I recently saw someone in a Reiki group tell another person that maybe they shouldn't be doing Reiki. Her reasoning? Because fear has no place in Reiki or any energy healing. I. Call. Bullshit. It is wonderfully healing and courageous to engage in healing practices in the face of fear.
Everyone experiences fear. Everyone learning a new modality experiences fear. And asking a question out of concern for one's health in the detox process that happens after receiving your attunement was a LEGITIMATE question, and not some unfounded fear based thing. It was a good question.
The real answer to that question is to trust that Reiki won't harm but help, and that the changes after an attunement (often called a detox) will not exacerbate pre-existing conditions. There are other things you can do as well to prepare for an attunement, like getting plenty of sleep, drinking plenty of water, eating balanced meals, meditations, walks, and even receiving Reiki from a friend, etc.
Having a pre-existing condition does not mean you can't do Reiki. Of course you can.
Having medical devices does not mean you can't do Reiki. Of course you can, you simply have to think of the medical device as part of your body so the device and body work together in harmony.
There is no reason to tell someone Reiki is not for them. It's for everyone. At the right time. At the place. By the right teacher. In the right moment. And that is for the student to ultimately decide.
You cannot rightly force Reiki on someone.
You cannot rightly push Reiki away from someone.
Reiki is the Universal Life Force Energy. It is in all things and through all things, and it is by Reiki that all things exist. We simply know how to harness it in ways for the benefit and benevolence of humankind and of all living things.
Reiki does not judge you.
It's okay to be afraid. It's okay to be nervous. This is why I use phrases like "Zen mode" because sometimes, I, a Reiki Master, am afraid too, and I have to set that fear aside in faith hope and trust (with a little bit of pixie dust) to get the job done anyway.
Reiki is for you. No matter what. I promise.
