Nobody is born angry, judgmental, bitter, jealous, fearful, stressful, insecure, unhappy, doubtful, self-conscious, covetous, mean or racist. These are things that are taught to us at a young age by adults who have those traits.
Peace comes when we shed these negative layers and get back to who we were when we were born – happy and loving. Then we have peace within ourselves and peace in the world.
