Harmony in Human Design refers to the correct relationship between the Design (the vehicle, the unconscious, the body) and the Personality (the passenger, the conscious mind). Harmony is not a state that is forced or achieved through mental effort — it emerges naturally when a being lives according to their correct Strategy and Authority. When the Personality stops trying to control the vehicle and the Design is allowed to follow its correct geometry, a natural harmony arises between what the body does and what the passenger observes. This is the foundation of a life lived in correct flow.
