I just want to echo all the other 5 star reviews for this item -- this brilliant set is ABSOLUTELY ESSENTIAL for anyone who wants to understand what the Course/workbook is really saying. I've studied/practiced the Course off and on for many years, and I've seen first hand how incredibly easy it is to become very new-agey and completely run the wrong way with the Course's teachings. Studying any of Dr. Wapnick's writings is like having the blinders lifted from one's eyes in this regard, and I believe "Journey Through the Workbook" is by far his best and most important work to date. This set has completely transformed by understanding and practice of the Course; I cannot recommend it highly enough.
