It took me a long time to realise that the prison I was in, was the prison of my own mind. My mind had created a version of reality which was far removed from the version of reality that I chose to experience. The way I saw the world was not through the eyes of choice and freedom rather through limitation and restriction.
When I came to realise that I had the opportunity to create my reality by a simple change into pattern, it set me free and on course for a more fulfilling life.
Simply put, when I realised I had the choice of the thoughts that I chose those to think, it made me realise that it changed the feelings that I was able to feel and that changed the way that I saw and reacted to the world. This to me was true freedom.
