For it's genre it's very good.
The biography of Hubbard. He was so disturbed.
I didn't know much about Scientology. I knew they believed in aliens or we were aliens or something. After listening to this book I'm actually anxious for the poor people who are in the Sea Org. I really like the line in the book about people joining and being in religions, not because they are evil people but because they want to be better people, help people, help themselves. That's a noble desire, it's sad how people exploit others. I don't understand why anyone would want to be part of this "religion" unless you're Tom Cruise. Everyone else seems to be disposable and unimportant. For Tom Cruise it must be great, your own personal slave team and a religion set up where you can't do wrong. I always kind of thought he was a nutter, but now I think he's beyond narcissistic, maybe even sociopathic.
I am not a person who listens or reads self-help books, or even many books on spirituality or religion. ( Thomas Merton, Richard Rohr, and a few others being the notable exceptions)-- so I approached this warily. I have found though that John O'Donohue's writing describes my experience of Spirit, and his words are expanding my vocabulary for experiences I've had, a way of life I have known, but never managed to express.
I don't imagine his path is one that would speak to all seekers. But if you have been raised with a celtic consciousness, his writing will help to round out your living connection to Spirit and do it in a way that does not conflict with you Christian faith, but rather rounds it out and deepens it.
O'Donahue's voice is clear and musical, with a sort of clear high sound, like the wind working against the ancient stones. It can be a little tiring if you do not listen closely. My suggestion is to take in what he says in short bits. His writing is so full and deep, just like a rich fragrant dish of some delicious food, you don't want to consume it, but rather take it in slowly, and let it work in the hidden parts of your heart, and then go back for more. There is time. There is no need to rush.
Finally I just want to express my profound gratitude for the life and work of this man. He managed to bring together and make sense of the tangle of the celtic consciousness, which is hidden, almost lost in the rush and bright light of modern scientific western thought. -- I am sorry his "clay form" is no longer walking around among us, and yet so grateful that his wisdom has been shared and continues to be heard.
