The realm of the story is a metaphor of the Self.
For me, The Self is everything that you could be. It is the balance of all that is good in you and all that is bad in you, it is the struggle to decide upon and master that perfect balance, it is everything that you strive for and everything that you fail to be, and it is in constant flux. It is defined by the constant struggle between two forces – the forces of conscious and subconscious, forces of light and dark – The Ego and The Shadow. The champion of the conscious forces is The Ego and the story of Harry Potter illustrates this perfectly.
Harry is a hero in his story and the Hero is always a metaphor for The Ego. Like your Self, Harry’s world consists of two halves – in his case this is the Muggle world and the Magic world. He grew up in a somewhat restricting Muggle world, his conscious world, but if he stayed there and ignored the magic world, his subconscious world, he would have bumbled along doing whatever he did and not be any the wiser, but he didn’t; he delved into the magic world heart and soul and learned all sorts of new and wonderful things and had great experiences as magic became more and more a part of his conscious life. His Ego was all the better and all the stronger for this delving as its experience of the world was enriched. But he had to be careful how deep he delved for there was a threat to his stability. If Harry is the Ego then Voldemort is the metaphor for the opposing force – the dark to The Ego’s light. Jung called this The Shadow. The Shadow is everything that The Ego is not. If life demands something from you that The Ego does not have then the Shadow has it and The Ego must retrieve it and if the The Ego has something that life does not require, The Shadow will swallow it. That is why the stronger that Harry gets the stronger Lord Voldemort gets and that is why their destinies and deaths are intertwined.
The Self is defined by the battle between these two halves, but there can never be a winner – In the mind there is no death, there is just change – what dies in The Ego is swallowed by The Shadow and vice versa, and change can only be brought about by the ongoing symbiotic exchange between them.
But it needn’t be a battle, with hypnosis we can focus on certain changes quickly and efficiently so they do not get caught up in the constant battle inside your mind.
