The noble eightfold path wheel of dharma is the traditional symbol of Buddhism.
Zen Buddhism is a very unique philosophy/religion.
I had a dream that the symbol of Zen, instead of the enso, was the letter Z. Perhaps this only works in certain languages (Japanese, English, French, etc).
Either way, I dreamt of the letter Z, and as Wednesday was the anniversary of the Stonewall Riots (June 28, 1969), I decided to create this rainbow Z of Zen.
Enjoy & Happy Pride.
