Inspired by Yamada Roshi’s account of his kensho in the book, “Zen: The Authentic Gate.” Nyogen Roshi encourages us to remember that just as suffering and death are real, enlightenment is also real. “Without enlightenment, there is no Zen Buddhism,” Roshi says. “Yamada wasn’t some mythical character. I met him! He was a remarkable man who demonstrated for us that this can be done.”
