In addition to the common TCM patterns Chad has mentioned, there is another layer you can also consider and that is role of the five shen.
A lack of will is a characteristic sign of the hun being impaired. The movement of the hun is key to stimulating the shen, which in turn provides a clear and conscious awareness. When the hun slows it’s movement depression and especially low desire/lack of ambition result. Since the hun stimulates the shen, it is also common that shen disorders result in chronic hun conditions, which include anxiety, fearfulness, and insomnia.
The hun is the ethereal component of the liver system. Generally liver qi stagnation is the main cause of impairment of the movement of the hun, though liver blood deficiency could also be a cause. The main points to stimulate the movement of the hun would be GB 40 and UB 47.
As you progress through your learning of TCM you’ll find there are many different layers and viewpoints to any given set of symptoms and conditions.
