Reiki is a thousand-year-old healing technique done by the laying on of hands. It is totally gentle, and you can do it to yourself, or to another person. In Reiki I, the different positions for direct healing to the body are taught. In Reiki II, the symbols of distance healing, emotional and mental healing are taught. Reiki III is the level of Mastery, which prepares the teacher to attune other Reiki healers to this energy. The faculty of channeling Reiki is passed from a Reiki master during an attunement process. It cannot be done merely by reading a book. The technique is extremely simple and powerful and can be learned easily. You only need the desire to heal yourself, or others. It does not require prior knowledge of any kind.
