Drive all blames into one.

This is advice on how to work with your fellow beings. Everyone is looking for someone to blame and therefore aggression and neurosis keep expanding. Instead, pause and look at what’s happening with you. When you hold on so tightly to your view of what they did, you get hooked. Your own self-righteousness causes you to get all worked up and to suffer. So work on cooling that reactivity rather than escalating it.
