Integrity is a state of being whole. But what does it mean to have integrity within your own mind, within your own thought process?  We tend to believe that every thought we have we must believe. But that is just not true. Our brains will always come to judgments and conclusions; they will come up with things to say to us all the time, things that are threatening and fearful. This is what the brain is meant to do. We tend to be very critical of our thoughts, we think "if I am thinking this, and I am scared of this, then it must be true." Our brains are always looking for threats; relationship threats or social belonging threats. Your brain will create a story, a fear story of what could go wrong and how it will go wrong. And we have a physiological reaction to these stories if we spend a lot of time thinking about them.  That is how powerful our thoughts really are. And they don't always represent our true self.
