I'm reviewing the CD rather than the book, and I assume the contents are the same. It says 'unabridged' on it, anyhow.
I agree with the three previous reviewers in saying that this is a little cracker of a book/CD. It's not my first encounter with the key ideas of Advaita, and I'm not sure how it would have struck me if it had been. I think I would have been more wowed than baffled.
It does challenge, and that's one of its strengths. Another is that it goes with one good central metaphor (I'll not say which, though the title gives a fair clue) and that metaphor works for everything he is saying, without seeming to break down or mislead. And in case you're wondering whether the exercise is merely cerebral, I felt more gripped emotionally by the end of it than I am by Hollywood's best.
