I am Japanese, REIKI is my everyday life. My Mom used REIKI every time I was sick just like we use home remedies to cure instead of take medication. Everyone able to do REIKI if you can focus on Oneness, connect to Universe, have gratitude for life, Ancestors. Original Reiki was Developed by Mikao Usui by twenty-one day Buddhist training course held on Mount Kurama It is not known for certain what Usui was required to do during this training, though it most likely involved meditation, fasting, chanting, and prayer. So there was no school, he was never did so called ""attunement"" to be Reiki master or teacher. If you meditate everyday, focus on connection and balance of your energy to Universe, you feel energy come from your hand. Try use the energy to heal your self first, then try to change food taste, water taste, family, friends. It's sad to see we are so busy to proof or things need to be so logical in western culture. If anybody think Reiki is not real thing, you should try do to your self then it really change your life. You got everything you need within you. Love
