To administer Reiki, a practitioner channels life force energy through his or her hands unto another. It’s said that the aforementioned spiritual guidance enables the Reiki to flow through the affected parts of the subject’s energy field and charges them with positive energy. It raises awareness in and around the physical body where negative thoughts and feelings are contained. This causes the negative energy—such as stress, anxiety, physical pain, sadness, confusion, etc.—to loosen its grip, allowing the touch of the Reiki healer to swoop in and clarify the energy pathways.
As previously mentioned, I’ve always been intrinsically drawn to the idea of energy healing—healing through means that aren’t able to be seen by the naked eye.
