Using case study material and neurobiological research, this paper aims to demonstrate the unique, non-verbal conversational value of the arts-based medium of sandplay therapy within the context of the psychotherapy process. By offering a free, but protected space in which to work symbolically, sandplay (as opposed to sandtray, or expressive arts therapy) enables clients to access unconscious material that language often cannot reach. When handled non-directively, without interpretation, and with delicate, conscious words – or with silence – on the therapist’s part, sandplay effects profound levels of healing, enhancing the more traditional talk of therapy.
