One of the problems that we have generally is that when somebody does something to us or violates our principles, we keep picking on that particular thing... For instance, because you have labored through your tonglen practice and have worked so hard, you develop tremendous arrogance. You feel as though you have gone through so much and that your effort makes you a worthy person. So when you meet somebody who has not accomplished what you have, you would like to put them down. This slogan is very simple: don't do that.
