If you have not read the wikipedia page on Chogyam Trungpa Rinpoche you might find it entertaining, enlightening, or even both. Apparently the fellow had some difficulties in the area of practicing what he preached. I have some personal experience with the Boulder Tibetan Buddhists and they are unconventional to say the least. Orthodox Buddhists are not supposed to drink alcohol, eat meat, smoke, or indulge in casual sex.

(I agree that Cutting through Spiritual Materialism has some marvelous content. Like most Buddhist writings it has a low signal-to-noise ratio for me.)
