The Reiki energy is not sourced from the practitioner, but is an energy seperate from that of the practitioner's, coming from a source which is identified as that energy that runs through all things living and can be shared without depleting the 'giver'.
There is no religion attached to Reiki nor any belief system other than the unique appreciation of the gift of Reiki itself.
The positive energy that is Reiki can move stagnant or negative energy trapped in the body, which if left can cause illness and disease, replacing it with positive energy and allowing the body to heal and re-balance its' self as it needs.If the body has already become ill or is suffering disease, Reiki will help to re-balance upset energies clear stagnant energies and help the body to carry out repair and aid relaxation.
There is a unique feeling that comes with a Reiki 'treatment', each person and each session can be quite a different experience from powerful to gentle, but there is always something wonderful happens with Reiki.
