Castes are autonomous, and there is no authority anywhere to compel a caste to admit a new-comer to its social life. Hindu Society being a collection of castes, and each caste being a closed corporation, there is no place for a convert. Thus it is the caste which has prevented the Hindus from expanding and from absorbing other religious communities. So long as Caste remains, Hindu religion cannot be made a missionary religion, and Shudhi will be both a folly and a futility.
