To use Reiki you need to be attuned.
An attunement is a traditional spiritual ceremony that helps you to connect to the Reiki Energy Source. It’s a new rebirth. Many things may or may not happen during and after an attunement. An attunement is awareness of our self-empowerment.
The attunement is all you need to use Reiki energy in your own life and for those around you. A Reiki Master Teacher does this attunement.
