Visionary: The Mysterious Origins of Human Consciousness

Graham Hancock (Author, Narrator), Brilliance Audio (Publisher)

I have been privileged to have had many wonderful teachers.
Not all of these teachers have been human.
Indeed, some of my most important lessons were given to me by Ayahuasca, the
“Vine of Souls” or the “Vine of the Dead,” a concoction of two rainforest plants.
Ayahuasca is a powerful psychedelic brew that has been used for thousands of
years by Amazonian shamans to make out-of-body journeys to what they believe
are the realms of spirits. Unexpectedly, some Western scientists who have drunk
Ayahuasca themselves (rather than simply read about it) are inclined to agree.
