當一位弟子正在靜坐祈禱，大師拿着一塊磚，死勁地在地上磨。
起初，這位弟子把它當作考驗自己專心的試煉，而欣慰地接受。然而，噪音愈來愈尖銳，他終於耐不住性子，大吼：「老天，你究竟在幹什麼？難道你沒看見我正在祈禱靜坐嗎？」
大師靜靜地說：「我想把這塊磚磨成一面鏡子。」
「你瘋了！磚裏怎能磨得出鏡子來？」
「彼此彼此，在自我內心又怎能生出真正的靜觀者？」
ABSURDITY
The Master kept scraping a brick against the floor of the room where his disciple sat in
meditation.
At first the disciple was content, taking this to be a test of his powers of concentration.
But when the sound became unbearable he burst out, “What on earth are you doing?
Can’t you see I am in meditation?”
“I’m polishing this brick to make a mirror out of it,” said the Master.
“You’re crazy! How can you make a mirror out of a brick?”
“No crazier than you! How can you make a mediator out of the self?”
