REI is the universal energy that is in all places and objects, and KI is the vital energy that flows through all living beings.
  Through gentle positioning of the hands over the major energy centers of the body (chakras), which are also connected to the physical organs, the reiki master channels and transmits the Universal Energy.

  That practice unlocks, balances and harmonizes these energy centers and complements the treatment for physical healing. It is a complementary therapy in the Usui System of Natural Healing. Its rediscoverer is Mikao Usui.
