Zafurnamah was a rebuking letter written by Guru Gobind Singh to emperor Aurangzeb. The letter brings out the character of Mughal emperor's officials for writing a false oath on a copy of Qu'ran to ensnare Guru's men. At the same time it makes the emperor aware of his cowardice killing Guru's innocent mother and two young children in the custody of his officials, upon their refusal to accept Islam.
The book discusses how certain events in World history lead to immense suffering of humanity all over the World time after time. It brings out the central reason why certain people and nations encouraged by their religious philosophies invade foreign lands and cause destruction of existing cultures and civilizations to acquire land and wealth at the cost of human life.
The book highlights invasion of Mongols as Mughals and Europeans invading all continents under the famed directive "Doctrine of discovery", resulting in three quarters of the world population by design living in the grip of long term poverty when Europe and North America was developing at a neck breaking speed for two centuries, leading to the creation of a third World.
It makes the reader realize that the letter "Zafurnamah" is neither religious nor politically motivated, but a lesson to the humanity that if humanity is motivated to act by will of a Supreme Being then all world religions as made by man inflict pain and suffering to harm each other and invade other territories intentionally to demonstrate power of wealth and intelligence to deceive humanity continuously.
The book is a chapter from Sikh history and development of people of Bhaaratvarsh seen today as a result of one thousand year of invasions, not Sikhism or their religion.
