While a one-off Reiki treatment will do something beneficial for you, bringing a sense of calm and peacefulness, and maybe producing some short-term physical benefits too, the best results come through having a course of treatments, maybe 4-6 sessions at weekly intervals.
The effects of Reiki build up cumulatively: therefore having a course of treatments helps to produce long-term beneficial changes for you on many levels
Reiki is not a substitute for medical treatment. If you have any symptoms of illness you should see your doctor.
Reiki is safe and will complement any form of complementary or medical treatment.
A Reiki practitioner will not diagnose or recommend any form of treatment.
