This book introduced a concept of a person being “in-the-box” and “out-of-the-box”.
You usually go into a box when you did not honour something, and have a self-betrayal/deception feelings towards others.
You will start to be defensive, and find faults in others in order to excuse yourself. You will become self-centered and treat others as objects, instead of human beings.
So, be out of the box as much of the time.
This book is very well written and delivers this important concept via a smooth flowing fictional story. A good-to-have on a bookshelf.
Reminder to self: read it again when you are constantly in-the-box
