A Heart Full of Great Compassion

Known in China and abroad as the “King of Medicinals,” Sun Simiao 孫思邈 is one of the most celebrated figures in the long history of Chinese medicine. He is also the author of China’s first – and still relevant – essay on medical ethics and professional cultivation, which is included in countless oaths of TCM schools worldwide. Despite Master Sun’s elevated status in both China and the West as one of its greatest practitioners, however, an official biography composed several centuries after his death and other historical documents offer not a single hard fact about his professional practice as a physician. To appreciate the significance of this fact, we need to look both at the context of medical practice in early China and the content of Sun Simiao’s teachings. With this understanding, we shall be prepared to read his famous essay “On the Sublime Sincerity of the Eminent Physician,” which I have translated below.
