I agree, one of the saddest mistakes in the past century is the plants' suppression in modern society.  I'd love to get involved in some kind of future research dealing with enthnobotany/pharmacology in the Amazon basin, particularly the ayahuasca.   I'm glad to see the building of larger retreat centers when foreigners can come to experience the aya, even though I'm sure it has it's cons also.  I want to come in contact with traditional shamans and take in all the information they have to give me, and also the experience.  If I can't explore the DMT realms with my career then hell or high water I'll take a plane down there anyway.  I've never taken traditional ayahuasca.  I've contemplated preparing a pharmahuasca brew with acacia and syrian rue, or acacia and caapi, but I want to feel fully confident in the preparation process before I do this.  On the other hand I'd prefer to witness the experience of being under the guidance of a trusted shaman. 

I have nothing against taking aya in your own home, alone or with others.  I think its successfully done every day with profound results, however I believe the shaman holds techniques to guide and work within the realms of consciousness, I don't have that power lol.  Sure it's likely (hate to jynx it), that I could do aya in my apartment and see and explore just fine, but the shaman can actually navigate me and show me things I would have been too ignorant or too flabbergasted to understand by myself.  The icaros and rattle rhythms and rituals, and also the power of mind that I will be connected with, all that I can't provide to myself. 

I like to think that something so powerful can only be suppressed for so long.  That it will one day spill out, even more than it has the past 100 years, into the human mind.
