居常每遇岐黄家抵掌医术，辄曰∶丹溪朱先生《心法》曰，是会通《素》《难》之精，而折衷
仲景、东垣、戴人诸家，以集其成者也。每拈一方，曰∶是从先生旧方增减其间。盖人人饮食、
寒温、灾祥、生死于是，而不识先生为何他人也。丙辰，令义乌，而乃知先生义乌人也。求其书，
自《心法》诸刻以外，无闻焉。
己未，兼摄吴宁，得其刻在吴宁暑中，曰《丹溪纂要》，即吴宁卢子从其所刻石钵《荟丛》、
《钩玄》诸书，删正向，裁取之者也。急模数本以归，以为先生之真传真印尽是矣。
辛酉之秋孟，一日课诸生于司，学博陈先生曰∶闻丹溪有秘传，在其后裔而秘不传也。余曰，
果有传矣，安得秘之，当为君急索之。俄而审编于庭，而先生之裔适至，诘之，则曰∶先人手授
有《手镜》、《樵隐》二帙，藏之久矣，未敢示人也。越日，而即以其二书至。夫先生之书传三
百年矣，前之令兹土者，亦尝访而阅之矣。即余之窃禄亦已五年所矣，而任满将解之时，乃始闻
于陈先生。以是日闻于陈先生，即以是日得于其裔。三百年而未行其书，一日而行之；五年而未得
其书，一日而得之。岂先生之灵有以启余与陈先生之灵而衍其传乎？天下万世之灵有以启余与陈
先生与先生之灵而延其几坠，广其未尽乎？先生生于元之末，以先生之才之识，岂不能擘画世务
而一试于化，而仅以其医术试，而后乃显于我太宗文皇帝之朝，则后，日以医显，当日实以医隐
也，托之医而浮沉身名之间者也。先生初游许文懿公门，潜心理学，得考亭之绪，故自叙其刻曰
《格致余论》。夫医出之格致之余，则此物此知即修正诚之真脉所衍而流也。康节先生，以理衍
数，虽数亦理；先生以理精医，虽医亦理，医而出于理，而安得不信，今而传后哉。
邑历代故多豪杰君子，秦则颜乌，唐则骆中丞，宋则忠简公、文清公，元则文献公、昭代王、
龚楼三公，或以孝着，或以忠显，或以节标，或以文学传，皆表表为一代人物，至今列俎豆而光
史册，以先生之寄迹于医，阐医于道，方之诸君子，宁多让焉。董是刻者，医官丁承祖，承祖医
得先生之精，而人物亦仿佛先生云。
天启元年，冬孟之吉
平时每当遇到精通岐黄之术的医生谈论医术时，他们总是说：“丹溪朱先生的《心法》指出，这部著作融会贯通了《黄帝内经·素问》和《难经》的精髓，并折衷融合了张仲景、李东垣、刘完素（戴人）等各家学说，从而集其大成。”每拿出一个方剂，他们说：“这是从先生原有的方剂中增减变化而来的。”人们的饮食、寒暖调节、灾祸吉祥乃至生死都取决于此，却不知先生是位怎样的人物。丙辰年，我担任义乌县令，这才知道先生是义乌人。寻求他的书籍，除了《心法》等刻本外，再也听不到其他流传的书了。
己未年，我兼任吴宁县职务，得到了在吴宁暑天刊刻的书籍，名叫《丹溪纂要》，这本书就是吴宁卢子根据他所刻石的石钵《荟丛》、《钩玄》等书，删去错误、校正正误、裁减选取而成的。急忙摹印了几本带回去，认为先生真正的传承和印记都在这里了。
辛酉年秋初，有一天我在官署考核学生，学博陈先生对我说：“听说丹溪有秘传，在其后裔手中且秘密不传。”我说：“果然有传承，怎么会保密呢？应当为您急切地索取。”不久，县衙庭院里有人禀报，先生的后裔恰好到了，询问他，他说：“先祖手授有《手镜》、《樵隐》两卷，收藏很久了，不敢示人。”过了一天，这两本书就送到了。先生的书流传了三百年，之前治理此地的人，也曾访求并阅读过它。就连我窃据禄位也已经五年多了，而在任期将满准备交接之时，才从陈先生那里听说此事。因为这一天从陈先生那里听说，就在这一天从其后裔那里得到。三百年没有流通的书，一天就让它流通；五年没有得到书，一天就得到了。这难道是先生的神灵启发了我和陈先生的神灵从而延续其传承吗？天下万世的神灵启发了我和陈先生以及先生的神灵，从而延续那几乎断绝的命脉，推广那未尽的道理吗？先生生于元代末年，凭先生的才华见识，难道不能筹划世事并在教化中一试身手，而仅仅凭借医术施展，后来才在我太宗文皇帝之朝显名，那么日后日益以医术显赫，当日实际上是借医术隐居，寄托于医术而在身名之间浮沉的人啊。先生起初游学于许文懿公门下，潜心研究心性之学，继承了考亭（朱熹）的学术脉络，所以他自己叙述刻书名为《格致余论》。既然医学出自格物致知的余绪，那么这种事物这种知识就是修正诚意的真脉所衍生流淌出来的。康节先生（邵雍），以理推衍数，虽然数是理；先生以理精研医学，虽然医也是理，医学出于理，怎么能不相信，如今流传给后世呢。
我县历代故多豪杰君子，秦代有颜乌，唐代有骆中丞，宋代有忠简公、文清公，元代有文献公、昭代王、龚楼三公，有的以孝顺著称，有的以忠诚显赫，有的以气节标榜，有的以文学传世，都是杰出的一代人物，至今列入祭祀而光耀史册，凭先生寄迹于医学，阐发医学于大道，与各位君子相比，难道会有所逊色吗。主持这次刊刻的是医官丁承祖，承祖的医术得自先生的精髓，而且为人也仿佛先生一样。
天启元年，冬月初一吉日
Usually, whenever I encountered physicians proficient in the arts of Qi Bo and Huang Di discussing medical techniques, they would invariably say: "Master Zhu Danxi's *Xin Fa* (Heart Method) states that this work integrates the essence of *Su Wen* (Plain Questions) and *Nan Jing* (Classic of Difficult Issues), and synthesizes the schools of Zhang Zhongjing, Li Dongyuan, and Liu Wansu (Dai Ren) to achieve its culmination." Whenever they presented a prescription, they would say: "This is derived from Master's original prescriptions with modifications." People's diet, regulation of cold and warmth, fortune or misfortune, and even life and death depend on this, yet they do not know what kind of person the Master was. In the Bingchen year, when I served as Magistrate of Yiwu, I learned that the Master was a native of Yiwu. Seeking his books, apart from printed editions of *Xin Fa*, no other works were known.
In the Jiwu year, while concurrently administering Wuning, I obtained a book printed during the summer heat in Wuning, titled *Danxi Zuan Yao* (Compendium of Danxi). This book was compiled by Lu Zi of Wuning based on his stone-carved editions of *Huicong* (Gathering of Collections) and *Gouxuan* (Hooking the Profound), deleting errors, correcting texts, and selecting content. I hurriedly had several copies reproduced and brought them back, believing that the true transmission and authentic imprint of the Master were fully contained therein.
