Belief in Reiki

My clients often have a baffled look on their face when they experience Reiki working through their life issues or health conditions instantaneously. It's like seeing for yourself that the world is round not flat when all you've been told is that the world in flat. Previous beliefs are challenged and we are forced to believe there is another possibility to our otherwise fixed and set thought patterns.
I was taught in Reiki level one that is not necessary to believe in Reiki to benefit from it, but beliefs are the starting point of choices and how we create our own reality. The new breakthroughs in science say that it is your thoughts and beliefs that control your life. Bruce Lipton says that 95% of the control of our cellular biology stems from our perceptions of our environment, while only 5% is from our genes. He also says that only 5% of our lives are run by our conscious mind while 95% of our perceptions governing our life are subconscious.
With one positive experience of receiving the benefits of Reiki, the mind knows that Reiki energy is at least a possibility to revisit and find out again if what happened really can happen. As we move into working with Reiki further, we become more and more of a believer through our own experiences of it working in our life and the lives of others. Still though, we are constantly surrounded by and influenced by a greater common belief that its not really real.
If we create our own reality, then living in a world where Reiki is not a side dish on the menu but the main course meal can be possible. That is, if we believe it.
