Both my wife and I have been teaching Reiki for over 11 years. What is funny is that while we only claim it will do those two things, we've had lots of people we've worked on claim that it would do a whole lot more. We've had clients claim Reiki to stop everything from headaches to help diminish cancer. That was their claim!
When receiving a Reiki treatment, the client gets to a deeply relaxed state allowing their body's own innate healing process to be accelerated. Sometimes the healing occurs in one session, sometimes it takes much longer, depending on the condition. We've found that when someone has Reiki done on them just after an injury, typically, the healing is very rapid.
When someone has a long standing condition, many times the client will require multiple sessions to allow healing to begin to occur. For more information about how Reiki can help you, just visit: http://www.reikimissouri.com.
We don't set out to try to convince anyone of the effectiveness of Reiki, we just let Reiki do it's work and let the results speak for themselves. Have a great day!
