Don’t think unkind thoughts about anyone. Do this for your own good. Harboring unkind thoughts is not good for you. Not good for your spirit; not good for your body.
Here’s how one reader put it: “Although I have spent much time over many years trying to remove sarcasm from my speech, I was able to see this week how that is a form of unkindness that I bring back upon myself as well as projecting it outward onto others. It has been a most instructive week and the practice continues.”
