The mind only knows it's own point of view. It never goes outside of itself. Unaware of how our present is contaminated by our past, this point of view goes unchallenged and the mind considers it to be completely true . Human beings who are unaware of this tend to live their lives believing that they are victims of circumstance. Constantly trying to change those circumstances. They are not aware that they are creating these experiences. They use the same thought process to attempt to change them as they use to create them. They think that because they thought something it must be true. They are stuck in a reality that they have created. A reality that works perfectly well to the belief they hold, but a reality doesn't work for them in life.
