Peasant and the monk

On a hot summer day, a peasant was tending to his crops in his field. From a distance, he noticed an old monk trying to push a wooden boat into the river. First, the boat got stuck in the mud. While trying to push the boat towards the river, the monk noticed that a rock was blocking the boat's way. He had to maneuver the boat around the rock and put wooden sticks under the boat to lift it up, away from the mud. Upon seeing this, the peasant started walking towards the monk to help, but by the time he reached the river, the old monk had already managed to put the boat into the river. The peasant was quite impressed with the old monk's outstanding tenacity and physical duress.

He asked, "I see that you have so much physical strength - it is truly impressive. We, the peasants, were told that monks had supernatural powers. Since you are a monk; can you do the same thing solely by mind power?"

The monk did not respond first, he jumped into the boat and started rowing. Suddenly, he turned towards the peasant and spoke:

"I already did."
