The Multidisciplinary Association for Psychedelic Studies (MAPS) are now offering Myron Stolaroff’s book The Secret Chief Revealed online in its entirety. The book tells the story of Leo Zeff, one of the pioneers of the underground psychedelic therapy movement, and features contributions from other luminaries such as Sasha Shulgin, Albert Hofmann and Stanislav Grof. Of course, most of us prefer to read on paper, so if the book interests you then stop by the MAPS bookstore and purchase the paperback – not only a worthy addition to your bookshelf, but you help support MAPS in the process.
