Seriously. Once you give in to this organic thing, all hell breaks loose. Mysterious elements show up out of seemingly (key word, that) nowhere, characters take on a mind of their own and refuse, refuse, to do what you’ve told them to. The bad guy decides he’s not the bad guy any longer and strange interpersonal dynamics and heretofore unsuspected relationships that you have given no conscious thought to, begin appearing on the page.

The thing is, this is one of the reasons people give for not wanting to outline--a fear of stifling just this phenomenon, and I totally get that; that's their process and choice. For me though, I don't know how to get moving on the page without some sort of outline or plot and it is only when I am actively moving on the page that these sorts of spontaneous things begin happening.
I read somewhere, and I can't for the life of me remember where (Katy, you might know the source of this idea) that the reason music became part of religious ritual was because the monks believed it created a space through which the Divine could enter.
Maybe for some of us outlines are like that. Creating an outline is like playing the music that will allow the Creative Spark to ignite...
