In the past centuries, Western scholars who studied the complexities of Indian thought had at least two motivations. First, there was a need to understand the alien mind-set which they were eager to ameloriate (convert), for they worked on the conviction that they were bringing truth, light, and salvation to a misguided lot. They felt that it was their evangelical responsibility to redeem lost souls. Some of them, whether overtly or subtly, wanted to give moral ammunition to the colonial governments which were summarily imposing Western values and worldview on the subject peoples.
