There is plenty of primary literature available in Arabic and Persian regarding the rise, development, and doings of numerous sufi silsilas in India. Some of this literature has been translated into Urdu and English as well. A study of this literature leaves little doubt that sufis were the most fanatic and fundamentalist elements in the Islamic establishment in medieval times. Hindus should go to this literature rather than fall for latter-day Islamic propaganda. The ruin of Hindus and Hinduism in Kashmir in particular, can be safely credited to sufis who functioned there from the early thirteenth century onwards.
