Human beings are energy systems. We suffer when we don't have enough energy to carry out our life functions or when we, as energy systems, are out of balance.
The effect of receiving a Reiki treatment is that our supply of life energy is increased and we return to balance. In this state of balance and renewed energy, we can heal.
A Reiki treatment consists of laying the hands on the body in a prescribed pattern and allowing the energy of life to flow through the hands to the person being treated.
