This book expertly navigates through the iconography of mushroom symbolism throughout the ages. One clear message comes through: mushrooms have played a central role in the evolution of human consciousness, and indeed religion. Thought provoking and well-articulated, the authors present a solid case for their thesis. This is an important book to contemplate. If true, the very roots (mycelia!) of Christianity were inspired by the use of deeply guarded and secret sacraments: magic mushrooms.
