There are 7 practitioner levels (A levels) and 3 teacher levels (B levels).
There are also 7 Reiki symbols on which the system is based.
Reiki is not a way of life but merely a tool to boost our supply of life force energy and to clear our baggage to allow more peace and health on our journey.
The association of the 7 level system of Reiki was set up in Sydney in 2004.
