"The Beastie always lies." This is one of the main concepts taught in the first technique in this workbook. We tend to believe that our thoughts and feelings are true, and it is often quite profound when someone with depression or anxiety realizes that their thoughts and feelings are actually lying to them. The Beastie, which is what Dr. Moore calls the overactive parts of the brain that cause the automatic negative thinking of depression and anxiety, is formed by trauma and/or constant, repetitive negative thoughts and feelings.
