 Desires are harmful to both body and mind, as Ji Kang emphasizes in “On Nourishing Life.” Purity of being, in contrast, entails the absence of desire or any form of emotional disturbance. Are all desires, then, unnatural? The essay drew a sharp response from Xiang Xiu, for whom desire arises naturally from the mind. As such, it cannot be eradicated but only regulated by rules of propriety and ritual action. In reply, Ji Kang points out that although pleasure and anger, and the desire for fame and beauty may stem from the self, like a tumor they only serve to deplete one’s qi. Basic needs are of course not to be denied, but desires are shaped by objects and reflect cognitive distortions that consume the self. To quench one’s thirst, one does not desire to drink the whole river. This is fundamentally different from the desire for power and wealth, which knows no rest. Moreover, the suppression of desire by artificial means may remove certain symptoms, but it does not cure the disease. It is only by recognizing the harmful influences of desire that one begins to seek calmness and emptiness of mind. Ultimately, nourishing life is not just about health and longevity but sets its sight on a higher, and to Ji Kang, more authentic, mode of being characterized by dispassion.
