REIKI as a Definition is Literally Life Force Healing Energy...Speaking in(word) entymological terms...The Healing Power or Source is of God...Think of Jesus and His Amazing Healing Powers--THIS is EXACTLY REIKI only I do not know what NAME was ascribed or assigned to His Abilities...I Believe Jesus is MY Holy Spirit. ANY other spirits I might listen to??? GEE I Rather Like Archangel Raphael--of the Light, and Archangel Michael--protector, and Archangel Metatron--who is the Supreme Archangel sitting at God's right hand!!! Do I use Spirits??? GOT JESUS???
