The fact remains, this technique--however weird or unreliable--is still one of the best methods for crossing from fiction to non-fiction and back again. Robert Anton Wilson, using his own work as subject material, made some great fiction arise from nonfiction. I wouldn't trust sources that did this to older texts, because that synchronicity is going to be severely diluted by the
translation. Don't ever underestimate the powers of translation--it was translation, and little more, that produced the entire regime of the Holy Mother Church.
