“Deceiving yourself shouldn’t make logical sense. After all, lying involves telling someone something you know to be untrue. When you are both the liar and one lied to, this means you have to both know the truth and not know the truth. In practice, that means willfully disregarding key knowledge to arrive at a conclusion that is more convenient than what the facts appear to suggest.”
Yamaoka Tesshu, as a young student of Zen, visited one master after another. He called upon Dokuon of Shokoku.
Desiring to show his attainment, he said: “The mind, Buddha, and sentient beings, after all, do not exist. The true nature of phenomena is emptiness. There is no realization, no delusion, no sage, no mediocrity. There is no giving and nothing to be received.”
Dokuon, who was smoking quietly, said nothing. Suddenly he whacked Yamaoka with his bamboo pipe. This made the youth quite angry.
“If nothing exists,” inquired Dokuon, “where did this anger come from?”
