Before you ask why, you may need to first go first directly to the identity. Who is having this emotion? Or you may need to first ask “what is this?” and don’t settle for the first thing that comes up. The very thing you are trying to avoid, whatever is being ignored that keeps the self-centeredness going, will start to show up. Sit down and be kind to everything by setting all of your senses on just receive. Be extremely generous by giving your attention to whatever arises.
