Reiki (pronounced Ray-Key) is a method of natural healing based on the application of Universal Life Force Energy (the name literally means Universal Life Force Energy).
While the typical Reiki practitioner opens a private practice, not all of us have what it takes to fly solo. It's possible to find a JOB in some kind of "healing" work, making it possible to fulfill the "being a healer" dream while receiving a salary from a company. In some cases one can work explicitly as a Reiki practitioner, but more often the jobs available require credentials in other healing modalities.
This site lists jobs not only in Reiki, but the known related fields in holistic or alternate health care.
If you are not already a Reiki practitioner, and are interested in this work, first get trained in Reiki.
