Using your sense of sight when anxiety and sensory overload become too much is a helpful tool to ground yourself in the moment. Gently direct your awareness to what you see through our rainbow-creating prism. 
 
When white light passes through a prism, it bends due to refraction, the process of bending light as it moves from one medium (air) to another (glass). Allow the prism to mesmerise and calm you. Feel your breathing slow and relax while you watch the play of light and shadows.
