Over the past two years I've read many books on how the human mind works and ways to live including many of Thich Nhat Hanh's. While most of Hanh's work I've read emphasizes changing daily life through cultivating the mind, Beyond The Self describes a complete overhaul of our world view on the most basic levels. The text is based on Buddha's ideas of The Middle Way, but leaves out most of Buddhism as a practice. The ideas offered draw many parallels with Jiddu Krishnamurti's excellent Freedom from the Known.
This book is an excellent resource for those who are open and ready to completely redefine their world view and more importantly, removing wrong views. The book is very small, short, and concise. It is very much worth re-reading. Beyond the self is very challenging and had I read it at many less open points in my life, I would have easily dismissed it. I appreciate Beyond the Self's brevity and focus, but for those seeking a more detailed look at Hanh's thoughts on all aspects of Buddhism, I'd suggest The Heart of the Buddha's Teaching. If you are not sure if you are ready for this or are looking for something lighter from Hanh, I would also recommend The Miracle of Mindfulness and Peace Is Every Step: The Path of Mindfulness in Everyday Life.
