 Therefore, a person must leave behind the activity of sense and reason and enter into spiritual union with God.Through spiritual union with God (theosis), the mystic is granted theoria and through this vision is ultimately given knowledge of God.In the tradition of Dionysus the Areopagite, theoria is the lifting up of the individual out of time, space and created being, while the Triune God reaches down, or descends, to the hesychast.
