Reiki

A colleague wants me to learn Reiki with her. I'm considering it if I can feel it. Reiki is a kind of healing force. I still remember back in LNUS, Mary Goh used her reiki towards me. I didnt feel anything at that time. I'm not sure it works only for those who believe. The course is only 6 hours in total, and it cost about 400 bucks. It's a bit costly for a 6 hr course.. but who knows reiki may work for me and I can use it to heal my friends, relatives and family. Anyway, I have to see if I can feel the force first bah.
