The Invisible Landscape: Mind, Hallucinogens, and the I Ching (Paperback)
A thoroughly revised edition of the much-sought-after early work by Terence and Dennis McKenna that looks at shamanism, altered states of consciousness, and the organic unity of the King Wen sequence of the I Ching.
Terrence McKenna has spent twenty-five years exploring "the ethnopharmacology of spiritual transformation" and is a specialist in the ethnomedicine of the Amazon basin. He is coauthor, with his brother Dennis, of The Invisible Landscape: Mind, Hallucinogens, and the I Ching, and the author of Food of the Gods.
