finally something I get to chime in, if only because of convenient location.
I live in Colombia, close to the Amazon, and in late years it has become relatively common in these areas for indigenous tribes to host Ayahuasca/yage (DMT in ingested form, with MAOI) even for occidental outsiders and I happened to try it.
Before Yage, I had a lot of concepts in my head of the interconnection of everything in the universe, of the eternity of my soul, of good as the only true motor of things, and of all depressions a delusion, all of these were vague concepts and ideals but what Yage did was shift my mind so that in those 8 hours it had effect on me it became a certain experience, as certain as the keyboard I type on right now. it was a huge huge help, it is hard to stay within that mindset but I regard it as a sort of north star, no matter how deluded or depressed I might get by what happens I know that what is real, is what I experienced then. All flaws of character all confusions are but a convoluted form of this pure energy that animates me, that I felt so purely then.
Therefore, I would not class it on the same level as LSD or Psilocybin, I have not tried LSD but I have heard it is much like Psilocybin and I just dont think it's on the same category.
Ash, I too used to see Alcohol intoxication as a potentially aiding chemical before Yage, but after trying it, it became clear that all it did was intoxicate and dumb down aspects of my psyche, and any aspects that stood out simply did so because they were still working normally. In contrast, Yage truly heightened the better aspects of my being to a more spiritual level.
I have tried marijuana before and after Yage, and I have to say Yage affects how marijuana is synthetyzed in me, it has become a little bit hallucinogenic after Yage and has a slightly more spiritual bend to it.
I cannot imagine the experience of smoked DMT, since it's supposed to do the same it did to me in 8 hours, condensed in 15 minutes, DMT allegedly is pretty much just the biggest mindfuck you can(not) imagine, while Yage is seen as a motherly and caregiving experience in comparison.
Crowley allegedly used cocaine and other chemicals in his rituals, did he not leave behind any instructions on how to take them? all I have heard of psychedelics in a ritualistic enviroment comes from indigenous perspectives (well, and Mckenna), so it interests me what Crowley came up with from his own alternate background.
