Ok ......so what is Reiki?
I can do no better than to give the same account as Reiki 'guru' Penelope Quest who describes it as follows:-
Reiki is a safe, gentle, non-intrusive hands-on healing technique for use on yourself or with others, which uses spiritual energy to treat physical ailments without using pressure, manipulation or massage; however, it is much more than a physical therapy. It is a holistic system for balancing, healing and harmonising all aspects of the person - body, mind and spirit - and it can also be used to encourage personal and spiritual awareness and growth.
