I have read 5 SW books now. This one is undoubtedly my favourite. I refer to it regularly and have read it fully cover to cover twice already and only bought it 3 weeks ago. I love it.
I like the way its written. Its like a short instruction manual for the human soul. It sums up everything beautifully with lots of little exercises to help you on your way to discovering your infinite eternity.
If you beleive everything, keep your mind open, and just sit back, practice, and enjoy the experience, you'll be in for a great ride.
