You can read this book starting with any chapter. But chapter 8 is about letting go and that's where the action is. My favorite is chapter 4, Educating your Baggage. That was fun to write and I'm an expert on baggage. You might not want to jump ahead without reading chapter 4 and 10 those are about fighting and the false self. You probably need to have those under your belt before tackling 8. There are many books out there about enlightenment. But as far as I know there are none for engineers.
