Zen Buddhism uses the ensō (円相, , “circle”) to express a moment when the mind is free to let the body create.  The circle is sacred and symbolizes absolute enlightenment, freedom, the present moment, strength, elegance, and the universe.

The circle is open because it is incomplete, which allows for movement, growth, and development.  This openness invites for the beauty of imperfection of all things.  The circle can also be depicted as a closed figure.

The symbol ensō is usually brushed in one stroke, in black ink, using calligraphy.  I chose to create this symbol in gold and in the open form to represent the enlightenment illuminating the black (darkness).  When your mind is free, you are illuminated, and your inner light within shines.
