This book takes an in-depth look at the spiritual and psychotherapeutic potential of the amphetamine derivatives MDA and MMDA, harmaline (the active compound in ayahuasca), and ibogaine. To distinguish them from classical psychedelics such as LSD and psilocybin, Naranjo coins the terms “emotion-enhancers” and “fantasy-enhancers” for these substances.
[Grof’s work] is the most important contribution to personality theory in several decades.
—Abraham Maslow, founder of Humanistic Psychology
If I am the father of LSD, Stan Grof is the godfather. Nobody has contributed as much as Stan for the de-velopment of my problem child.
— Dr. Albert Hofmann, research chemist ad author of LSD: My Problem Child
I know of no work that so well incorporates the findings of Freud, Jung and Rank, adding fresh insights, which the methods of those psycho-therapists could never have achieved. I do not doubt that many others working in this field would find Dr. Grof’s discoveries a basis for a whole new strategy of research.
—Jean Houston, Ph.D., The Foundation for Mind Research
