You are likely tiring of my mushroom references, but perhaps psilocybin grows in pig shit? Just a loss for any other explanation. Perhaps the pig was just a faithful companion, who knows, I've pondered, but pretty much come up empty so far. I'm not the person to know really, but psychedelics didn't always have the negative connotations they have today. I suspect that started in the Eurocentric world with the Spanish Inquisition.

You are right, there are other legal channels to "the other". Also right about Cayce - no drugs. I think he did a reading on himself and it was determined he developed his trance ability while lying and dying on a battlefield in his previous life. Apparently he lived for several days, dying on that field without relief and learned to escape his body prior to actual body death.
