The Xin & Yi combine, the Yi & Qi combine, the Qi & Li combine, are the Internal Three Harmonies. The Hands & Feet combine, the Elbows & Knees combine, the Shoulders & Hips combine, are the External Three Harmonies. These are the Six Harmonies. The left hand & right foot mutually combine, the left elbow & right knee mutually combine, the left shoulder & right hip mutually combine. It is also thus with the right’s combination with the left. Additionally, the Head combines with the Hands, the Hands combine with the Body, the Body combines with the Steps, which are not included in the External Harmonies. The Heart & Eyes combine, the Liver & Tendons combine, the Spleen & Muscle combine, the Lungs & Body combine, the Kidneys & Bones combine, which are not included in the Internal Harmonies. How? Yet they are still nothing more than the Six Harmonies! Thus, these are unique distinctions regarding this subject. In every case, when one moves then there are none that are motionless, when one combines then there are none that are not combined. In all cases, the usage of the Five Shapes & Hundred Bones of the body are included among these.
