"Encounters with apparently sentient beings are reported by half of all first time users of the naturally occurring psychedelic DMT, yet the question of DMT beings and plant sentience, interspecies communication, discarnate consciousness, and perhaps even dialoguing with the divine has never been systematically explored. In September 2015, ten of the world's leading luminaries noted for exploring the mysterious compound DMT (dimethyltryptamine) gathered with other researchers at Tyringham Hall in England to discuss the subject. Over three days, they pooled their expertise from a wide range of subjects--archaeology, anthropology, religious studies, psychology, neuroscience, chemistry, and psychopharmacology, to name a few--to explore the notion of "entheogenic plant sentience" and the role of DMT as a conduit between Spirit and Matter. Offering cutting-edge insights into this visionary domain, this book distills the potent exchange of ideas that occurred at Tyringham Hall, including presentations and discussions on DMT entities, the pineal gland, the possibility of DMT as a chemical messenger from an extraterrestrial civilization, the Amazonian shamanic perspective on Invisible Entities, morphic resonance, and the science behind hallucinations. Contributors to the talks and discussions include many leading thinkers in this field, including Rupert Sheldrake, Rick Strassman, Dennis McKenna, Graham Hancock, Jeremy Narby, Erik Davis, Ede Frecska, Luis Eduardo Luna, Bernard Carr, Robin Carhart-Harris, Graham St. John, David Luke, Andrew Gallimore, Peter Meyer, Jill Purce, William Rowlandson, Anton Bilton, Vimal Darpan, Santha Faiia, and Cosmo Feilding Mellen."
