The colors derive from the solar prism each having a different wavelength, which over an energetic plan, has a direct influence on our body and our psyche. In Kin-Jo, we use these vibrational frequencies to activate the blades of each wheel.
What is a blade? All researches in energetics and more specifically in acupuncture, show an energetic reality in correspondance with all parts of the human body, the physiological functions and the organs. In Kin-Jo, this energetic reality, though virtual, is called Blade. Each Blade is associated with a color and a sound.
What is a Wheel? In the first two levels, we call Wheel, the group of four Blades which revolve around the "Intersect point", an energetic point at the sternum.
