The story goes that when the student expressed concern about his own bad temper to his master, the master said, “Show it to me.” Of course, the student couldn't and explained that it wasn't within his control to produce it at will, but rather it just happened. The master replied that if it wasn't within his control, then it was not part of his true nature. From that point on, whenever the student felt anger welling up inside of him, he recalled the master's words and his anger began to subside.
