Hi, Wendy!
reiki.org has a good discussion of the reasons why reiki is not in conflict with any religious practice.
Pollysis: yes! Yes, insurance. I know the Canadian association offers insurance, and I'm sure we have something here in the States that offers it, too. Thanks for the reminder. There's a lot to remember, but fortunately I'm not on a strict timetable, so I can take a little time to think things over.
