The ZM asked him why he was so angry. The student said, "I've been here for two years and you've never in all that time revealed to me the secret truth." The teacher feigned astonishment and said, "How can you say that? When you called my name, didn't I answer? When it was time to wash the dishes, didn't I hand you the dishrag? And when you bowed to me, didn't I return your bow?" Upon hearing these words the student had a significant enlightenment experience. The truth is so obvious that it is constantly overlooked.
