从前，陈师文、裴宗元曾经编定《大观》二百九十七首方剂，后来得到朱丹溪对其学说进行订正。他们的一切判断都依据《黄帝内经》《素问》和《难经》，这便成为了医学的宗旨。由此可知，疾病没有医术就无法医治，医术如果没有通达至高大道的人来传授，就不会被重视。为什么呢？因为“道”能够统摄并指导“术”，所以人们信赖医术是因为其中蕴含了“道”。
我（谦称）曾在郡中侍奉王太守大人，私下观察到他在应对纷繁复杂的病情时，神态从容充裕，精神精明爽朗，面色光泽，元气坚固，言谈吐露多根源于《内经》《素问》，娓娓道来地剖析大道的玄妙旨意。有一天在聚和堂聚会时，他向我展示《仁术便览》这本书，说：“这是同乡张氏编纂的，试用后一一有效，因此刻印流传。”唉呀，这大概是真正能看重张氏著作的人吧！
况且我听说医家将气血壅滞、闭塞不通导致的痿证、痹证称为“不仁”，天下阅读此书掌握医术的人，如果能融会贯通那些被视为“不仁”的病证而施以仁爱救治，那么医术就会因“道”而确立，“道”就会因医术而推广，这将弥补造化的不足，使大众如沐春风。何必像朱丹溪那样，仅仅以医生身份闻名于世呢？所以说，道的真谛用来修身养性，道的余绪用来治理天下国家，王公大人就具备了这些品质。
万历乙酉年（1645年）冬十月初一，杞人周九皋书写。
In the past, Chen Shiwen and Pei Zongyuan once compiled two hundred and ninety-seven prescriptions from the *Daguan* era, which were later revised by Zhu Danxi. Their judgments were entirely based on the *Huangdi Neijing* (Yellow Emperor's Inner Canon), the *Suwen* (Basic Questions), and the *Nanjing* (Classic of Difficult Issues), thereby establishing the fundamental principles of medicine. This indicates that diseases cannot be treated without medical art, and medical art, if not transmitted by one who has attained the Supreme Way (Dao), will not be valued. Why? Because the Way guides and empowers the Art; thus, people trust the Art because it is rooted in the Way.
I humbly served Governor Wang in the commandery and privately observed his ability to respond adeptly to complex and numerous clinical situations. His demeanor was calm and abundant, his spirit clear and bright, his complexion lustrous, and his vital Qi solid. In conversation, he often drew upon the *Neijing* and *Suwen*, eloquently dissecting the profound mysteries of the Dao. One day, during a gathering at the Juzhe Hall, he showed me the book *Renshu Bianlan* (Convenient Guide to Benevolent Medical Arts), saying: "This was compiled by Mr. Zhang, my fellow townsman. Having tested it, every case proved effective; therefore, it is being printed for dissemination." Alas, this person truly values Mr. Zhang's work!
Furthermore, I have heard that physicians refer to conditions characterized by obstruction, blockage, flaccidity, and numbness as "Bu Ren" (Non-Benevolence/Insensitivity). Those in the world who study this medical art should integrate their understanding of these "non-benevolent" conditions with benevolence to treat them. In this way, the Art will be established through the Way, and the Way will be expanded through the Art. This will help remedy the limitations of nature and bring the warmth of spring to the general public. Why should one merely seek fame as a physician like Zhu Danxi? Therefore, it is said: The essence of the Dao is used to cultivate oneself, while its remnants are used to govern the world and the state. Governor Wang possesses these qualities.
