Layer 4 is one of the more difficult to learn about. Why? Because despite the fact that we all have this layer in us, even normal people have trouble loving this part of themselves.
What does Layer 4 contain?
Everything which involves urges to punish someone, anything from wanting to momentarily kill your kids, to wanting to punish your neighbor for cutting your rose bushes down.
This stuff even includes wanting to kill the president for his lack of decisions to wanting to fire the coach of your favorite team.
And then there is the more personal stuff, wanting to punish yourself for your mistakes or for seemingly causing hurt to others like to your children. In fact, many people actually do punish themselves for their children's wounds.
All these urges, whether just experiential or also behavioral, fall into the content of Layer 3; "uncivilized blame."
