The book presents forms of Gestalt therapeutic cooperation that invite clients to structure their perception, encourage and challenge them, while leaving them their freedom. It also addresses the therapist and their willingness to engage in boundary experiences. This book, which has emerged from years of practice, aims to make methodological aspects clear and practicable. The therapist will find a variety of tangible aids for implementation. Through case studies and commented session protocols, readers will recognize what makes Gestalt therapy effective. "I would like the book to be understood as a manual for practitioners, containing insights and examples of application regarding aspects of Gestalt therapeutic cooperation that have proven effective in dyadic Gestalt therapy." (from the foreword).
