Zig Zag Zen: Buddhism on Psychedelics by Allan Hunt Badiner
Zen and psychedelic exploration share a common concern: the liberation of the mind. Through numerous essays and interviews by such luminaries as Terrence McKenna, Charles Tart, Jack Kornfield, as well as visionary art by Odilon Redon, Mark Rothko, Alex Grey, and more, Zig Zag Zen is a provocative and thoughtful exploration of inner states and transformation.
