Spiritual healers often supplement their healing work with color healing. As they lay their hands on the patient, they mentally direct specific color rays into the patient's aura and body. These methods of using color in healing point to our basic contention: color does impact the human aura and, consequently, the human body. Yellow helps strengthen the nerves and the mind. It helps awaken mental inspiration and stimulates higher mentality. Thus, it is an excellent color for nervous or nerve-related conditions or ailments. Yellow can be used for conditions of the stomach, liver, and intestines. It helps the pores of the skin and aids scarred tissue in healing itself. It also has a very enriching effect upon the intellect and the brain. Like the color of gold, yellow represents the highest of the physical colors. "Worth its weight in gold" applies to yellow.
