The question that has come up is this: Does Reiki continue to work on the client or on myself when I stop the session? In the past, I have taught my students and told my clients that it continues to work for hours, days, weeks, even longer after a session, like a ripple effect. I may be changing my tune.
Others have said the Guides, Angels, etc. who work in concert with you when you channel Reiki continue the healing after the session itself stops. I am able to connect to my guides easily and that is not what I am getting. The Reiki energy that has been introduced into the body during the session may continue the healing, not any guides, angels. etc.
For those of you who don't know, everyone has a "Spiritual Team" that is theirs and theirs alone, which consists of Spirit Guides, Angels, Archangels, Guardian Angels, and perhaps some Ascended Masters or Master Teachers who are drawn to work with them because of what they do, or are trying to do with their life. These change many times during your life time as you go through different phases of your life, so whomever or whatever you need at specific times is working with you.
When you do some form of healing work like Reiki, you have special Guides, etc., that work along with you to protect, guide and even assist you during the session, on yourself or others. Some people believe with their intention, that they can direct some of their team to continue to work on the individual or self even when the actual session has stopped. However, this keeps the practitioner "tethered" to the client energetically, which is not particularly a good idea.
After a Reiki session, we are taught to do one of several things to disconnect energetically from our client, either to run our hands under cold water (possible even up to our elbows) to break the energetic connection to the client, or to perform a technique called "Kenyoku" or dry brushing (a Buddhist technique for clearing the energy field).
So if you intend that the energy continue to work on your client even after the session has ended, you are continuing the energetic connection to them, which is definitely not a good idea.
