It also works on an emotional level. Some people may have a tendency to get depressed or just not feel emotionally balanced, and after receiving a few Reiki treatments they begin to feel more emotionally stable. Often, after about the third or fourth session, the emotional level opens up more strongly and people sometimes start to laugh or cry. It means expressing what has been underneath. Reiki brings out the emotions that have not been allowed or expressed.
Every wound has to show up, be exposed in order to be healed.
For some people this can be uncomfortable. I once gave a woman a session, and after the first treatment, she felt very emotional, and felt a lot of anger come up. So of course, this can be disconcerting, but these feelings are part of the healing process. When I explained this to her, she continued to come for treatments, and after the third treatment, everything changed and she felt more in balance with her emotions. Then there is also the mental level.
