Swami Vivekananda's Parable of the Frog

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... 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?" and he took a leap from one side of the well to the other.
"My friend," said the frog of the sea, "how do you compare the sea with your little well?"
Then the frog took another leap and asked, "Is your sea so big?"
"What nonsense you speak, to compare the sea with your well!"
"Well, then," said the frog of the well, "nothing can be bigger than my well; there can be nothing bigger than this; this fellow is a liar, so turn him out."

That has been the difficulty all the while.

I am a Hindu. I am sitting in my own little well and thinking that the whole world is my little well. The Christian sits in his little well and thinks the whole world is his well. The Mohammedan sits in his little well and thinks that is the whole world. l have to thank you of America for the great attempt you are making to break down the barriers of this little world of ours, and hope that, in the future, the Lord will help you to accomplish your purpose.
