Yamaoka Choshu, a young disciple of Zen, visited one teacher after another.
One day he came to Dokuonu.
Wanting to show their knowledge, he said:
- Mind, Buddha, sensual Existence - they do not really exist. The true nature of phenomena - emptiness. There is no incarnation of deceit, nor wisdom, nor mediocrity. Nothing is impossible to give, nothing can take.
Dokuon who calmly smoked, did not say anything.
Suddenly he swiped Yamaoka's head. The young man was very angry.
- If nothing exists - Dokuon asked - where does this anger?
