It is energy that must be “tuned” to the person it is being sent to. Once it is “tuned in” it will flow through the energy currents that exist naturally, just the same way that a phone signal or wifi signal does. Distance is no object for it, just as it is no object for the internet or phone communications. The energy that surrounds us carries all of these energies to the intended receiver. With Reiki, the practitioner is the conduit of the energy. It can be a difficult concept to understand that our thoughts, intentions and emotions are energy. Yet most people can feel that their emotions create an energy sensation in the body. They may also understand that the nerve endings and spinal cord help to carry these energies throughout the body. If you go one step further, you can see the relationship between our thoughts and our emotions. It’s not much of a leap from there to see that our thoughts and emotions have an effect on our perceptions and the people around us. These things truly change our environment! It is all energy.
