The Power of Myth by Joseph Campbell

To a certain extent, you become the carrier of something that is given to you from what have been called the Muses—or, in biblical language, "God." This is no fancy, it is a fact. Since the inspiration comes from the unconscious, and since the unconscious minds of the people of any single small society have much in common, what the shaman or seer brings forth is something that is waiting to be brought forth in everyone. So when one hears the seer's story, one responds, "Aha! This is my story. This is something that I had always wanted to say but wasn't able to say." There has to be a dialogue, an interaction between the seer and the community. The seer who sees things that people in the community don't want to hear is just ineffective.
