Synopsis The author argues that today, as never before, Hinduism is under an invisible multi-dimensional siege; and that the manifestation f this siege can be seen by those alerted to it. The author suggests that the siege against Hinduism today is visible in four dimensions: Religious, in the denigration of Hindu icons; Psychological-e.g. in the foisting of a fraudulent version of our history; Physical-e.g. the Islamic terrorist-driven ethnic cleansing of Hindus in Kashmir and Bangladesh, and the money-induced conversion of Hindus to Christianity; Cultural- e.g. through globalisation of tastes, dress and interpersonal morality that are determined in the Anglo-saxon white Christian world (“The West”). The author argues that Hindus must collectively acquire a new mindset, to meet the growing challenge from a highly multi-dimensional siege which is international in character-otherwise over the coming millennium, Hindus run the risk of perishing like the ancient Greeks, Egyptians or Babylonians.
