Celtic Reiki is a variant of Reiki that draws energy from nature, particularly trees and plants, in addition to the universal life force. The early Celts believed trees had spirits and saw them as highly important. Celtic Reiki practitioners use symbols from the ancient Celtic Ogham writing system involving notches representing trees. Unlike standard Reiki which draws energy down from the crown chakra, Celtic Reiki draws energy up from the earth through the root chakra. During attunement, practitioners open to plant and tree energies and Celtic symbols to facilitate healing of mind, body and spirit.
