What training will a Reiki Practitioner have had?
There are three levels of Reiki – Reiki I, Reiki II and Reiki Master.
It does not necessarily follow that a Reiki Master will be “better” than a Reiki I practitioner.
A practitioner who practices regularly, giving treatments to others and themselves may be a more powerful healer than a Master who does not use Reiki on a regular basis.
