I thought of one of those holders stories when I read the first sentence.
----
In any city, in any country, go to any mental institution or halfway house in you can get yourself to. When you reach the front desk, ask to visit someone who calls himself "The Holder of Fundamentalism"
The person behind the desk will resist or try to stop you. They may even deny knowledge of the holder, but you must continue asking until they give.
He will hand you a key and take you to the end of a hallway. You must use the key to open the correct door. If it opens to an old woman, run. Continue running, don't stop, until you pass out. You will not know until you wake up, whether it was far enough. Hope it is, because death will offer no relief.
If the door opens, and an old man is standing there, wait for him to speak. Under no circumstances may you speak first. The man will ask you, "What is the nature of god?" You may answer in any way you wish, but don't remain silent. He will hand you a book containing the knowledge of all gods. You must never open the book, for to do that will implant all the religious beliefs in the universe into your head, causing instant death.
This book is object 476 of 538. They must never be gathered back together again. Never.
