Reiki is the source power of the universe, the thing Albert Einstein was looking for and hoping to identify as a mathematical equation. Reiki heals because it is unconditional pure love.
Reiki practitioners are trained to channel this pure love for healing. Reiki I practitioners have the ability to heal the physical body. Reiki II practitioners can heal not just the physical body, but the emotional and mental body of a person. Reiki II practitioners can also perform distance healing for a person in another location. Reiki Masters can heal the spiritual body along with the other three bodies, which warrants a Reiki Master to be the most powerful of Reiki healers.
Dr. Usui, who uncovered Reiki in the early 1900’s, proclaimed that all dis-ease comes into the spiritual body first, and then manifests as physical illness.
