League for Spiritual Discovery

[6][7] IFIF was subsequently disbanded and renamed the Castalia Foundation (after the intellectual colony in Herman Hesse's The Glass Bead Game), when Leary and Alpert set up a communal group in 1963 at the Hitchcock Estate in Millbrook, New York.

The Castalia Foundation hosted weekend retreats on the estate where people paid to undergo the psychedelic experience without drugs, through meditation, yoga, and group therapy sessions.

[11] During 1965 Castalia Foundation members collaborated with artists, including the media art collective USCO (The Company of US), to reproduce the LSD experience in improvised audio-visual psychedelic shows in Manhattan.

[8] Anyone at Millbrook could read publications such as Leary's Psychedelic Prayers (a book of poems inspired by the Tao Te Ching meant to be used as an aid to LSD trips), and underground newspapers to which the group subscribed.

Nicholas Sand, the clandestine chemist for the Brotherhood of Eternal Love, followed Leary to Millbrook and joined the League for Spiritual Discovery.

[21] Owsley Stanley encouraged Sand to shift his operations to California, and offered him the services of his lab partner, Tim Scully.

Later, on October 24, 1968, LSD was added to the list of Schedule 1 substances, which made it illegal to possess, manufacture, or use for any purpose in the United States.

[22][23] At the end of 1966, Nina Graboi, a friend and colleague of Leary's who had spent time with him at Millbrook, became the director of the Center for the League of Spiritual Discovery in Greenwich Village.

[19][29] Leary and Alpert gave free weekly talks at the center, and other guest speakers included Ralph Metzner and Allen Ginsberg.

[24][29] 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 LSD experience.

[4] In October 2006, the League for Spiritual Discovery was restarted, taking all of the original intents of the prior organization as a foundation, but updating the message and expanding the work.
