Let me just say that I was the person that I use to be a big proponent of the idea ayahuasca use until I find my own ceremonies.

It could have been the shamans I was with (maybe one was a brujo as I received a weird kind of psychic attack vision of him) but I dont think that Ayahuasca is as benevolent as people make it seem.

My experience was very painful and to this day I believe I received a negative energetic implant during my trip. Not to mention I only purged twice which means that the spirit really stayed inside me. Perhaps I was a good host for it.

I no longer believe the spirit of ayahuasca to be as high vibrational as people make it seem. 

It almost seems like a vindictive women spirit. A bitter women. Very kali energy. But at the same time somewhat resentful.

I also believe it doesn't like to go outside its "tribe". It came to the shamans for a reason and probably likes to stay there for it's own reason and not spread to all these American tourists.

Psilocybin on the other hand I believe was meant to raise consciousness of humanity and is a million times more benevolent but I doubt ayahuasca to be an uprooter of eveverything great in my life and pretty much derailed it although in some ways i did get stronger due to my hypersensitivity. 

Lastly, it seems to attract a cult following which to me indicates its brainwashing/psychic kidnapping traits. Everyone I journeyed with was pretty off and the ones that I saw doing dietas for month/years seemed to be extremely troubled for the most part.

Proceed with great caution.
