But have you ever thought as to how the efforts toward the abolition of castes can be made successful? Castes cannot be abolished by inter-caste dinners or stray instances of inter-caste marriages. Caste is a state of mind. It is a disease of the mind. The teachings of the Hindu religion are the root cause of this disease. We practise casteism, we observe untouchability, because we are asked to do it by the Hindu religion in which we live. A bitter thing can be made sweet. The taste of anything can be changed. But poison cannot be made Amrit [=nectar]. To talk of annihilating castes is like talking of changing poison into Amrit. In short, so long as we remain in a religion which teaches man to treat man as a leper, the sense of discrimination on account of caste, which is deeply rooted in our minds, cannot go. For annihilating castes and untouchability from among the Untouchables, change of religion is the only antidote.
