It is open and available to people from every religious tradition. It is centered around the idea that in each of us there is an amount of universal energy. Ailments are caused by a lessening of this energy.
A healer has been trained in the art of attuning his or herself to this energy and is able to transfer it from their hands into the body of the one seeking treatment.
It is taught that Reiki energy is inexhaustible and also intelligent. This means that the location of the healer's hands is not as important as the ability to transfer the energy effectively as the energy will ultimately find its way to produce healing in the one being treated.
