Rei-ki is a japanese word, that means «universal vital energy». it’s the force that acts and lives in every living element. Rei describes the universal and unlimited aspect of this Energy, and ki everybody’s own Energy (also called chi in China or Pana in India). The two words added altogether make Reiki.
