Not everything has to pass through the needle's eye of language. Nonverbal elements of expression and communication are often accompanied by linguistic processes, but they contain meanings that are expressed in affects, gestures, and body movements, regardless. The analysis of physical interaction is a means to bring awareness to fears, injuries, tabooed needs, and the resulting self-restrictions. Peter Geissler aims to psychoanalytically explore the physical dimension between patient and therapist. He demonstrates the use of active techniques against the backdrop of the analytical reflection on transference and countertransference, while referencing implicit relational knowledge.
