Reiki is a Japanese technique for stress reduction and relaxation that also promotes healing. It uses a technique commonly called palm healing or hands on healing as a form of alternative medicine and is sometimes classified as oriental medicine by some professional medical bodies. Reiki practitioners believe that they are transferring universal energy (i.e., reiki) in the form of qi (Japanese: ki) through the palms, which they believe allows for self-healing. If one's "life force energy" is low, then we are more likely to get sick or feel stress, and if it is high, we are more capable of being happy and healthy. "life force energy" is transferred through Reiki to promote healing.
There are two main branches of Reiki, commonly referred to as Traditional Japanese Reiki and Western Reiki. Though differences can be wide and varied between both branches and traditions, the primary difference is that Westernised forms use systematised hand-placements rather than relying on an intuitive sense of hand-positions (see below)
