creative force...

"What about the creative state? In it a man is taken out of himself. He lets it down as it were a bucket into his subconscious, and draws up something which is normally beyond his reach. He mixes this thing with his normal experiences, and out of the mixture he makes a work of art... And when the process is over, when the picture or symphony or lyric or novel (or whatever it is) is complete, the artist, looking back on it, will wonder how on earth he did it. And indeed, he did not do it on earth."

- E.M. Forester, The Raison d'Etre of Criticism in the Arts
