Zen

"Whenever you want to do a bodily action, you should reflect on it: ‘This bodily action I want to do—would it lead to self-affliction, to the affliction of others, or to both? Would it be an unskillful bodily action, with painful consequences, painful results?’ If, on
reflection, you know that it would lead to self-affliction, to the affliction of others, or to both; it would be an unskillful bodily action with painful consequences, painful results, then any bodily action of that sort is absolutely unfit for you to do. But if on reflection you know that it would not cause affliction... it would be a skillful bodily action with pleasant consequences, pleasant results, then any bodily action of that sort is fit for you to do."

The Buddha
