This text deserves all the praise heaped on it by one of the reviewers.There is not a wasted word in it. It is thoroughly practical, and rightly so, because (a) based on the teachings of experienced masters and (b) translated by an eminent lay-practicioner. Master Hsu Yun (1840-1959) recommended that Lu KUan Yu (Charles Luk) should present these texts. Be it the Surangama Sutra, Ch'an (Zen,T'ien Tai or Taoism,everything is presented clearly - allowing for the fact that only a practicing reader - will find the meaning between the lines.One reviewer found the 'Taoist' section difficult,but it is based on the teachings of Chao Pi Chen, a famous Taoist, known all over China, before the revolution. The detailed notes on T'ien Tai practice are for the most part drawn from Master Yin Shih Tsu, an eminent practicioner who cured himself of T.B. - using these techniques. This book is a treasury of helpful advice and relevant information.
As a novice, I found this book troublesome. While the information is very interesting for my Buddhist study, it offered me little practical help in my meditation practices. I do enjoy the text for its readings and explanations of the various schools of Buddhist thought. But I have found better texts and more helpful texts when it comes to instruction on personal meditation.
