What effect can horses develop in a setting based on depth psychology? In moving conversations with patients and therapists, Birgit Heintz gains insights into the fascinating work with horses. The author frames her very personal perspectives with current findings from neurobiology and infant research as well as the evolutionary history of empathy. She describes in detail the phenomena of resonance and influences on the transference process in the relationship triangle therapist - horse - patient. This in-depth insight into the practice of horse-assisted psychotherapy is a must for all those who are interested in both the psychological relationships and the nature of horses.
