唐代时有一卷来自西域的治疗疾病的方法。这是西域仙人传授的，见于《艺文志》。我在《小蓬莱谣》中写道：“炼就金丹一粟黄，不堪大众共分尝。待游西域仙人到，备说人间治疾方。”指的就是这个。道家所说的龙虎铅汞（道教炼丹术中的术语），只是空谈。桐柏真人用大还丹（道教认为能使人长生不死的丹药），命令张老沿街叫卖。究竟谁白日升天而去了呢？不如王侯的单方（民间流传的有效验方），救人疾苦，不失为菩萨心肠。心禅和尚隐居在佛教寺院中，却精通医学。他论述医学的各个条目，无不细致入微。不是精研《黄帝内经》和《难经》（中医经典著作）的书，不能说出只言片语。选取这些附在医案之后，更能看出其运用的灵活机智，不拘泥于死板的方法。和尚在此道上行医三次折断手臂（比喻阅历丰富，经验丰富）了。庚寅年初夏，我住在右台仙馆。和尚来拜访，并拿出这一编书请求作序。我虽然不懂医学，但一向知道和尚精通医学，就在书的简端写了几句话，让人们知道扁鹊、仓公（古代名医）中本来就有隐居在世俗之外的人，不要只在市井中那些悬挂葫芦行医的人那里寻找。曲园居士俞樾。
医学之道虽然微小，但救济世人功劳与良相相同。古人难道欺骗我吗？僧人心禅来到杭州已有多年，而我们杭州的奇难病症，依靠他得以保全生命的不少。医案是摘取其中特别优秀的，仅占十分之一二罢了。我颇为沉迷医书，而心禅上窥《黄帝内经》和《难经》的秘密典籍，下至汉魏六朝唐宋元明以及清朝初年各位大家的著作，无不穷尽精力，精心研究。选择精粹，手抄成册。每次与我谈论，从头到尾，如数家珍，而且口若悬河，总觉得灵思纷飞，头头是道。确实值得称赞。这次有去上海之行，袖出医案，向我询问序言。我认为心禅，根基之学既深，又能在临症之际，精神与古人相会，不轻易下笔，这真是食古而化，不拘泥于古法的人，不更值得称赞吗？从此所得益处更深，造诣更进一步，日新月异，积累成巨著。日后回去携带南海，焚香献给佛。迦叶（佛陀弟子）应当必定在旁边拈花微笑说：大士（指观音菩萨或高僧）救济世人的慈悲心，就是这样就是这样。

In the Tang Dynasty, there was a volume of prescriptions for treating diseases from the Western Regions. This was transmitted by immortals of the Western Regions and is recorded in the *Yiwen Zhi* (Bibliographic Treatise). In my poem "Song of Xiaopenglai," I wrote: "Refined into a golden elixir, a grain of yellow, / Not suitable for the masses to share and taste. / Wait for the immortal of the Western Regions to arrive, / To recount thoroughly the prescriptions for curing diseases in the human world." This refers to this very work. The Daoist discussions on Longhu (Dragon and Tiger), Qian (Lead), and Gong (Mercury) are merely empty talk. Tongbai Zhenren (True Person of Tongbai), using the Great Return Elixir (a Daoist elixir believed to grant immortality), ordered Zhang Lao to sell it door-to-door. Ultimately, who ascended to heaven in broad daylight? It is better than the single prescriptions of nobles, which save people from suffering and retain the compassionate heart of a Bodhisattva. Master Xinchan lived in seclusion within Buddhism but was proficient in medicine. His discussions on various medical topics were meticulous and profound. Only one who has meticulously studied the *Huangdi Neijing* (Yellow Emperor's Inner Canon) and *Nanjing* (Classic of Difficult Issues) could utter even a single word. Including these alongside the medical cases further reveals his flexible application of principles, not bound by rigid methods. Master Xinchan had gained extensive experience in this field (literally: broke his arm three times, implying deep expertise through repeated practice). In early summer of the Gengyin year, I resided at the Youtai Xianguan. Master Xinchan visited me and presented this compilation, requesting a preface. Although I do not understand medicine, I have long known that Master Xinchan is proficient in it. Thus, I wrote a few words on the frontispiece to let people know that Bian Que and Cang Gong (ancient famous physicians) included those who secluded themselves outside the secular world, and one should not seek them only among those hanging gourd signs in the marketplace. Qu Yuan Jushi (Scholar Qu Yuan), Yu Yue.
The Way of Medicine may be small, but its benefit to the world is equal to that of a good chancellor. Did the ancients deceive us? Monk Xinchan came to Hangzhou many years ago, and many rare and difficult cases in our Hangzhou relied on him to survive. The medical cases selected here are only the most outstanding ones, comprising merely one or two tenths of the whole. I am quite devoted to medical books, while Xinchan has explored the secret manuals of the *Neijing* and *Nanjing*, and down to the major masters of the Han, Wei, Six Dynasties, Tang, Song, Yuan, Ming dynasties, and the early Qing period, exhausting his spirit and energy. He selected the essence and copied them by hand into volumes. Whenever he discussed with me, he traced the origins and branches, as if counting family treasures, and spoke fluently, with inspired thoughts flowing freely, every point logical and sound. This is truly commendable. Now, having a trip to Shanghai, he took out the medical cases from his sleeve and asked me for a preface. I believe that Xinchan, with his deep foundational learning, can also spiritually connect with the ancients when treating patients, not writing lightly. This is truly assimilating the past and transforming it, not strictly bound by ancient methods, which is even more commendable. From then on, his gains became deeper, his attainment advanced, day by day growing new and prosperous, accumulating into a massive compilation. In the future, upon returning, he will carry it to Nanhai, burn incense, and offer it to the Buddha. Kasyapa (one of the Buddha's disciples) would surely smile beside him, holding a flower, saying: The Bodhisattva's compassionate heart to save the world is indeed so, indeed so.
