The Usui Reiki attunement process used five reiki symbols. As said earlier, Reiki symbols are not the Reiki itself, but they help you increase a certain aspect of the Reiki energy. More precisely, Reiki symbols are keys of the Universe that open the gates to the spiritual dimensions. Reiki is generic term made up of two Japanese words (Rei means “God’s Wisdom or the Higher Power” and Ki is “life force energy”) that describe many types of healing and spiritual work. The term Reiki is not exclusively related to the healing system based on Dr.Usui’s healing method, as this is called the Usui System of Natural Healing.
