Anyone who can relax and meditate can use visualization, by telling a story to the body in pictures and creating a drama for the white cells to enact. The white cells circulate and keep us healthy by reacting to bacteria, viruses, and other infective organisms of all kinds. They also have to do with allergies, with vaccinations, and with resistance to cancer. Immune cells learn to recognize invading organisms, and they specialize.
