必然之理也。每见今之治虚者，专主六味地
黄等药，以为滋阴壮水之法，未为不善，而独不于本原之水，取其点滴以自相灌溉，是舍真
求假，不得为保生十全之计，此予所以谆谆而为是言也。卫生君子，尚明听之哉！
昔者纯阳吕祖师，出卖人参果，一纹一枚，专治五劳七伤，诸虚百损。并能御外邪，消
饮食，轻身不老，却病延年。真神丹妙药也。市人闻之，环聚争买者千余人。祖师大喝曰∶
此果人人皆有，但汝等不肯服食耳。众方醒悟。今之患虚者众矣，或归怨贫乏而无力服参，
或归怨医家不早为用参，或归怨医家不应早用参，或归怨用参之太多，或归怨用参之太少，
或归怨用参而不用桂、附以为佐，或归怨用参而不用 、术以为援，或归怨用参而不用二地
、二冬以为制。议论风生，全不反躬自省，以致屡效屡复，难收全功。不佞身肩是任，
宁敢造次，博稽古训，百法追寻，每见历代良医，治法不过若此。于是睁开目力，取来参果
一车，普送虚人服食。凡病危而复安者，不论有参无参，皆其肯服参果者也。凡病愈而复发
者，不论有参无参，皆其不服参果者也。世人请自思维，定知此中消息。惟愿患者各怀其宝
必然服药有功，住世永年，无负我祖师垂救之至意，是恳是祷。
以上数篇，发明医中之误，细详调摄之方，盖弭患于未萌，治未病之意也。后此皆言治
天一之水，被称为真阴。真阴亏损，就不能制约火气，导致心火炎上而克制肺金，于是发热、咳嗽、吐痰等症状就产生了。大概发热，是阳热灼烧阴液；咳嗽，是火气刑克肺金；吐痰，是肾水虚弱泛滥而成痰，就像锅里的水，热气太盛就会沸腾翻滚一样。在这个时候，难道仅仅是普通的草木药物所能救治的吗！必须取用口中津液，频繁吞咽，以静定的方式在无形之中调理。然后用汤剂或丸药辅助，差不多就能实现水升火降，形成天地交泰的景象了。主方在于吞咽津液。口中的津液，是人身的“金液”，它敷布于五脏，洒陈于六腑，然后注入肾脏化为精。如果肾中阴液亏损，真水上泛成为痰，连同口中的津液也会一并涌出。痰越多身体越消瘦，这病确实令人畏惧。现在我确立一种方法，在一天十二个时辰中，经常用舌抵住上颚，让口中的津液充满口腔，然后端正身体，舒展气息，用意念和目光将其送至丹田，口复一口（即吞咽）数十次后停止。这就是所说的用真水来补真阴，同气相求，这是必然的道理。我常看到现在治疗虚证的人，专门主张使用六味地黄等药物，认为这是滋阴壮水的方法，这并非不好，只是唯独不在本源之水中，取点滴来自我灌溉，这是舍弃真源而追求假借，不能算是保全生命、十全十美的计策，这就是我谆谆告诫说这些话的原因。注重养生的人士，请明白听取吧！
从前纯阳吕祖师，出卖人参果，一枚一钱，专门治疗五劳七伤，各种虚损百病。并且能抵御外邪，消化饮食，使身体轻健不老，祛除疾病延长寿命。真是神丹妙药啊。市场上的人听说后，聚集争买的一千多人。祖师大声喝道：“这果子人人都有，只是你们不肯服用罢了。”众人这才醒悟。现在患虚证的人很多，有的抱怨贫穷无力服用参类药材，有的抱怨医生没有早点使用参类药材，有的抱怨医生不应该早点使用参类药材，有的抱怨使用参类药材太多，有的抱怨使用参类药材太少，有的抱怨使用参类药材时不用桂枝、附子作为佐使，有的抱怨使用参类药材时不用白术、茯苓作为援助，有的抱怨使用参类药材时不用生地、熟地、天冬、麦冬作为制约。议论纷纷，完全不反躬自省，导致病情屡效屡发，难以取得完全疗效。我身负此任，怎敢草率行事？广泛考察古训，追寻百种方法，每见历代良医，治疗方法不过如此。于是睁开眼力，取来装满一车的人参果，普遍赠送给虚损之人服用。凡是病情危重而后恢复安好的，不论是否有参类药材，都是那些肯服用人参果的人。凡是病情痊愈而后复发的，不论是否有参类药材，都是那些不服用人参果的人。世人请自行思考，必定知道其中的奥秘。只希望患者各自怀藏其宝，必然服药有效，居住世间永远延年，不辜负我祖师垂救的至深心意，这是我的恳切祈祷。
以上几篇，阐明了医学中的误区，详细详述了调养摄生的方法，大概是防患于未萌生之时，体现了治未病的意旨。此后皆言治疗……
Heaven One generates Water, which is named True Yin (Zhen Yin). When True Yin is deficient, it cannot control Fire, leading to Heart Fire flaring upward and overcoming Lung Metal. Consequently, symptoms such as fever, coughing, and expectoration arise. Fever is essentially Yang scorching Yin; coughing is Fire punishing Metal; expectoration occurs because Kidney Water is deficient and overflows like phlegm, similar to water in a pot boiling vigorously when the heat is intense. At this juncture, can mere ordinary herbs achieve the cure? One must take the water from the "Huachi" (Sacred Pool, referring to saliva), swallow it frequently, and regulate the formless with stillness. Only then, assisted by decoctions or pills, can one hope for Water ascending and Fire descending, thereby achieving the image of Heaven and Earth interacting harmoniously (Tian Di Jiao Tai). The primary prescription lies in swallowing saliva. The water of Huachi is the "Golden Fluid" of the human body; it spreads through the Five Zang organs, irrigates the Six Fu organs, and then enters the Kidneys to become Essence. If Yin within the Kidneys is deficient, True Water overflows to become phlegm, and even the water of Huachi will gush out together. The more phlegm there is, the thinner the body becomes; this illness is indeed fearsome. I now establish a method: throughout the twenty-four hours (twelve double-hours), frequently press the tongue against the upper palate so that the water of Huachi