Which symbol in the association flag represents brotherhood and unity?

The red circle in the association flag symbolizes brotherhood and unity. It serves as a representation of the cohesive bond that exists among practitioners of the martial art. The circle itself signifies completeness and inclusiveness, reflecting the idea of coming together as one community. This imagery is significant, as it embodies the principles of unity, friendship, and collective strength shared by those who practice.

Though other symbols have their meanings—such as the flying side kick which represents skill and martial arts ability, the stars denoting achievement and guidance, and the tenets highlighting the core values and philosophies—none encapsulate the theme of brotherhood and unity as effectively as the red circle does. This reinforces the importance of community and support among martial artists, fostering an environment where collaboration and mutual respect thrive.
