I wonder why my hands sometimes feel hot and tingly, and other times cold - and also why the client's perceptions of heat and coolness sometimes differ from mine.
I also wonder about my perceptions when my hands are on the client. Sometimes I feel pulsing or throbbing, sometimes I have the sensation of chunks or packets of energy. Sometimes when I feel nothing, the client is nearly overwhelmed with sensations. Odd.
I don't know how reiki works. It's supposed to help people feel better. Most people who try it seem to like it.
