Control your ungoverned tamper – a Zen Story

A Zen student went to Bankei and said:”Master,I have an ungovernable temper.How can I cure it?”
“You have something very strange,Show me where it is?” asked Bankei.
“Just now I can’t show it to you” said the student.
“If not now, when?” asked Bankei
“It arises unexpectedly,” replied the student.
Then,” concluded Bankei, “it must not be ur own true nature. If it were, you’d show it to me any time. When you’re born, you did not have it,and your parents did not give it to you. Think that over.”
