About the book: 2014 / Xu-yun (1840–1959) - the most famous enlightened teacher of the Chan tradition of the 20th century. in China. He achieved enlightenment without the help of teachers and revived decaying teachings solely through the power of his own insight, becoming something of a living legend of his time. His life and example evoke the same feelings of awe and inspiration in the minds of Chinese Buddhists that Tibetan Buddhists feel for Milarepa. The book contains the autobiography of Xu-yun and his teachings. The first edition of the book was published in 1996 under the title “Empty Cloud.” This revised and expanded edition, verified with the original in Chinese, includes new materials, including the instructions of Xu-yun at the second Chan seven-day period.
