The disciple was always complaining to his master,
“You are hiding the final secret of Zen from me.”
And he would not accept the master’s denials.
One day they were walking in the hills when they heard bird a bird sing.
“Did you hear the bird sing?” asked the Master?
“Yes,” said the disciple.
“Well, now you know that I have hidden nothing from you.”
“Yes.”

Anthony de Mello
