There may be castes among Sikhs and Mohammedans but the Sikhs and the Mohammedans will not outcast a Sikh or a Mohammedan if he broke his caste. Indeed, the very idea of excommunication is foreign to the Sikhs and the Mohammedans. But with the Hindus the case is entirely different. He is sure to be outcasted if he broke caste.
