Let's walk on water

A man came to Ramakrishna and said I can walk on water, what can you do? Ramakrishna said, you really can walk on water? How much time did it take for you to learn this art? He said, it took eighteen years.

Ramakrishna started laughing. He said, idiot of idiots! I give two cents to go across the river. You took eighteen years to walk across water? What’s the use? Go and walk on water, keep on walking. You really can walk on water, can’t you? Just give two cents to sit in a boat and you can go across. For this two cent crossing you wasted eighteen years?
