Do you have to be licensed to practice Rekei? -

You will need to google your state and Reiki Laws to know what your state requires. Here is a good general website: http://www.reiki.org/reikinews/reikin5.h... Licensed by whom? Its not as if the AMA approves of it, so I do not see who is gonna stop you unless you get sued by someone for making any claims about the benefits of Rekei.
