Description from the publisher : In this book the importance of unity has emphasized. To the author unity is the greatest power. He says that we have to pay no material price for being united. However, in order to bring unity into existence each one of us must pay some price and that is the price of one’s ego. Ego or the feeling of greatness is the greatest obstacle in the path of unity. Only then unity can exist in a society when its members are prepared to pay this psychological price. Without paying this price no efforts would be of any avail.
