Lecture at Westminster Abbey (1873); as quoted in Hinduism : A Religion to Live By (1997) by Nirad C. Chaudhari <!-- Oxford University Press February pp. 116 -117 -->
Context: The worship of Shiva, Vishnu, and other popular deities was of the same and in many cases of a more degraded and savage character than the worship of Jupiter, Apollo or Minerva.... A religion may linger on for a long time, it may be accepted by large masses of the people, because it is there, and there is nothing better. But when a religion has ceased to produce defenders of the faith, prophets, champions, martyrs, it has ceased to live, in the true sense of the word; and in that sense the old orthodox Brahmanism has ceased to live for more than a thousand years.
