Gestalt therapy is a system of applied humanistic psychotherapy that began development during the first half of the 20th century and was influenced by gestalt psychology, psychoanalysis, psychodrama, buddhist psychology, phenomenology, systems & field theory and quantum physics. His founder is Fritz Perls.
Since then gestalt therapy has prospered and evolved into a much larger and rich field of applied humanistic therapy. One of its main characteristics is its focus on the present and the development of awareness as the route to breakthrough and insight. Awareness, is an intermediate state in the process of the personal cycle of experience to bring resolution to incomplete "gestalts", that is, those shadows in the personal experience that have been left incomplete and remain in need of closure, in order to transition and evolve to the next stage in the personal development experience.
