Her publications include "Don't Push the River (It Flows by Itself)", a first-person account of Stevens' investigations of Gestalt therapy. It shows the author during a period of several months in association with Fritz Perls at Perls' Gestalt Institute of Canada at Lake Cowichan, Vancouver Island, in 1969. Barry Stevens describes both Gestalt therapy theory and practice and her relationship with Fritz Perls in a sensitive way, thus creating a vivid image of Perls in the last months of his life.
