Reiki (pronounced Ray Key) is an ancient non-invasive hands-on healing technique rediscovered by a Japanese Buddhist by the name of Mikao Usui in the 1800's.
The art of Reiki was long considered secret by Tibetan and Japanese Masters who taught their disciples of healing. As it was introduced in the Western culture it quickly became a popular practice, for anyone who desires to help themselves and others can learn Reiki.
The word Reiki means "Spiritually Guided Life Force Energy". It can be understood by some as the Holy Spirit, by others as the Universal Consciousness. No matter what your belief structure, sharing Reiki is sharing love.
