Reiki works for the highest good of all.
                           Reiki "un-blocks" any and all impediments between what is organic and that which is "the original source of its life". Reiki transcends time and distance to heal and un-block impediments within one's past, present, and future. Reiki shifts the soul's emphasis from unwanted habits, in the benefit of fostering the achievement of one's personal goals.

History
                          Reiki is a verbal lineage passed down from Master to student through initiation. The student learns the history of Reiki, the Reiki lineage from the modern founder and Grandmaster Dr. Mikao Usui, to the present standing Grandmaster, Phyllis Lei Furumoto, and the student receives attunements. Attunements are spiritual agreements between the "other side" and the student that the student takes responsibility for being a conduit to channel the healing universal life energy.

Reiki Training is divided into three classes or also called degrees.  Reiki level one, level two, and level three (or Reiki Mastership).  You can be certified from an individual Reiki Master or a Reiki Master at a Reiki Institution. The three degrees include attunements to the Power Symbols. The signing of the power symbol activates the healing energy. Each power symbol activates a particular frequency of healing, one for physical healing, one for emotional healing, another for psychological healing. The Power Symbols appeared to Dr. Mikao Usui the day he received the power to do hands-on healing.  These Power Symbols originally appeared to him in Sanskrit then he translated them to Japanese (his native tongue). .
