Neurobiological research supports the fact that emotional memories and traumatic sensory experiences are stored in the limbic system and right hemisphere of the brain, along with non-verbal, sensory experiences such as images, body sensations, and emotions. Non-verbal therapies like sandplay are the most effective ways to access and release these “unconscious” feelings and experiences and bring them into consciousness, where they can be healed. Sandplay also provides a visual and non-verbal avenue for the psyche to develop and become whole. It is a direct method to establish an inner connection with the greater self, which Carl Jung encouraged as an essential step for healthy psychological development.
