Caste System, for nearly two millennia, has been an inseparable but at the same time a well-integrated part of the Hindu culture, nay Indian culture. Started as an institution of the Hindus, it engulfed other faiths too which stand for a homogeneous society. Thought professedly developed as a system for division of labor, it eventually ended as a mechanism for creating birth-centric divisions among people. it is a wonder that the boundaries erected for castes have not been erased even after two thousand years. Any attempt to demolish the caste system has very often met with hostile reactions. This book brings out the nitty-gritty of caste system apart from tracing the origin and growth of caste. Since ages India has been a cauldron of human races and the book attempts to find the relevance of racial differences in the formation of caste with a study of the Vedas. A discussion on the Surdas includes a discussion on slavery. Certain age-old-drilled-in dogmas that holy books do not approve of caste system have been taken up for an objective discussion.