In the early autumn of the Xinyou year, one day while examining students at the official residence, Professor Chen said to me: "I have heard that Danxi has a secret transmission held by his descendants, which is kept secret and not passed on." I replied, "If there is indeed a transmission, how can it be kept secret? I will urgently seek it for you." Soon, an announcement came from the courtyard, and the Master's descendant happened to arrive. Upon inquiry, he said: "My ancestor hand-copied two volumes, *Shou Jing* (Hand Mirror) and *Qiao Yin* (Woodcutter Hermit), which have been stored for a long time, and I dared not show them to others." The next day, these two books arrived. The Master's works had been transmitted for three hundred years; previous magistrates of this land had also sought and read them. Even I, holding my post for over five years, only learned of this from Professor Chen just as my term was ending and I was preparing to hand over duties. Hearing about it from Professor Chen on this day, and obtaining it from his descendant on the same day: a book un circulated for three hundred years was circulated in one day; a book not obtained for five years was obtained in one day. Could it be that the spiritual presence of the Master, along with that of Professor Chen, inspired us to extend his transmission? Could the spirits of all generations under heaven, inspiring us, Professor Chen, and the Master, have extended the nearly severed lineage and broadened the未尽 principles? The Master was born in the late Yuan Dynasty. With his talent and insight, could he not have managed worldly affairs and tested himself in governance, but instead merely applied his medical skills, later becoming prominent during the reign of Emperor Taizong Wen? Thus, while he became increasingly famous for medicine in later times, at that time he actually concealed himself through medicine, floating between fame and obscurity relying on medicine. Initially, the Master studied under Lord Xu Wenyi, delving into the study of mind and nature, inheriting the academic lineage of Kaoting (Zhu Xi). Therefore, he named his own commentary on printing *Gezhi Yu Lun* (Supplementary Discussions on Investigating Things). Since medicine emerges from the aftermath of investigating things and extending knowledge, this knowledge is indeed the derivative flow of the true vein of rectifying sincerity and making thoughts genuine. Mr. Kangjie (Shao Yong) derived numbers from principles; although numbers are principles, the Master refined medicine through principles; although medicine is principles, medicine originates from principles. How can we not believe in this and transmit it to posterity now?
Our county has historically produced many heroic gentlemen: Yan Wu in the Qin Dynasty, Luo Zhongcheng in the Tang Dynasty, Zhongjian Gong and Wenqing Gong in the Song Dynasty, and Wenxian Gong, Zhaodai Wang, and the three Gongs of Lou in the Yuan Dynasty. Some were renowned for filial piety, some for loyalty, some for integrity, and some for literary achievement. All were outstanding figures of their respective eras, still listed in sacrifices and shining in history books. Compared to these gentlemen, does the Master, who devoted himself to medicine and elucidated medicine through the Dao, yield anything? The person in charge of this printing was Medical Officer Ding Chengzu. Chengzu acquired the essence of the Master's medicine, and his character resembled the Master as well.
On the auspicious first day of the first month of winter, in the first year of Tianqi.
