Despite being a small book, which I'm sure can be read in one sitting, this is a deeply contemplative and philosophical gem. You will want to read this book over and over again, it's depths will take you to the depths of your own self. Since reading this book I have begun to meditate, with awareness, in most aspects of my life - work, socialising and rest. I have never been so conscious of my breath and the breath of the universe that breathes within me.
Enjoy, accept your being.
