This therapy can be described as Universal life-force energy and it is channeled through the practitioner's hands for self-treatment or treatment of others.
I feel it's like being tucked away in a warm blanket of light, or as if I'm wrapped up like a cocoon. My teacher Norja mentioned "one hour of Reiki is like 3-4 hours of solid sleep". I have to say I agree!
The result of receiving Reiki is enhanced health and well - being on one or all of the physical, mental, emotional, or spiritual levels. I find it brings great balance to healing sessions, especially when used with crystal healing.
Many clients I work on comment that they think I'm holding their feet the entire time, which is a relaxing thought just on it's own. Note I am not holding their feet, but this demonstrates the power of Reiki energy and how a person can feel it in a physical manner.
I rarely perform hands-on Reiki, meaning I do not place my hands on directly on the body. I hold my hands a short distance (i.e. 6-8") above the person. This starts to give you an idea of how powerful a session can be when you think about the example above. If you have never experienced Reiki, now is the time!
