Accounts of the test subjects' experiences are the best part of this book. Listening to this book has made become much more curious about psychedelic experiences.

Great book full of details, and informative facts. the author, just like in any good research project, included all the details. it's up to you, the reader, what to do with it

Definitely is a technical research study. The first half of the book was a bit dry, but still seemed necessary to appreciate the efforts in setting up the research. I found the second half more interesting as it went into the encounters of the participants along with post observations, from both author and subjects.

this book is a unique account of the scientific study the inner journey with psychedelics. Top recommendation!!

Very comprehensive inside story of the most intriguing subject. Fresh and enlighting perspective inspiring constructive criticism and provoking different approach to much controversial subject.

Very interesting study. Wish there would if been more about each subject however. I feel like the author definitely held back (somewhat understandably) but I feel like a lot of truth has been purposely edited out. Still, since there likely won't be another study like this anytime soon, it was awesome to delve at least waist high into to the subject.

Why, why is it that all enlightened men must struggle to lift the masses, and that the truth must be sought in the darkness. This book is one of the brighter lights leading humanity out of the oppression of darkness and into the light.
Thank You for your light Doctor.

Dove down the rabbit hole and could relate many of my own experiences with the stories inside.

it was a great book. a little slow, but the information in it is so captivating.
i listened to it straight through.

The story of one of the most amazing research projects ever done!! A must for alternative theorists
