It took me a long time, but I finally learned to trust my instincts or my feelings. I may not be right 100% of the time, but more often than not I can tell what/where the pain is located. The great thing about Reiki is that you don't have to send it to a specific part of the body, the Universe is very intelligent and will make sure the Reiki goes where it is most needed. I've also learned to avoid the tug-of-war when I think I should send healing energy to someone's shoulder but the Universe knows that some other part of the body needs the healing even more.
The Reiki Master who taught me said that she will teach my daughter or my granddaughter for free - and I think maybe next summer I'll take her up on that offer. My granddaughter will be 11 and she's already very intuitive and has always been very caring and helpful.
