I love the fairies and divinities and trees and animals who do the healing in my space. At the same time, I recognize them as constructs of my consciousness, while I could just as easily be a construct of their consciousness.
Have noticed something interesting, though. Reiki happens when I lay my hands on, whether or not I explicity think of or speak of all the imaginary beings.
It's all really just play. You can do Reiki no matter what your belief structure, because it's a capacity that all living beings have.
In fact, it's great to be logical and skeptical. Don't believe it until you feel it happen. Get and give feedback. I try to teach simply, and be responsive to students' belief systems in any way that gets them to understand the basics. There is enough to learn in a Reiki Level One class, without adding in explanations of metaphysical worlds. And the metaphysics are not necessary, to practice and grow with Reiki. Just do Reiki.
It's always good for those of us who have practiced for a while, to be reminded of Reiki's simplicity.
Blessings,
