Humanity cannot be reduced to a single symbol. Even if we try to draw the same "O," the brushstroke, the force we put into it, and our state of mind will be different each time. And its form will be completely different, just like our existences.
The "O" signifies the "Enso," a form with neither beginning nor end, symbolizing the Universe, the flow of time, and the connection between people.
It is also a circular window, a mirror that reflects our hearts. What we see through this circular window is our true inner "Self." Each person will draw a different "O."
Thus each "O" is accumulated to form a larger circle, representing the community. It is not merely an 'O'; it is Art created by a myriad of personalities.
