there are at least four koans that somewhat span the life of dushaan They start with the first one is in the Mumonkan where it's called Wu Tang blows out a candle. And I'll try to stick to the Chinese dish on because it's not that difficult to pronounce this is not as bad as some others. So dushaan had earned a reputation as being the leading scholar in the Diamond Sutra. This is before he got into Chan. And also the vinyasa school. So both the precepts and the sutras and would go around everywhere today we'd say he's going on lecture tours, lecturing on on the Diamond Sutra, he came to be known as diamond shell. And he heard about this new school, the Zen school, the Chan School, and now they just said, emphasized direct experience outside words outside the sutras and infuriated him. And he has a very strong bumptious carousing character. So He put all his His books, His copies and commentaries of the Diamond Sutra and set off. He said, to exterminate the lot of them, all these Chun practitioners, and then he met this woman, so a woman on the road, who set them back, she offered him a challenge, and he was tongue tied. I'm going through these fat quickly, so you don't have time to go through them in detail. And I left him completely deflated, and open, open to what what more lie hidden what he's been missing, what has been deficient in his Buddhist training and, and it was the direct facing the wall. And then he arrived at the monastery of this new town. And they talked deep into the night and Newton finally said, It's time for you to leave. And he headed for the the door of the heart and saw that it was dark out and he turned and said it's it's dark outside and return, lit a candle held it out. And as the shine was about to take it, Newtown blew it out. And that dude Deshawn came to enlightenment. Next koan fair, featuring dushaan. And now he comes in he arrives at the monastery of Ihsan. Another of the great big names as Chinese name was question. And what he does is he storms into the Buddha Hall where a sign is sitting Zen, he storms in there, he stalks from one side of the hall to the other, and it says nothing, nothing. Then he heads for the exit, and then has second thoughts and he comes back and he goes through the more the proper comportment for a monk. He takes out his bowing cloth, and he says, Master, the sun reaches for his whisk. It's one of these implements that these Chinese masters had. whisked away the flies I guess. He reached for his whisk, and dushaan yells rice, and strides out. So this second koan is fresh, he's fresh off his experience, his deep awakening with routan with the blowing out of the candle. So he's still got all this piss and vinegar in him is arrogance. They have a saying in Japan they heard from Roshi saying that someone after an initial
