The sky and earth on Japanese are "kenkon". "Ken" is sky, "kon" is earth. A circle
represents the sky; a square - the earth, symbolizing immensity of the sky and earth. The sky
corresponds to softness, earth - to hardness. The sign expresses harmony of hardness and softness in
a nature - sky and earth.
The Goju-Ryu meaning is directly connected to a sign as it also means hardness - softness. Go is
hardness, Ju is softness.
Chojun Miyagi is not excluded off because an idea is stated from the international point of view. But it
is necessary to explain, that the symbol inside a circle is a Miyagi family emblem, because the idea
of sky and earth, hard and soft was invented by master Miyagi.
