Traditional Usui Reiki Symbols

Reiki symbols are basically Sanskrit derived Japanese forms that help improve the flow of
Life Force Energy. These symbols are an essential part of Reiki practice and they used to be secret and revealed only to Reiki students who are initiated into the advance or master level. However, with the technology available today it's hard to keep anything secret :), so information about them can easily be found on the internet. Although these symbols do not have any special power in and of themselves, using them after attunement helps a practitioner focus the Reiki energies. The primary three symbols used in traditional Reiki are Cho Ku Rei or the Reiki Power Symbol, Sei He Ki or the Emotional and Mental Healing Symbol and Hon Sha Ze Sho Nen or the Distance Healing Symbol.
