I have come to deal with principles. I have only to preach that God comes again and again, and that He came in India as Krishna, Rama, and Buddha, and that He will come again. It can almost be demonstrated that after each 500 years the world sinks, and a tremendous spiritual wave comes, and on the top of the wave is a Christ.
Swami VivekanandaMy child, what I want is muscles of iron and nerves of steel, inside which dwells a mind of the same material as that of which the thunderbolt is made.
