It caught my interest when I noticed that psychedelic mushrooms love rye, since ergot, which is another fungi that grows on rye plants and already induces hallucinations (and also death) when consumed, makes the precursor to LSD. Grain plants in general, especially wheat, have formed a close relationship to humans, gifting them with the ability to farm and with that came enormous amounts of power and social structures, an entirely new way to live. A friend of mine said that “wheat is the most successful plant at cultivating humans”.
And then time passes and there comes Hofmann, already at child with a curious consciousness and a few spontaneous mystical experiences, grows up to explore these realms with chemistry, and then by coincidence, when working with ergot in the lab, LSD called him, as he put it, and he was not looking for it. Now invite Jung who will tell Albert that what remains unconscious will seem like fate. It was already known before Albert's discovery that ergot induces hallucinations.
