“As soon as there’s anything unskillful in your thoughts, words, and deeds, remove it. Don’t let it hang around for a long time. It’s like a wound appearing in your body, or a thorn sticking into your foot. You want to remove it, but would it be better to remove it today or tomorrow? Or how about taking it out next week?
Or suppose you get a stomachache today. A stomachache is painful, and you want the pain to go away. But do you want it to go away today, or would tomorrow be better? Or would you rather wait for a week for it to go away?”
