Thoughts on “True Hallucinations” by Terence McKenna

This book has been on my shelf for a while. I picked it up years ago from a used bookstore called Reader’s Corner that was next door to where I worked at the time and is now closed (the sad fate of too many bookstores). I had heard of McKenna but had not read any of his work. Anyway, in my current quest to reduce the number of unread books straining my shelves, I decided to read this one.

Overall, I liked the book. It was certainly well written and the subject is fascinating for me. I am very interested in shamanism and consciousness, and McKenna explores these topics through the lens of psychotropic plants and mushrooms. My one criticism, though, is that he sometimes slips down the rabbit hole of truly bizarre ideas, but I suppose that is par for the course considering the subject matter. Anyway, for this post I will focus on the parts that I thought were interesting and gloss over the weirder stuff.

I have been fascinated by the metaphor of the jungle as a symbol for the subconscious and primordial mind. As McKenna recounts the arrival in the Amazon, he senses the jungle not just as a symbol of the subconscious, but as an actual manifestation of the deeper consciousness.

Everyone in our small expedition felt, I think, the sense of something opening around us, of the suspension of time, of turning and turning in a widening green world that was strangely and almost erotically alive, surrounding us for thousands of miles. The jungle as mind, the world hanging in space as mind—images of order and sentient organization came crowding in on all sides. How small we were, knowing little, yet fiercely proud of what we knew, and feeling ourselves somehow the representatives of humanity meeting something strange and Other, something at the edge of human experience since the very beginning.

Something that has always intrigued me is the ability of sound vibrations to alter consciousness, and hence alter reality. This is done through chants, incantations, and certain types of music (shamanic drumming, binaural beats, etc.). McKenna describes how they used sound vibrations to affect space and experience dimensional shifts.

Further experiments with the psycho-audible warp phenomenon yesterday raise some interesting new questions and enhance our ongoing understanding. I choose the term “audible warp” because my experience thus far, coupled with what I have been told, leads me to believe that this all has to do with vocally generating a specific kind of energy field which can rupture three dimensional space. I do not understand if the field is electromagnetic, but it seems to bend space in such a way as to turn it upon itself through a higher dimension.

I firmly believe that, as a species, we have barely scratched the surface of consciousness and its power to mold reality. I can’t help but wonder if ancient civilizations had a deeper understanding of the potential of human consciousness. McKenna certainly shares these thoughts.

Perhaps the shamanic traditions of this planet are the keepers of an understanding that uses the human body/brain/mind as its vehicle, leaving the present state of the art, which our own “scientific method” has achieved, a very poor second. This is really an old idea—the siren song of Pythagoras—that the mind is more powerful than any imaginable particle accelerator, more sensitive than any radio receiver or the largest optical telescope, more complete in the grasp of information than any computer: that the human body—its organs, its voice, its power of locomotion, and its imagination—are a more-than-sufficient means for the exploration of any place, time, or energy level in the universe.

The rest of the book goes quite deep into the exploration of consciousness through altered states. There is a lot packed in to the just over 200 pages, and if this is a topic that interests you, it’s worth reading. But be forewarned—there are some very strange ideas put forth here, but if you have the fortitude to sift through it, you will discover some interesting ideas regarding the mind and its hidden potential.
