From: Warrior's Solution 4
One day a man reproached Bayazid, the great mystic of the ninth century, saying that he had fasted and prayed and so on for thirty years, and not found the joy or peace which Bayazid had prescribed. Bayazid said that he might continue for three hundred years and still not find it.
"Because your vanity is a barrier to you"
"Tell me the remedy."
"The remedy is one which you cannot take."
"Tell me nevertheless."
Bayazid said, "You must go to the barber and have your very respectable beard shaved, remove all your clothes and put on a simple girdle, fill a nose bag with walnuts and suspend it from your neck, go to the market place and call out, 'I will give a walnut to any boy who will strike me on the back of my neck.' Then continue on to the courthouse so that they may see you."
"But I cannot do that. Please tell me something else that would do."
"This is the first move and the only one," said Bayazid, "but I had already told you that you would not do it, so you cannot be cured."
