"Rei" means "Universal" and "Ki" (like "Chi") means "Energy". Reiki is life force energy. It flows through a person the way electricity flows through wires and it extends out from our bodies up to three to four feet. This energy is often described by both the Reiki practitioner and the Reiki client as a tingly sensation that produces soothing warmth. Reiki is very relaxing, flowing through the physical, mental, emotional and spiritual realms ....It has been some years now in which modern science has found that the entire universe , all matter as we know it , is made up of endless energy waves and frequencies moving through space. Reiki is a healing modality that gets in touch at that energy level in order to help the patient in healing and balancing their energy centers also known as the chakras. A person lies down comfortably, fully clothed, while the energy practitioner places her hands on or slightly above the body in specified areas. There can be massaging and or light tapping incorporated as well. It is a very pleasant and relaxing experience.
