- Congruence

Congruence refers to the energy flowing freely between systems that are compatible in patterns and rhythms and attuned to each other. Congruence is fully realized only in an overarching universal order that is reflected and detectable in nature and its systems, including human beings. It cannot be examined with scientific means. As disharmony and tension are inherent in most interacting systems, congruence remains an ideal rather than reality. 

Humans experience the presence of congruence as a sense of well-being and its absence as negative feelings, designated as Anxiety. In this framework, anxiety, therefore, includes various emotions, such as anger, guilt, restlessness, or depression.
