This compilation of Buddhist biographies, teaching and transmission stories of Indian and Chinese Chan (Japanese 'Zen') masters from antiquity up to about the year 1008 CE is the first mature fruit of an already thousand year-long spiritual marriage between two great world cultures with quite different ways of viewing the world. The fertilisation of Chinese spirituality by Indian Buddhism fructified the whole of Asian culture. The message of this work, that Chan practice can enable a free participation in life's open-ended play, seems as necessary to our own time as it was to the restless times of 11th century Song China. This is the fourth volume of a full translation of this work in thirty books.
