"The present life is the only opportunity that will be given me for helping others in this world. That is a privilege which even Angels are not allowed. We shall have Heaven for ever, but we have only a short time for service here, and therefore must not waste the one opportunity."
- Sadhu Sundar Singh (1889-1929)
Despite his Sikh name ["Singh" is a common last name for Sikhs, as it means "lion", which is the symbol of the faith and the name of its founding philosopher], Sundar Singh was a Christian who served as a missionary to Hindus and others. He disappeared in 1929, no remains were ever found, and some of his more strident contemporary followers think that he lives still.
