The first benefit is relaxation and letting go of stress and anxiety. Whether you are a skeptic of it's healing properties, anyone can relax. With soft meditation music, low lights, and candles, any Reiki session can help relax you and let go of the day's stress.
At Serendipity Meditation Center, they use either meditation music, or guided audio meditation that help you work through issues while you are receiving Reiki. For example, letting go of anger, forgiving yourself and others, or learning to love yourself.
When your body is relaxed it can begin to heal itself and also allow you to sleep again if you have problems sleeping
The second benefit of Reiki is to heal the body. Reiki helps boost your immune system, ease pain, and help other medical healing methods. There has been multiple scientific studies where patients have been given Reiki.
There are also hospitals like the Cancer Treatment Centers of America that use Reiki in conjunction with western medicine.
And thirdly, the intuitive and spiritual benefits are often overlooked. Reiki relieves energy blocks to chakras thus releasing the energy to flow freely to help you balance your mind, body, and soul.
Many who are spiritually focused have found that Reiki allows them to connect to their higher self or spiritual deity and know where to give Reiki as well as help the client with other emotional issues as well.
