Basically. Reiki is both the name for the Universal Lifeforce Energy as well as the name of the method for harnessing it for healing or wellbeing.
So kinda like the Force then..
As a massage therapist, I learned it to incorporate into my sessions. The best massage combines all techniques needed for the client. Being "in touch" with a client's energy is quite helpful in getting the desired result.
I never heard of it.
I practise it on myself and others. It’s a gift, not my profession.
I think it's like message therapy, but not sure.
In college I knew a guy from Turkey named Sultan Reiki.
I found out later that there were so many guys from middle eastern countries because their families had lost power. They had money to support them in college, but they would be promptly murdered if they tried to return home. So they stayed in school and changed their major every few years.
Reiki: Studied it, got my 2nd degree, practiced it, don't believe in it other than it being positive thought.
