I believe humans don't have the freewill they think they do.I believe like all other animals instincts we make choices out of fear and faith. When a deer feels safe and full of faith it can think along the lines of finding green grass to eat and shade to lay in and such. Once it senses danger its line of thinking will change. It will seek out the danger, decide what direction to dart of etc.. Too much fear and maybe freeze. Humans are the same way.
the biggest mistake humans make is they try to use their thinking to control their emotions. We don't realize that in order to be happy, feel safe and full of faith all we have to do is release the fear or emotions.As we release the emotions our line of thinking actually changes like the deer in the field.People hold on so tight to emotions and refuse to release them and it causes the brain to be stuck in a certain mode of thinking.My personal belief is that eventually when you hold on to bad emotions long enough without releasing them they cause the mind to be stuck in a certain unhealthy pattern of thinking that eventually alters the chemicals causing chemical imbalances(mental illness) Even good emotions can cloud up the mind and clarity of thought.Releasing good emotions also has a great benefit to clearing the mind and so you can make better choices and keep bringing yourself up to a better state of thinking and feeling.The only way to feel good is to allow your self to feel and release the bad feelings no matter how bad they feel and don't allow them to dictate your thoughts or choices.(sometimes you just have to buckle the seatbelt and hang on) So I guess what i am saying is that are emotional state of fear and faith we are in actually dictates our line of thinking and how we make choices just like the deer.
So in order to summarize this I believe we are still dictated by faith and fear instincts that actually alter our thought processes depending upon which state we are in.If you want to think more clear and positive and make better choices, all you do is release the negative emotions and you climb to a positive state(state you were born and meant to be in ) automatically and your thinking changes automatically.(just like the deer).
