I could show or teach humanity any one thing it would be to dare to let the psychedelic experience into their life, at least once in a lifetime, for a few hours.

Agreed. Just reading @choogirl's series on aya and reminding myself of why the plant world is so incredible - some of the best psychonautic revelations (love that term, by the way) have been with plants and nature. Much better guides and teachers than men with agendas.
