So i keep hearing of people signing up for these very unique excursions deep into the Amazon in order to take part in one or more Ayahuasca ceremonies with a trained shaman, and others seeking the same kind of enlightenment. Eg: http://video.google.com/videoplay?d...1&ei=8LicSdXZBI3m-AHf8O3uDw&q=docid+ayahuasca what I'm wondering is where do you sign up for this stuff? The guy in the video describes having to write an essay to get approved and being subjected to 6 months of preparatory work before actually going. I like that because it gives it a certain legitimacy... i can imagine there are a lot of hoax or bad shops out there. Anyway please let me know if you have any information, this kind of experience would be a dream to me.
