Most people, including Hindus, have never looked into what Hinduism really is. If you ask people about Hinduism, most Westerners will have quick answers about its polytheism, idolatry or castism, but if you ask them about the Upanishads or the Gita, about Atman and Brahman, they will have little to say. Most Western textbooks define Hinduism as a conglomeration, an ethnic religion, a castist creed, or a worship of many gods. Such people need to read Sri Ram Swarup to really know what they are dealing with in what is called Hinduism. He will not let them get away with such a sloppy and superficial approach to what is perhaps humanity’s oldest heritage of spiritual knowledge.
