The Chan School of Chinese Buddhism emphasized not relying on words and language, and yet its patriarchs and lineage masters were forever creating what seems like a tangled vine of words. How to explain this seeming contradiction? Since 1976, Master Sheng Yen has been teaching Chan, talking about Chan, and writing about Chan all over the world. Although he has read through the history and records of Chan collected in the Tripitaka, his focus is never to gain more knowledge about the Chan School, or to investigate the factual accuracy or authenticity of Chan Buddhist studies, much less to analyze and figure out what else the ancient worthies left behind and what that meant. "My main objective is to use simple, common language to share the concepts and meditation methods of orthodox, doctrinally correct Chan practice with the contemporary world." said MasterSheng Yen. The author of the book, Chan master Sheng-Yen (1930-2009) has published many important books on Chan which mostly collected from the lectures he gave during his life time. This book collects 16 lecture records on Chan practice and theory given by Master Sheng Yen, which are not possible to be given repeatedly. During his long career as a monk, teacher of Buddadharma, and founder of monasteries, meditation centers, and educational institutions, Master Sheng Yen was also a very prolific lecturer, scholar, and author. Over the years, his published works in many languages have benefited students and seekers of the Dharma all over the world.
