Master is sitting outside steps of temple watching his number one pupil meditating in the courtyard and quietly enjoying smoking his pipe.
Suddenly pupil opens eyes and exclaims. Master, Master, I have it, I have it. I know the answer to everything.
You do? Asked Master, and what is it?
Everything is just an illusion Master, all is just illusion.
Master gets up and approaches student while
Pulling hard in his pipe and as he was passing student, turns the contents of his red hot pipe out on top of the nice bald head and bang the pipe down hard to empty it well showering students bald head with burning embers.
Student jumps up, shouting, Master, what are you trying to do. I'm burning all over. Are you trying to kill me. What's the matter with you??
Ahhhh.. Illusion make you very angry.