fills the mouth. Then, correct the posture, relax the breath, and use intention and visual focus to send it to the Dantian. Swallow dozens of times and then stop. This is what is meant by using True Water to supplement True Yin; seeking resonance with the same Qi is an inevitable principle. I often observe that those who treat deficiency nowadays exclusively rely on formulas like Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) for nourishing Yin and strengthening Water. While not incorrect, they fail to take drops from the source water for self-irrigation. This is abandoning the true for the false and cannot be considered a perfect plan for preserving life. This is why I earnestly speak these words. Gentlemen who value health, please listen carefully!
In ancient times, Patriarch Lü Chunyang (Lü Dongbin), known as the Pure Yang Patriarch, sold Ginseng Fruit at the price of one coin per piece. It specifically treated the Five Exhaustions and Seven Injuries, and all kinds of deficiencies and damages. It could also ward off external pathogens, aid digestion, lighten the body, prevent aging, eliminate disease, and prolong life. Truly a miraculous elixir! Upon hearing this, thousands gathered in the market to compete for purchase. The Patriarch shouted loudly: "This fruit is possessed by everyone, but you refuse to consume it." Only then did the crowd awaken. Nowadays, many suffer from deficiency. Some blame poverty for being unable to afford Ginseng; some blame doctors for not using Ginseng early enough; some blame doctors for using Ginseng too early; some complain about using too much Ginseng; some complain about using too little Ginseng; some complain that when using Ginseng, Cinnamon Twig (Guizhi) and Aconite Root (Fuzi) are not used as assistants; some complain that White Atractylodes Rhizome (Baizhu) and Poria Sclerotium (Fuling) are not used as reinforcements; some complain that Prepared Rehmannia Root (Shu Dihuang), Raw Rehmannia Root (Sheng Dihuang), Asparagus Tuber (Tian Dong), and Ophiopogon Tuber (Mai Dong) are not used to moderate its effects. Discussions abound, yet no one reflects upon themselves, resulting in repeated efficacy followed by recurrence, making complete recovery difficult. Bearing this responsibility, how dare I act rashly? I have extensively consulted ancient teachings and traced hundreds of methods. Observing the treatments of excellent physicians through the dynasties, their methods were no different. Thus, opening my eyes, I took a cartload of Ginseng Fruit and distributed it universally to those with deficiency. All those whose critical conditions recovered were those willing to consume the Ginseng Fruit, regardless of whether other herbs were present. All those whose cured conditions relapsed were those unwilling to consume the Ginseng Fruit, regardless of other herbs. People, please ponder this yourselves, and you will surely understand the secret within. I only wish that patients would cherish their own treasures, ensure the efficacy of medication, live long lives, and not fail the profound intent of my Patriarch's salvation. This is my sincere prayer.
