A Reiki Practitioner is anyone who has been attuned and trained to any level of Reiki. The levels start at Reiki I. That first attunement gives you the Reiki Practitioner title and the ability to be a clear and perfect channel for the Reiki energy to flow through. It matters not what lineage, what level, how long it has been since you last provided service to be a channel or what confidence level you have, you are a REiki Practitioner. Attunements are best received in person and training makes all the difference in the world as to the effectiveness and clarity of sensitivity development.
