Recently I was studying Swami Vivekananda's speech in Chicago. This one is to those who create variance in people name of casts and religion. This story from Vivekananda for them :- I should tell you a story which would illustrate the cause of this variance. A frog lived in a well. It had lived there for a long time. It was born there and brought up there, and yet was a little, small frog. Of course the evolutionists were not there then to tell us whether the frog lost its eyes or not, but, for our story's sake, we must take it for granted that it had its eyes, and that it every day cleansed the water of all the worms and bacilli that lived in it with an energy that would do credit to our modern bacteriologists. In this way it went on and became a little sleek and fat. Well, one day another frog that lived in the sea came and fell into the well. "Where are you from?" "I am from the sea." "The sea! How big is that? Is it as big as my well?&
