Ji 幾 is always the almost imperceptible beginning of movements of the mind or body that determines the direction of the course of events. In the Book of Changes (Yijing), the pervasive beginning is a profound insight into the changes of everything, it is the first emergence of good fortune.
The art of the great practitioner lies in the ability to grasp these passages, to perceive the imperceptible beginning of a disorder and to anticipate its possible development by correctly understanding the smallest signs. Then one can make a subtle diagnosis and treat it before the disease becomes deeply entrenched.
