He said, when he heard that the southern School of Chan was flourishing, he railed against it saying, those who leave home these become monks, those who leave home may study the great meaning of the Dharma for 1000 kalpas and spend a further 10,000 Calpis, performing detailed Buddhist practice, yet they still won't become a Buddha. How dare those southern devils say that just by pointing at the human mind, we can see our self nature and attain Buddhahood and to go drag them from their caves, and exterminate their ilk, and thus repay the kindness of Buddha. He was on a mission. So he set off with all of his commentaries his favorite commentaries on the Diamond Sutra, and went on a long journey to go down there and get rid of them. And then he had this famous encounter with the old woman on the road, who was selling them some. And she posed this question that that completely flipped them out. She said. He told her that he was he was a great scholar in the Diamond Sutra. And she said, I have a question for you. If you answer it right, then I'll donate a dim sum to you if you can't answer, then you must go elsewhere. Now, my question in the Diamond Sutra, it says, past the mind cannot be attained, present mind cannot be attained, future mind cannot be attained. And she said, I want to know Mark, what mind are you revealing right now. And at that he was left speechless. And then he went on to Longton, another famous master there. He had this, he had a long discussion in deep into the night about the Diamond Sutra or really the essence of the Diamond Sutra form and emptiness. And then, as he was leaving, he asked for a candle so he could find his way out into the dark. And Luke tan lit the candle, and as he handed it to toxin, he blew it out. Darkness and that that took son came to enlightenment. And it was a complete conversion for him. Then, then, you know so many people who went from one extreme to the other, he had no use anymore for sutras, scriptures of any kind doctrine. He went out, placed all of his Diamond Sutra material in a pile in front of the Dharma Hall, and lifting a candle. He said, All the mysterious doctrines are but a speck of dust in a vast void. All the great affairs of the world are but a drop of water, cast into a boundless chasm. And then he set fire to all those books that he had cherished so much.
