Huxley's exploration of consciousness expansion through drugs began in the 1930s. Moksha, a word from Sanskrit, means liberation. The speeches, essays, interviews, and letters gathered here focus on the realm of visionary experiences and the liberation of the mind. In May 1953, Aldous Huxley experimented with mescaline for the first time, and experiences with consciousness-expanding drugs would accompany him until his death. This exploration touches on areas of psychology, medicine, ecology, literature, and politics. Ultimately, what Huxley envisions is a technique that helps individuals beneficially apply their transcendental experiences in the sphere of 'the other world of this world.'.
