If you look closely at the Reiki kanji you will see a continuous movement between Heaven and Earth, no separation just unification, a never ending circle. Mediation is similar, completely connecting to the natural world.
There are many layers within the five elements, and exploring them and finding our own layer is an essential part of Reiki.
WATER quenches fire, produces steam, and gives us life.
FIRE burns away unwanted thoughts, givers us life by keeping us warm, produces dust which falls to the earth.
AIR enables us to breathe, giving us life.
SPACE or SPIRIT connects us to the Universe and our true nature.
EARTH, grounding and strong, powerful and living.
The five elements guide us, without them we wouldn’t survive, they are in many ancient practices and esoteric teachings.
