The present book speaks of the importance of water as far as it shapes our culture. Bangladesh as one of the ancient countries represents a kind of culture that is unique in the world. Many of our cultural heritages are getting lost because of urbanization and also for absence of water in our rivers. Again there has been lack of awareness and interest in these things by those who have either poor knowledge or are indifferent to their identity. A nation cannot survive if her citizen is apathetic towards the culture she possesses for generations. Our youth need to be trained to find out their roots and the history of our brave people. Bangladesh is a country where the culture is diversified. Yet never has such diversification affected our culture. An interesting part of the book is the discovery of a kingdom, named Gangaridae that covered almost the whole of Southwest region of Bangladesh. Kotalipara, presently an Upazila under Gopalganj district of Bangladesh, was the capital of Gangaridae.The History of Greece recorded a story that Alexander, the Great feared to invade Bengal because of Gangaridae. The story is given in complete form in the chapters dealing in “Archaeology”. What is more interesting that Bangabandhu Sheikh Mujibur Rahman, the founding father of Bangladesh, was born in Tungipara village under Kotalipara Upazila and the country was liberated from Pakistan under his leadership. It is indeed a strange coincidence.
