Ever wonder why it seems like you have a devil on one shoulder whispering in your ear and an angel on the other speaking the opposite? Why do we make bad decisions even when we know they're bad? Understanding a simplified version of two parts of the brain helps explain this.
There are several phrases I've heard used to describe these two parts: CHILD verses ADULT brain, GO verses STOP brain, and PRIMAL verses RATIONAL brain.
The image above breaks it down very simply. The primal (fight or flight) part of our brain seeks to avoid unpleasant feelings. Calling it the 'child' brain is accurate because it does not consider consequences of actions - it can't because it has no concept of time.
Feel thirsty? Find water. Feel horny? Find sex. Feel afraid? Find safety. Feel depressed? Find comfort.
In contrast, our rational brain is the limiter. Rational brain says don't drink water from a gutter, don't have sex with just anyone, don't run over your friend to get to safety, and don't do drugs because they may cause more harm than good. Our 'adult' brain has the capacity to predict and assess risk. Ideally, the two parts of our brain work together to identify and fulfill needs with a healthy amount of risk assessment.
The problem for someone who has been addicted to drugs or alcohol, is that the "GO" part of the brain has been running the show, and it's difficult to override established habits for new ones, especially because it requires delayed gratification. You know about this challenge if you've ever tried to diet. Your 'shoulder devil' isn't trying to hurt you, it just wants you to avoid discomfort and tells you, "go ahead, have cake." In the words of Gollum from Lord of the Rings, "We wants it, we needs it." Opposite, your 'shoulder angel' is telling you to fight the good fight.
Hopefully understanding why you have these internal mind battles will help you ultimately win the war of good verses evil. The choices are yours to make.
