The Reiki Degrees are broken down into 3 levels. The first attunes you to the Reiki and allows you to channel it through you, the second gives you symbols to work at a deeper level and the third allows you to tune another.
Reiki 1
This is the first level of Reiki, you receive 4 attunements over a period of 2 days and are given instructions on the history of Reiki, how we apply it to the body of ourselves and others and how it works.
Reiki 2
The second degree of Reiki is where we take Reiki from the hands to the mind. Your are given another attunement during which time you will be attuned to use the Reiki Symbols. 3 Symbols are given, one to increase the power, another to heal the emotion aspect and the last is the most power symbol of all. The Symbol that sends Reiki to anything you can imagine.
Reiki 3
The Third degree of Reiki is called the Masters degree but that name is overly implied. During this attunement you are given the master symbol which allows you to attune others.
