Starting on the book

I made an intention while in yoga class. I was dedicating my day's practice to the beginning of my novel. And during meditation, I had a flash of how to set up my main character according to the four levels of reality that were described to me by a friend of mine who is initiated into two different esoteric traditions. The realities she described really resonated with me. (I have not yet figured out a definitive origin of these realities. An online search of "the four realities" brings up many articles for further research.)

The physical reality--just the facts, straight description without commentary.
The psychological reality--this is where we turn the facts into story--give them meaning.
The mythic reality--Story told over and over becomes bigger until it is mythic, becomes an archetype.
The essential reality--where all is one. The essential being of a person does not change.

I spent the better part of the morning doing some research on this and archetypes. In asking about my novel/main character I formulated the questions: What is my character has a defining moment as a child and she transforms that moment into a story that she retells throughout her lifetime until it becomes mythic and a guiding force? And what if she finds out later that her story has been wrong? She must take a journey and make a new mythology for herself.

If you read SUMMERS AT BLUE LAKE, you will understand that these same questions could very well describe the protagonist BJ. I hope it will not be too similar a story. What archetypes would I use to describe BJ, and what archetypes will I use to describe this new chaaracter. I also think it will be interesting to see how it will change my writing to consider these layers of reality as I go along.
