My wife practices Reiki
(Her first post here:
Reiki in Basel - though, we live near Lucerne now, not in Basel).
All the patients she has have experienced a very positive change in their physical conditions after the treatment, and regularly come for treatment, or have also learnt themselves so that they can treat themselves or their family.
What was mentioned before about passing the "negative energy" from the patient to the healer is true, so my wife avoided giving treatments when she was pregnant, for example.
Anyone interested in a trial session near Lucerne, can contact her.
