Another reviewer harshly criticized Chogyam Trungpa's lack of compassion with respect to the meditation practices and the non-dualism that they promote. While I would concur that the Rinpoche's style is very straightforward, I do not believe that is the result of a lack of compassion or any extra "harshness" on the his part.
His writings are direct, and concise. I find that his writing style very much belies his primary language and the translation is almost exact, phrase-for-phrase. This often leads to difficult reading because the subject-verb-object relationships and sentence structures do not map well between Tibetan and English. Additionally, he spends much time discussing the failures of language with respect to non-dualism. The use of any language to describe concepts inherently opposed by language leads to several tricky sections where I was forced to rigorousely parse each section in order to understand his point. The rewards of better understanding and a much diminished ego were well worth the effort.
All in all, this book is an excellent building block that doesn't treat meditation in the same feel-good, "New Age" style of so many other authors. It is definately built upon the underlying structures of Kagyu-style Buddhism. If Trungpa hurts your ego and makes "you" feel virtually non-existant... Well that's kind of the point of non-dualism in the first place.
Chogyam Trungpa Rinpoche does not engage in "idiot compassion." This book will not gratify any of the desires of your ego. Instead it has (as the foreward says) an "iron hook" of compassion, which will attempt to cut away your ego & expose you to the hard lonely reality of practice.
In his first exposition of the nature of meditation Rinpoche tells us to sit without pretensions, "like a disused coffee cup." He describes the feeling of spaciousness that comes from abandoning the ego as a reference point as "boring" & "suffocating." He does not give us any room to use meditation as an ego toy.
I recommend this book highly to anyone who is seriously interested in the hard, confusing road of spirituality. After many years of meditation, feeling very confident & special, reading "The Path is the Goal" and "Cutting Through Spiritual Materialism" was a kick to the gut.
When you're done having fun pretending to meditate, come to "The Path is the Goal" & be cut open by Chogyam Trungpa's absolute unwavering compassion.
