The Satanic Bible. After purchasing it I couldn't say that I was enlightened, because to say that would mean that he produced something that I had never thought or felt (which he did, just wait a second). I instead IDENTIFIED with this so much so, that I will ASAP (in these awful financial times *thanks bush*) apply for my crimson card. I had once studied this from a distance for the longest of times, and never purchased the books, but upon finding it at a Barnes n' Noble it was as if it "called" to me. I purchased it, and it was exactly the "revelation" in which it described.
You stay classy,Satans!
