The thing about having to practice over time to attain spiritual awakening makes it hard for me to say whether I will really get it from what the Dalai Lama sets forth here. I get some of his reasoning on an intellectual level, but I haven't become enlightened yet.
I did particularly enjoy reading this book. I will pick up this book from time to time to review the reasoning/mindful approach he sets forth. Who knows if I will ever get anything out of it. From what I've read of the Zen schools, I shouldn't have that expectation.
