The three internal Dahn-jons are defined by the roles they play. The lower Dahn-jon acts as the fuel tank in which energy is stored for circulation throughout the body. When your lower Dahn-jon becomes strengthened, the overall energy balance of your body will be restored, amplifying your natural healing power. You will exhibit more patience and drive, developing a stronger sense of self-confidence. Red is the symbolic color of the lower Dahn-jon.

The middle Dahn-jon is associated with control of the energy. It is located at the exact center of the chest, between the breasts. Because emotional energy is controlled at this point, strengthening of the middle Dahn-jon will impart a peaceful and loving feeling. Blockage of the middle Dahn-jon, which can occur due to negative emotions and stress, can have an undesirable effect on the nervous system, leading to many different diseases. The color of the middle Dahn-jon is gold.

As Ilchi Lee writes that the upper Dahn-jon is equated with the spiritual aspect of our existence. When the upper Dahn-jon is strengthened, our spiritual ability awakens and we feel a connection with the divine energy of the cosmos. Blue violet is the symbolic color of the upper Dahn-jon.
