I'm turning first to great collection of biographical material on the Masters, and it's called Zen's Chinese heritage, the Masters in their teachings. And I think these are mostly Tang Dynasty masters. But near the end of the book, we find Dawei just keep it relatively brief, because it can get kind of complicated. But yes, it was born a little years as dates are 1088 to 1163 is a disciple of the Great Yuanwu. Yuanwu is credited as the editor of the blue Cliff records, the great, great collection of koans, the blue Cliff records, and for interesting to hear that both Dawei and his teacher Yuanwu really advanced the cause of women teachers. You know, we take this, I think, pretty much for granted. In our in our contemporary world that of course, there will be women teachers as well as men, but in in Tang Dynasty, and even Song Dynasty, China, you're still beset with his cultural prejudices. And most most women, however, enlightened they were didn't be received Dharma transmission. And that really changed with Dawei and his own teacher great credit to their their free thinking their their spirit of liberty, that they wouldn't be bound by old Chinese ancient Chinese cultural prejudices. You might well ask, wait a minute. What about those other earlier Chinese masters? If they're Zen masters? Why were they caught in that those prejudices? And I don't have an answer for you, except that conditioning can run deep, especially if you're reared in the culture of certain conditioning. That's not much of an explanation, but I think it's the best we can do. It's unfortunately so first Dawei before getting to Yuanwu, he found some other master out I'm not going to clutter this up with a lot of different names. But it says here that the master recognize doorways unusual ability, and assigned him to work as his personal attendant. This has always been considered, especially in China and Japan. Korea is a great honor to work as the personal attendant of a teacher. But it says doorways obstinate personality, clashed with his teacher, leading to an exchange in which the teacher ridiculed young Dawei and he's saying you haven't experienced enlightenment. And the problem is your intellectual understanding.
