Yes, it would be the same as sending absent healing. Reiki originally comes from Japan and only became popular in the western world in the last thirty years. Rei ki means universal life force energy, ki meaning the same as chi or prana. The reiki energy is passed from reiki master to student by means of an attunement and at reiki level one the student can work on themselves, friends and family, after receiving the level two attunement they can work on clients and send the energy for distant or absent healing, in some types of reiki there is a level three and then reiki master level and in others just reiki master teacher level following on from level two.
What most people report from a reiki session is a feeling of calmness and relaxation, lessening of pain, some report sensations of heat or cold, some see colours or have visions. Some people feel nothing at all.
When i sent you reiki yesterday i sent you a symbol for peace so hopefully you felt more relaxed. Perhaps it would be better if we actually arranged a time for me to send it to you though, that way we will know whether you experience anything or not?
