Reiki (pronounced "ray-key") has its origins in Japan. 

The word "reiki" means ‘universal life energy’ in Japanese.   Reiki is based on the premise that illness is caused by a disruption in the body’s energy field or life force.  

Reiki can help to heal by charging negatively affected parts of the energy field with positive energy.   Energy fields in the body each have different vibratory levels and Reiki practitioners use their hands to affect and hopefully rebalance these vibrations in the negatively affected part of the body.

Treatment is carried out fully clothed and is said by many people to be very relaxing.
