The late great Terrence McKenna was raised in Colorado and grew into a well known ethnobotanist, mystic, 'psychonaut' (taker of heroic psychedelics doses), lecturer, author, and an advocate for the responsible use of naturally occurring psychedelic plants.
He spoke and wrote about a variety of subjects, including psychedelic drugs, plant-based entheogens, shamanism, metaphysics, alchemy, language, philosophy, culture, technology, environmentalism, and the theoretical origins of human consciousness.
He often spoke about an attractor at the end of time.. He left Earth in 2000, So young.. Just 53 years of age, McKenna should have had a whole other life with us, however the words he left us with are truly irreplaceable.
Psy have listened to every McKenna lecture - some twice. Enjoy
