Attunements
If you study Reiki with a Western trained Reiki Master you will go through a series of ‘attunements’ as part of your training programme. There are an enormous number of different variations within each tradition.
Attunements are the procedures which Western Reiki masters use to connect their students to Reiki Energy at Level 1, to three Reiki Symbols at Level 2, and to the Master Symbols and various other symbols at Level 3. Each level has a prescribed number of attunements attached to it depending on the tradition being taught.
Attunements are for life. Once you have received the attunements at a given level there is no need for them to ever be repeated. However some students like to have them repeated and there is no problem with this.
