Being "moved" as you put it,having an "experience", "confirmation", or what ever represents the intellectual justification we give ourselves so that we can feel that our work in therapy and as therapists, has substance. It is a tricky game with ourselves and others that we Gestalt therapists play in trying to legitimize ourselves.
My confirmation as a therapist came many years ago, when I was in training with Marilyn Rossannes-Barrett, in NYC. As I watched her work with one of my fellow trainees, a feeling of sadness passed over me, just as I became aware of that feeling, the patient started to sob. I knew then what the work of therapy was all about: Be in touch with myself as I stay in touch with the patient. From the flow of my feelings comes the flow of my work with the patient. Less thought and more emotional inspiration. As was said by Hillel, about two thousand years ago, all the rest is commentary.
