Is creativity divine or a ghost?

I love TED (Technology, Entertainment, Design) - a conference, site and a meeting place for creativity, knowledge and great ideas in California. Not to long ago author Elisabeth Gilbert - who wrote the mega hit Eat, Love, Pray - spoke about how to nurture creativity. I watch this for the free thinking, the laughs and because it gives me relief when I struggle with my own writing. Looking forward to read her follow up Commited, that I got for Christmas.
