闻之左氏云∶“去疾莫如尽。”余于病目之余，而知
斯言也。不仅为病者之针砭，而实治病者之龟鉴
也。尝见世之庸俗疗目疾者，不睹真人《秘诀》真传，
辄以人知病者之急欲痊也，投之劫剂，以取效于旦夕，
后病复作，治如前法，常自诩于人曰∶“某也屡病，
除余莫能疗也。”病者亦心佩之，曰∶“先生屡活我。”不
穷其本，而图速成之功，往往致沉痼焉。惟益都马
云从先生则异。是先生本儒生，中年得孙真人神方，
遂以治目鸣东海。五十年间，仰金 而睹日月
者，指不胜屈。复以秘枕诸方，剞劂已久，未印成集。
余同姐丈王子懋功，乐出囊金，广印以公海内，俾审
病印方，即获奇效焉。余简阅至再，大抵穷原晰微，
无欲速以媚世，盖深得乎“去疾务尽”之一言，而龙
宫密受，适足以神其调剂也。余病目缠绵多年，时发
时愈，亦受愚于盲医。今先生赐神楼一七，数日辄开
爽。余欣谢之，先生曰∶“未也，此庸人索谢时耳。欲
芟其根，当以月计。”果调息至数月而愈。先生
曰∶“五内气清，无复余患矣。”自此瞻青仰白，皆
先生赐也。余固佩先生之德，而并以己之受治，非祈
速效者，为同人告，使知儒者之术，其利溥哉！
癸未孟春关中张玮敬跋
我听说左丘明说过：“去除疾病，没有比彻底根除更好的了。”我在治疗眼病的经历中，深刻体会到了这句话的含义。这不仅是给患者听的忠告，更是给医生看的镜子。
我曾经见过世间那些庸俗的眼科医生，他们看不到华佗（真人）《秘诀》中的真传，就利用病人急于痊愈的心理，使用猛烈的攻伐药物，以求在早晚之间见效。后来病情复发，再用同样的方法治疗，常常自夸对人说：“某某多次患病，除了我没人能治好。”病人也心里感激地说：“先生多次救活了我。”这些医生不探究疾病的根本，只图快速见效，往往导致疾病变成难以治愈的沉疴。
只有益都的马云从先生则不同。这位先生本是读书人，中年时得到了孙思邈（孙真人）的神方，于是开始在东海地区用此法治疗眼病。五十年来，仰视金银、目睹日月的人，数不胜数。他又将秘藏的枕中方等药方，刻印已久，但尚未集结成书出版。
我的姐夫王子懋功，乐意出资，广泛印刷以公开于世内，使人们能够根据病情对应药方，立即获得奇效。我反复审阅，发现大抵都是探究本源、剖析细微，没有为了迎合世俗而追求速效，这确实深得“去除疾病务必彻底”这一句话的精髓，而且龙宫密授（指代秘方来源神圣），恰好足以彰显其配伍调剂的神奇。
我患眼病缠绵多年，时好时坏，也曾被庸医愚弄。如今先生赐给我“神楼”一剂（注：此处“神楼”可能为特定方剂名或笔误，依原文保留），几天后眼睛就感到清爽开阔。我欣喜地感谢他，先生说：“还没完，这是庸俗之人索取谢礼时的说辞罢了。想要剪除病根，应当以月为单位来计算疗程。”果然调理呼吸（指服药调养）几个月后才痊愈。先生说：“五脏之气清朗，不再有残余病患了。”从此以后，我看青看白，都是先生赐予的。我固然感激先生的恩德，并且把自己的受治经历——不是祈求速效而是求根治——告诉同僚，让他们知道儒者医术的利益是多么广博啊！
癸未年孟春（正月），关中张玮恭敬地写下跋文。
I have heard Zuo Qiuming say: "To eliminate disease, nothing is better than thorough eradication." In my experience of treating eye diseases, I have come to understand the truth of this statement. This serves not only as a warning for patients but also as a mirror for physicians.
I have often seen vulgar practitioners of eye diseases in the world who, lacking access to the true transmission found in Hua Tuo's (Zhenren) *Secret Manual*, exploit the patient's urgency for recovery by administering harsh purgative or attacking agents to achieve immediate results within a day or night. When the disease recurs, they employ the same methods again, often boasting to others, saying, "So-and-so has suffered repeatedly; only I can cure him." The patients, too, harbor gratitude in their hearts, saying, "The Master has saved me many times." By failing to investigate the root cause and seeking only rapid success, these practitioners often lead to chronic, intractable conditions.
However, Mr. Ma Yuncong from Yidu is different. Originally a scholar, he obtained the divine prescriptions of Sun Simiao (Sun Zhenren) in his middle age and subsequently treated eye diseases in the Donghai region. Over fifty years, the number of people who could look up at gold and see the sun and moon has been countless. He had long since carved the woodblocks for his secret pillow formulas (*Zhenzhong Fang*) but had not yet published them as a collected work.
My sister's husband, Wang Mugong, was willing to contribute funds to widely print these works for public dissemination, enabling people to match their conditions with the formulas and achieve miraculous effects immediately. After reviewing the text multiple times, I found that it generally explores the origin and clarifies the subtle details, without seeking speed merely to flatter the world. It truly embodies the principle of "thorough eradication of disease," and its mysterious transmission (metaphorically referred to as received from the Dragon Palace) perfectly highlights the efficacy of its formulation and adjustment.
I suffered from persistent eye disease for many years, fluctuating between remission and exacerbation, and was also deceived by quack doctors. Recently, Mr. gifted me one dose of *Shenlou* [Divine Pavilion Formula], and within a few days, my vision became clear and refreshing. I thanked him joyfully, but he said, "It is not finished. That is what ordinary people say when soliciting thanks. To eradicate the root, one must measure progress in months." Indeed, after regulating breathing and taking medicine for several months, I recovered completely. Mr. said, "The Qi of the five zang organs is now clear, and no residual ailments remain." From then on, seeing green and white were gifts bestowed by Mr. I am deeply grateful for his virtue and wish to share my own treatment experience—that one should not seek quick fixes but rather thorough cure—with my colleagues, so that they may know how beneficial the art of the Confucian physician can be!
