Are you afraid of pain?

Now at that time, between Savatthi and the Jeta’s Grove a number of boys were tormenting fish. Then the Lord saw those boys and he went up to them and said: “My boys, are you afraid of pain? Do you dislike pain?” 

“Yes, sir, we do.” 

Then the Lord uttered this verse: 

“If you are afraid of and dislike pain, 

Do no evil either openly or in secret. 

If you are doing or plan to do evil, 

You will not escape from pain 

By running away or fleeing.”

~ Udana 51.
