Kekki
Kekki provides the body with "nourishing strength" and means "ki of the blood". It is used by the body's cells in order to maintain its substance and have energy. Kekki is the least structured energy in the body. It is the nourishing energy, the vital force, needed to create. It is the essence of our being.
Shioke
Shioke provides the body with the structure in which kekki can work and means "ki of the salt/minerals". It helps hold together and uses will to achieve its purpose. It is the human force field. It represents the constitution of human beings, our possibilities of self-realization, and our boundaries. It is the vessel in which kekki is stored
Mizuke
Mizuke allows relationships to function as the basis of communication and means "ki of the waters". Mizuke is emotional energy, including sexual energy. It supports the metabolism and allows us to take in nourishment in many forms. It is energy that allows the structure of shioke to move beyond. In other terms, Mizuke is the force where shioke is the form.
Kuki
Kuki energy sets the boundaries and restrictions and means "ki of air". It is self-fulfillment and helps us shape our lives and our goals. It provides the ability to think logically and provides motivation to follow our own path. At the same time, it makes sure we do not divert from our path or become misguided by others. It also allows us to harmonize with those around us, especially those we are close to. It is, in other words, our true will.2
Denki
Denki manages our relationship with the ego and means "ki of thunder". It allows us to grow while being considerate of others. It provides us with an ethical and moral basis in which to guide our actions. It shows us the proper attitude for each individual situation. Denki creates a natural fairness in exchange with others and tolerance.
Jiki
Jiki provides us with our complementary or shadow self and means "gathering force or magnetic power". Jiki allows us to develop our skills and talents regardless of whatever else we undertake. It forces us to pay attention to what we need to develop and provides the structure for it. Jiki represents the power of aesthetics, art and beauty in any form.
Reiki
Reiki organizes the correct synergetic application of the other forms of ki in the body. Reiki in this system means "soul force or spiritual power". It is the energy in the body that is closest to the "divine creative force". It provides the source of all life. It helps attune, cleanse, and balance. Reiki promotes all life processes. Reiki is the means by which shinki can work in the body.
The highest form of KI is known as SHIN-KI, which is the DIVINE KI and Source of REI-KI. Reiki is the highest, purest form of ki which is available to a living being alive on earth (like people, animals and the like), all aids in he organization and harmonizing of all other forms of ki. The reiki attunement and the process of reiki healing clarifies and harmonizes all other forms of ki and our consciousness, leading us closer to the Divine Source and elevating ourselves as spiritual beings alive on earth. To use an analogy, think of the SUN as the Source/Shin-ki and the light and heat and all other energies which the Source/Shinki emits is the Reiki- this is the direct connection to the Source/Shinki which the REIKI ATTUNEMENTS activate allowing for the reiki healing process to work- a divine gift which the Universe bestowed upon the Founder who then in his wisdom and compassion he passed on FREELY.
