The Medicine Buddha is, as the name implies, the Healing Buddha. According to the legend, he transformed himself into a radiant blue light Buddha at a large gathering of people and taught/transmitted the knowledge of healing and medicine. Thus, he is often depicted with blue skin. In the traditional thangkas he is surrounded by various herbs and medicine, with halos of healing energy radiating from his head and body. As the Medicine Buddha's vow was to help heal all the sick and the injured, he is often called upon to help eliminate sickness. Usually the Medicine Buddha portrayed seated with a jar of medicine in his left hand, his right hand in the mudra of blessings, with a stem of a healing plant in between his thumb and forefinger. Sometimes the Medicine Buddha is also called the Blue Buddha, or the Lapis Lazuli Light Buddha. The Medicine Buddha mantra has powerful vibrations for healing, both mind and body healing.
