its a amazing book. I read it twice for concept understanding. I can say this is a book which talks about ultimate skill of human being which is not given by god to others i.e. Intellect. Intellect is base of Humans & without it Humans is just like other things as animals & Plants. Our Minds work likes a fire in jungle & if We are not able to control it can damage our life. Even I can say our life is a reflection of our decisions & we can take right decision only if we have a good & mature intellect. this is a wonderful & must read book for everyone.
