But in the second half of the twelfth century A. D., we find a new type of Muslim saint appearing on the scene and dominating it in subsequent centuries. That was the sufi joined to a silsila. This is not the place to discuss the character of some outstanding sufis (...) The common name which is used for these early sufis as well as for the teeming breed belonging to the latter-day silsilas, has caused no end of confusion. So far as India is concerned, it is difficult to find a sufi whose consciousness harboured even a trace of any spirituality. By and large, the sufis that functioned in this country were the most fanatic and fundamentalist activists of Islamic imperialism, the same as the latter-day Christian missionaries in the context of Spanish and Portuguese imperialism.
