On September 19, 1966, Leary founded the League for Spiritual Discovery, a religion with L*D as its holy sacrament (by doing this, he hoped to legalize L*D based on a "freedom of religion" argument) Although The Brotherhood of Eternal Love would subsequently consider Leary their spiritual leader, The Brotherhood did not evolve out of the League for Spiritual Discovery. On October 6, 1966, L*D was
made a Schedule I controlled substance in the United States, which made it illegal to possess, manufacture, or use for any purpose. All scientific research programs using the drug were shut down. During late 1966 and early 1967, Leary toured college campuses to spread the psychedelic gospel by presenting a multi-media performance called "the Death of the Mind" which attempted to artistically replicate the L*D experience. Leary said the League for Spiritual Discovery was limited to 360 members and was already at its membership limit, but he encouraged others to form their own psychedelic religions. He published a pamphlet in 1967 called Start Your Own Religion to encourage people to do so. In February 1968, Leary was evicted from the Millbrook estate, and shortly thereafter moved to California. He was arrested again on December 26, 1968 in Texas for possession of ma*****na. In 1970, Leary received a ten-year sentence for the ma*****na arrest. During this time period, The League was closed down, and all centers abandoned.
