Reiki is a complementary health approach in which practitioners place their hands lightly on or just above a person, with the goal of facilitating the person’s own healing response.
Reiki is a Japanese technique for stress reduction and relaxation that also promotes healing. It is administered by "laying on hands" and is based on the idea that an unseen "life force energy" flows through us and is what causes us to be alive. If one's "life force energy" is low, then we are more likely to get sick or feel stress, and if it is high, we are more capable of being happy and healthy. The word Reiki is made of two Japanese words - Rei which means "God's Wisdom or the Higher Power" and Ki which is "life force energy".
So Reiki is actually "spiritually guided life force energy."
