It's a bad idea to discount anything as impossible, even if it seems to contradict out present understanding of the universe. So here's what I suggest: we lock him in a room with windows/cameras so that we can observe him. He may have a bed and whatever meditative tools he needs, but absolutely no food or water. If he survives for a full month, he's for real and I'll follow whatever he has to teach. If not, we should parade his corpse around, along with a news report along the lines of "being retarded kills"
...yeah, I'd say he's either batshit fucking loco, or really attention starved.
