"You can hit my body but you cannot hit my mind."
One day, before summer Kyol Che, Ko Bong visited Tong Do Sa Temple. He stood at the gate and shouted, “Somebody come here and cut my hair, please. I want to become a monk.” Many monks were angered by his arrogant behavior. They grabbed some sticks and went out to beat him. Ko Bong only said, “You can hit my body but you cannot hit my mind. If you can hit my mind, I will become your disciple.” But none of the monks could hit his mind.
Another time, outside Nam Ja Sa Temple, he shouted the same kinds of things, and again all of the monks were very angry and wanted to beat him. Ko Bong again asked if anyone could hit his mind. At the time, Zen Master Hae Bong heard this and came to see Ko Bong. He asked, “How many pounds does your mind weigh?” Ko Bong could not answer, so he cut off all his hair and became a monk.
