Ego has no place in healing. It is possible to accomplish greats feats of healing with Reiki, but taking credit for the healing promotes the growth of ego. Ego creates blocks in the Chakras. A Reiki practitioner must present as a clear and open channel for the energy. When ego intrudes, judgment enters and there is no place for ego in healing work.
The biggest error Reiki practitioners make is believing it’s them doing the healing and not the energy. It’s not you; it’s the energy. The energy exists in perfection and will go where it needs to go, no matter what the practitioner does. I’ve seen practitioners waving their arms around and doing all sorts of dramatic movements, but the truth is that Reiki can’t be done wrong and it can’t be controlled. The practitioner is merely a channel for it. Try to be a pure and open channel. Reiki energy is Divine in origin; it exists in perfection.
Reiki mastery should never come from ego. As I tell all my students, “I don’t care if you raise the dead, it’s still not you.” And so it is true that the healing comes from the energy both within the client as well as the Ki that exists in the universe and is channeled by the practitioner. The practitioner is merely a channel, “an empty bone”, as the saying goes. So the ego has to die; if not by willing it away then by uncomfortable situations that the Universe (or God, or Goddess) will throw at us to make us learn this difficult lesson. The Universe ever conspires to do battle with the ego. These are our “lessons”, uncomfortable to downright miserable events that come into our lives to help us to learn and grow. And thus, the need to “heal the world” comes from compassion, not ego.
