I have had the privilege of knowing Mr. Gan Ren for many years. Mr. Gan once said, "The Way cannot be practiced without technique." In the past, I heard this and doubted it, secretly thinking that sometimes itinerant practitioners keep their skills secret to demand high fees from people. Although medicine is a minor art, it is entrusted with the lives of patients, dealing with emergencies and life-and-death situations. How can one rely on mere technique? Mr. Gan replied, "There is a reason for this. In ancient times, Bian He found a fine piece of uncut jade and presented it to the King of Chu at Jing Terrace. The king thought it was just an ordinary stone and refused it three times, eventually cutting off Bian He's feet. The King of Qi loved the yu, a type of flute, and Yongmenzi stood at the king's gate with his qin for three years but was never granted an audience. Yongmenzi's qin was indeed excellent, but what could he do if the king did not appreciate it? When the relationship is shallow and the words are deep, gaining trust is difficult, especially in moments of life and death. If one seeks quick results and administers strong medicine, the patient will fear it; if one is unfamiliar and casually shares their innermost thoughts, the patient will doubt it. When doubt and fear intertwine, even the best medicine will ultimately be discarded. Alas! This is like the jade at Jing Terrace and the qin at the king's gate, the very things that caused Bian He and Yongmenzi such heartache. I have heard that the ancient skilled physicians were called 'He' (harmony) and 'Huan' (gentleness). Harmony means no harsh or drastic medicine, and gentleness means no overly urgent effects. All of this is to avoid arousing suspicion and fear in people and to strengthen their confidence. This is why 'He' and 'Huan' are renowned, and this is their technique. Mr. Gan's words are thus, and from them, one can understand what he values. Alas! Since the four great schools of the Jin and Yuan dynasties, each has clung to a single aspect of Zhang Zhongjing's teachings, leading to mutual contradictions and a proliferation of divergent theories, resulting in the loss of a unified system. Since Ye and Xue, the tradition has nearly faded into obscurity. Mr. Gan was deeply troubled by this. Whenever he diagnosed and treated patients, he established the six meridians as the guiding principle, always striving to align with ancient practices. Thus, in his medical records, for chest impediment, he used Trichosanthes and Longstamen Onion Bulb; for water qi, Ephedra, Aconite Lateral Root, and Liquorice Root; for hemorrhagic syndrome with black coloration, he used Aconite Lateral Root to regulate the middle; for cold-dampness diarrhea, Peach Blossom Decoction; for dampness-heat, Pulsatilla Decoction; for yangming with insufficient bowel qi, White Tiger Decoction; for excess in the stomach and intestines, Stomach-Regulating Qi-Balancing Decoction; for jaundice, Gardenia and Cypress Bark; for yin jaundice, Aconite Lateral Root. Although the doses were often light, and sometimes ineffective for severe conditions, or even requiring five or six doses to achieve a slight effect, this was Mr. Gan's Way and technique, designed to avoid arousing suspicion and fear in people. I, being straightforward and stubborn, would rather hold onto Bian He's jade and Yongmenzi's qin, waiting for true appreciation, and have thus strayed far from Mr. Gan's teachings. Therefore, I have briefly outlined the main points so that those who read Mr. Gan's medical records may examine them.
