People may shy away from this book because of the implications associated with the word "channel." The word "channel", as it is used here, simple means clearing the mind so as to allow the universe to give the answers you seek. Many would understand this process as a component of meditation.
Regardless of the linguistics, this book is a must read for anybody interested in meditation or channeling. There are many “how to" books, but this is one of the few that will answer all of the questions you have on the subject. This book sets the standard.
