Several friends have done the Ayuhuasca ceremonies and they all basically fall in line with what's already been said. There doesn't seem to be any inconsistency or exception to the experience that I've encountered personally or that has been logged by others on the internet. It's a very very powerful experience not to be taken lightly.

This is really what has surprised me the most. The uniformity of experience is striking. It seems to center around an internal mind battle between evil-good; with good eventually prevailing. The most plausible explanation to me (of course, I haven't tried it and so who cares what I think) is that this is a representation of the natural internal dynamics of the human mind represented in a post-language framework. It makes sense to me that the human mind battles with its own existence and self-worth but then eventually comes to a realization that infinite creativity/good is, in the end, attainable. I think Terrance McKenna said the essence of what you find is "love" or "the ultimate aesthetic/beauty". In the Benny Shannon book he claims it is eternal creativity. Similar things... both "art-related".

"wherever the fuck it is that you go."

Well said...

when you're in that space it appears that science misunderstands what's happening completely.

I think the key from the experiences I've read is that you are in post-matter, information-based reality. Or in the words of Ab-Soul in the song "Pineal Gland" (a song about DMT): "I'm in a place where matter don't matter, just spirit molecules and geometric patterns."
