I just completed a book called The Magic Mushroom: Key to the Door of Eternity. It’s about magic mushrooms, sure, but more about one man’s quest to pursue the ability to enhance ESP in people. Lots of good stuff in there - stuff I’d been told about as a kid.
But what has me posting here is the fact that this man was approached by the government on various occasions regarding answers to the quest. And then this guy comes along who has unprovoked trances in which Thoth and the ancient Ra Ho Tep announce they want to talk about mushrooms, and then go through the motions of revealing not only what they do but the proper Egyptian ceremony on how to do it.
Then when the information was out, the two entities lost their grip on the psychic and went away. (To the psychic’s relief.)
I’m amused by this, personally. But I’m wondering if anyone else has read the book.
